- Here we go again...more modern FANCY cars with BROKEN "features".
This 2012 Buick Enclave can't open it's power liftgate...at all! Just latched shut.
Owner tried "checking fuses", but lost one in the process and gave up.
Let's see what the problem is with this Buick, and if we can at least get the trunk open and make it operational again. Will any expensive parts be required?

Ivan not only saved a Buick and his neighbor’s job, but countless relationships teetering on the brink of disaster who got the flowers they needed to continue their commitment. Ivan is now transcendent in his skills. 😂😂😂😂.
I helped deliver flowers in the XL-7 too...the manual swing tailgate and big trunk is simply perfect for the job :)

17 subie Forester touring hatch woes. Worse when it rains in this seaside town. No way to open. Have fiddle with all the buttons on the fob dash manual door locks in that they don't auto lock there is a door armrest lock button. System has not totally failed but there is no manual way to open the hatch that came with the model.
I expected no less from you Ivan. You do a great job narrating what you’re doing. Your neighbor is fortunate to have you there.
I amazes me how newer vehicles don't have an easy access emergency tailgate/boot relaese .Some upmarket models in all brands go for 'upsell' gimmicks that inverably fail over time & they have been doing it for decades & what really annoys me is elderly people get sucked into buying top of the line models thinking that paying more money gets them better vehicles when in truth it is the opposite.(my daily rant over).Cheers Ivan.
It's hard to imagine a more complicated system for the tailgate. Initially, I thought it was the power motor that failed, but it was just stuck in some crazy position. Simple repair, made hard due to need to disassemble part of the tailgate. I still prefer mechanical latches 🙂
Automatic convertible tops still take top honors in the Rube Goldberg category. Even as early as the 1960's, the engineers must have been smoking whatever was in vogue while sketching out the convertible top mechanisms 😆.
@@hightttech LOL, very true 🙂
@@hightttech Yes, but they then also added in lots of hydraulic cylinders, so there needed to be a battery operated pump, and a nice complex mechanical clockwork timer system, with dozens of contacts on a complex cable assembly, to operate it as well. 2 gallons of hydraulic fluid, a 30A power draw for the pump, so they decided to add to the load automatic windows and automatic closing and opening doors as well.
You're the guy that explains the movie before it starts.
Those power goodies are always nice to have-until they break! Power tailgates, soft-close and self-closing doors, memory seats, you name it-customers want them but rarely think about the hassles of fixing them when something goes wrong! Also, I have a soldering pencil much like yours, it runs on 12 volts or AC, and I really like it too. It didn't come with a battery but I can take it anywhere and use it with a little battery pack I made for it.
Moisture on copper equals corrosion. Very good diagnostic and repair Ivan!
Key in lock to unlock, pull on handle, opens every time with or without corrosion. I like my manual latch.
Spray the tailgate weatherstripping with silicone spray before you give it back to the guy.
Yep good idea.. clean it off with rubbing alcohol and finish with some dry lube..
Silicon spray also helps release doors if used before ice freezes them shut.
Works great in the window tracks of sluggish power windows also.
Daughter has the identical car. Thanks to previous video I was able to fix it. It had water in the inside fuse box and it would run with the key removed and would not turn off. Installed Tupperware lid above fuse box covered with an absorbent pad for any moisture. These Buicks are not for the average owner. There is always a gadget broken one day and it will work the next day. This is the best channel for car repairs. No one else will try to troubleshoot with diagrams. It has trained me to use my meter and check current and grounds. I would love to come for a day and watch and learn.
Kansas City Auto Electric here, another good one Ivan. Great Job! I had one of those the other day with a 2007 GMC Denali. Ours was the cheap rubber switch. I checked for continuity and there was none while working the button.
Did the other switch work or the fob? Or was it completely disabled like this one?
@@PineHollowAutoDiagnostics Completly disabled. I have to assume that the switch was stuck closed. The fob did not come with the vehicle so I could not test that. Fortunately, I figured it out early so I did not need extensive testing.
Travesty not to have a key lock cylinder in any doors anymore.
By design so the dealership can rip people off.
Can't even get a truck without a stupid button to open the tailgate now.
Designed so there’s less points for a thief to use to get into
Amen... It's time for the lock picking lawyer to chime in... 🤣
Back in a more rational era, we were trained to
'key off" when things got out of control. How do you "key off" when there's no key...?
They are going down the path of Apple, by removing hardware ( mechanical components such as earphone ports) in order to save money, as Cars have already had electric release motors for the trunk/ tailgate, so why not just completely eliminate the mechanical lock?
Nice video and diagnosis. It’s amazing how complicated a single latch handle could turn into in the name of progress. 😂
On our older GMs, I've found that the wire bundle in the liftgate / tail door become brittle from repeated flexing when opening / closing. The stranded copper wire becomes brittle and breaks inside the insulation. It's only apparent when you tug on the wire.
Ivan, you are a master at this stuff! Trouble is most vehicles now have all those gadgets! Even so called "base" have bells and whistles! LOL. Thanks for the great trouble-shooting on that tailgate!
Next vehicle I buy, I need to make a checklist of systems that MUST have a manual override. No override, no purchase. This stuff is just getting downright dumb and ridiculous. Thanks Ivan.
All of em are required to have a manual release if its an enclosed trunk but sometimes they still hide the damn thing. But usually a yellow pull somewhere inside. If it werent for all the creepy piece of shit rapists and kidnappers we wouldnt even have those..,
@@Z-Ack Was kind of just thinking a physical key turn/pop. I guess that's prehistoric thinking now.
the mentality that created the yugo if you are old enough to remember. and it wasn't a bad idea
@@richardcranium5839 Good idea, terrible car? I do remember the Yugos. They'd have sold far better if they'd arrived in the 1950's/60's like the VW Beetle.
The scary thing is how hidden they can be, especially in cars with pushbutton door releases.
I've seen videos of people locked in cars after a crash because the car self disables itself and they don't know where the manual release is since it's not in an obvious spot. Like I believe Tesla has it pretty hidden on some models, and the poor person is panicking while someone is struggling to smash the window and help... Talk about a nightmare.
Superb job Ivan, there’s one thing while they keep making complicated cars you will never be out of work , I think your videos are just about the best ones out here on this sort of work at the moment you explain everything so great that even an old guy like me could understand carry on with the great work👍❤️
Hi Ivan, another interesting video.
I would be replacing that "wire" completely with some decent wire.
The only reason it is small gauge is because of the small current involved, that doesn't mean the insulation should be so feeble.
The fact that the cable clip had worn through the insulation goes to prove it is inadequate.
The reason the operation suddenly came good could be because one of those switches intermittently failed and gave an out of sequence signal.
When you got into the back of the door and manually tripped, it probably got everything back in sync.
I think you will find that hole and the lever you active is made to be done with the finger, not everybody has a probe as such to push it.
The errors you originally had tended to suggest one or more switches did not respond as expected when it was closed.
Remains to be seen if it happens again.
another genius diagnostic and fix. Well done.
Nice fix Ivan. Wouldn’t it be nice if they used a thicker gauge of wire in these cars? At least they have an access plug to get the tailgate open.
Great NPR repair. I wish cars were simpler like your neighbor (my age). I've started to mess with cars again but just the basics. My electronics started when vacuum tubes were just being replaced with transistors.
Sweet. I got in right after vacuum tubes. Boards were huge, stacked high and cost a kings ransom, so we fixed everything. The disposable electronics of today makes for less fun on the bench.
I still have my tube tester.
@@robertsmith2956 If you're interested in vacuum tubes watch Mr. Carlson's Lab
It scares me to think how many everyday mechanics would've just replaced modules and still not fixed anything. You're a special kind @pinehollowautodiagnostics and your fine work leaves us floundering who are stuck in the midst of part swappers.
A fine video again Ivan. If that Buick has the 3.6 engine, you would do your neighbour a favor by telling him to sell it before it chucks the timing chain.
Stay gold.
I tell him 5k synthetic oil religiously. So far so good!
Unfortunately GM decided to use these LLT engines an these Lambda platform crossovers longer than in any other application - through 2017!! Many GM vehicles ditched the LLT as soon as 2012. Not these though. Aside from using synthetic, use a GF-6A and latest Dexos (gen 3) for best timing chain protection. Most modern 5W-30 synthetics seem to adhere to these specs anyway.
Good Job Ivan, You always seem to track down the real issues!! Well Done.
The strange behavior for the tail gate can also be caused by the vehicle sitting for long time which causes the battery voltage to drop. This gadgets do not like low voltage at all.
I have a 14 Enclave so I am saving this video. Thanks
After watching this entire video, I still don’t know if the lost fuse was ever found! I feel the same way now as I did after reading “Catcher in the Rye”.
Ya I said I reinstalled it!
@@PineHollowAutoDiagnostics well I missed that part. . . Lol
The education this lad is giving for free is amazing! Not sure how I'd keep up with today's "Advances" without guys like Ivan!
Interesting one, "old" car problems are always more fun. I had a "similar" problem with a 2011 VW touran (European) , but it was down to plastic components breaking in the latch system (good idea for something you use often, i don't think)....Keep up the good work Ivan.
Your trouble shooting "Sherlock Holmes" skill in searching for answers to situations like these NEVER fails to educate me. Great work...
One of my customers has a super rusty 02 Tahoe that he primarily uses for taking garbage to the dump so when his lift gate switch failed, verified it was the switch then installed a push button next to the handle so he could still open it one handed and know i can spot it a mile away with that black button on his tailgate.
That's just crazy - good troubleshooting! The system was apparently locked up via logic, otherwise one would have expected the dash and keyfob commands to continue to function. Maybe they designed it to use logic to make it work in an illogical fashion! My car (an HHR) appears to use the same little rubber switch pad thingy to open the rear hatch. Although mine does not have a motorized lift gate, it still uses the switch and a motor to operate the latch. I always thought that was strange - why not have a mechanical latch release acting on the latch directly? The answer , I think, is that reliability isn't a consideration and they focused on elimination of the latch linkage and a "real" release handle. And my car doesn't even have a latch release for the hatch on the dash or on the key fob!
Volunteering to deliver flowers on Valentine's Day? That is a new one on me. He must be truly bored
I volunteer too! It's actually pretty fun :)
I think the door hadn't been open in a long time and the weather seals were stuck and that's why non of the other buttons worked. When you broke the weather seal free everything worked except the rear door switch.
Awesome job
Hi, great video as always. Scanner Danners lighter trick for stripping thin wires is awesome!! 😊
I have the same exact issue on my '11 enclave but haven't bothered tearing into it. Thanks for the video.
Awesome. That would have an entire new tailgate at the dealer ;)
Ivan, You're a good neighbor. Great information
You never cease to amaze me Ivan. Even after all these years, I still love to watch you work. Thanks!
Thank you so much for the support and comments John, means a lot to me! 🙂
I love you videos and your troubleshooting methods. You helped me troubleshoot a bad ignition switch in a 05 Dodge Caravan by watching your test light videos. Thanks to you, I bought a "Black Friday" Think Tool Pro that I love. I'm practicing with it every chance I get. I also agree with your "Why new cars suck" rant. I tried to help a neighbor with his BMW that had one of those stupid joystick shifters. They put the cupholders right next to that stupid thing and a drink got spilled in it. Great design guys! I have to work on crap Chinese TVs every day and it's the same type thing. These things are designed to fail, so they can sell you new TVs every 2 years. Keep up the good work. PS: We've got some killer MTB trails down here in GA!
I had a 2015 Honda CRV, 1 year old at the time…had this exact problem, but it wasn’t so extreme. Stopped working when it was cold outside.
Took it to dealer for warrantee, guess what they said…works fine for us, have a nice day.
They of coarse checked it during the day when it was 90 degrees outside.
An EEVblog talk with Jack Ganssle, an embed electronics guru, Jack mention that survey's showed that people rated these features as 60-70% of the value of the car. They expected them to drive but would pay for the bells and whistles. Mfrs will continue to put these in as long as people will pay more for them.
I'm part of that 60-70%. Now I need to find mechanics as smart as Ivan.
Hi Ivan, years ago I would put silicone sealant on the newly soldered connection then slide the shrink wrap over it and shrink like normal.
Rich
Can you imagine if it had one of those footswing sensors and what that would add to the complexity of the system? 😮
Even if you had not figured out that bad wire, getting it unstuck from the inside allowed the keyfob and console switch to work.
That's a nice looking vehicle. I like the interior.
Great you can be so much help to your neighbors. 👍👍
Those TS100 irons are awesome tools. Good job, yet again, Ivan. 👍
You proved again some shouldn't be getting obsolete from cars like a simple old fashion key hole on trunk and doors while having all this fancy unreliable automation.great job and nice fix ivan.cheers
I bought a 2022 Buick envision essence last week. Super amazing. I hope mine lasts as long as this one cause man, it has a ton of fancy stuff. (mid trim)
You make it seem so simple my friend.
I remember that was a common thing on them buicks gmc chevy. i would replace the whole piece instead of repairing and of course shop would charge for the whole piece. them latches also would go nutty too
Not surprised to see green corrosion back there. There is quite a bit of road spray that gathers on the back of vehicles, or we could just call it salt spray🤣. That is kind of weird how aside from the corroded wire issue, the other problem seemed to fix itself, strange. Don't you miss the days Ivan of just having a key cylinder in the trunk and a key in your hand was all you needed to open it? Talk about overengineered systems on vehicles. I guess with the cylinder the only thing to worry about was the cylinder seizing up.
I remember the old Caddies with the power latch. People would forget it was soft close and slam the trunk breaking the latch mechanism. I guess I'm showing my age😂. Nice repair npr.
wow thats a weird failure mode...one broken wire system is bricked no DTCs.... I admire your patience this vid would NOT be PG if i were on cam diag hahaha
You are great man, fantastic, there is nothing you cannot fix keep it up, and thank you for sharing
I wish I had a good neighbor like Ivan.
Peace.
Thanks, now I can get my ex-mother-in-law out of the trunk, she's been in there for over a year ! 😋
xD
hahahahahahahahahahahaha Great one
Lol sorry I would have had a tough time with this...but I know how to measure for a short, you have the test leads very cool.
Hes lucky to have you as a neighbor . And to not get a ticket for driving with those expired tags for nearly 6 years..😆
Those are vintage PA plate stickers that they phased out lol
Tailgate probably was manually closed with a flat battery, so it was unable to detect state, so locked out. Button broken meant no way to do the test at tailgate, so it stayed in that intermediate state till opened, and motor controller saw a valid open and close position, then it would respond to inputs again. Safety feature so a remote operation (fob or front) would not result in a door related injury, it was waiting for the door to be manually opened to generate a valid intermediate moving then open or closed state. Till them will not move.
Yes those buttons do fail with time, had the same, and did not want to buy the expensive genuine part, or wait for the aftermarket one, so put an alternative waterproof one in there instead.
Like my uncle says all the power stuff is all krap just krap. Over time 😂
For those unaware, the 'adhesive' heat shrink tubing is basically just heat shrink with a coating of hot melt glue on the inside. I use it on flash drives, so that I can write on the heat shrink. Writing on the flash drives rubs off quickly.
Correct, but the hot melt is not all the same, I have some for automotive and some for underground. The underground seems rubbery compared with the auto.
@@CrimeVid I don't have experience with anything but the standard stuff; I was just letting people know not to panic if they ran across 'goo'. Underground is probably less alcohol soluble.
@@tbelding Plenty of different hot melt glues around, 3M makes over 500 different types, all in the same exact rod format, all for different industrial uses, and then also supplies them in larger bar format for use with their range of pneumatic dispensers as well, along with literally thousands of preformed shapes as well.
Interesting symptoms, nice diag and fix :) My parents had a 2014 VW Golf Mk7 which started acting up, randomly the tailgate didn't open from the VW badge and sometimes hill assist didn't release automatically as it should. They indeed just replaced the car before more troubles appeared :D
Thanks for the video Ivan great job. There isn't that many New cars out there unless you want junk 😜☺️👍❤️ it. Take care of yourself and family and be Blessed ❤️❤️.
Well done Ivan, the owner will be as happy as a dog with three trees lol.
I'm sure that a bit of grinding to give the cable more space and a glob of hot glue would fix it for millions of years :-D
I helped a friend with a car a few years ago, the rear hatch would not open, i found that the module wasn't sending the power to open it.
For an emergency bodge (woman wanting to shop Now now !!) i connected an old joystick with a red button to the open wire and 12 volts feed through a 3 amp fuse.
I disconnected the module wire so i didn't feed power to the module.
She took the car to a repair shop a week later and replaced the duff module, i bet they laughed at the joystick lol.
Enjoying the video, where will it lead, it's an adventure 😁!!
We replace those exterior release switches all the time. They get water inside them and short out.
I have a 2009 BMW X5 where all buttons to open the lift gate work, but button on the lift gate that should close doesn't. Funny thing is I can remove/install lift gate fuse and the close button works once, but no more until I remove/install the fuse the next time.
I wish I was your neighbor, Ivan! 🤣🤣🤣Thanks for the video... I have 2008 Saturn Outlook (basically the same vehicle) and I could completely see this happening to me... Green crusties for the win and electronic tailgates for the loss! 😁
nice trouble shoot and repair on the Enclave.
This is why I'm clinging on to my 04 Tahoe. Sure it's a gas burner, but I can fix anything with a hammer and pliers. 🙏
That is weird fix!! But i prefer traditional lock!! Can't believe green pus can knock it out!! But great fix on those wires! Awesome job!!
well done Ivan, you are a genius
Very nice Korean Buick your working on. Never thought I'd see the day when Buick wasn't made in the USA.
Vin 5 = made in USA :)
@@PineHollowAutoDiagnostics my bad, I was thinking of the encore, but still I would have never thought a Buick would be built anywhere but USA.
Ivan, you fixed the Buick better than new. That repair will most likely outlive the car! 😉
Ivan love the work nice job i hope that stays fixed
Put a dose of silicone spray on a rag and wipe down the rubber door seal. If the door is stuck, the safety sensor just shuts down the action of the door. Just like hitting the creeper on the way up.
Just had a similar problem on a 2018 Enclave Avenir but this was severe cold (-32C) induced and the whole system lost its mind. I wasn’t aware there was in internal access to open the rear door but once I pressed the release button (it’s now different than what’s in the this video) all the activation buttons came back to life. It’s just too bad that kind of thing isn’t in the Owner’s manual, which is in the Buick App. How much trouble could it be GM, for you to provide that information given it’s digital. Thanks for this Ivan!
Your still diagnosing but you did say you could open manually.. I might try to open manually then see if it will rest and start working.
The accelerated process of corrosion in the presence of a current source with easy access to a return path (grounded sheet metal in this case) in the presence of an electrolyte (salt water) is called Stray Current Corrosion. It can be very aggressive, much more so than Galvanic corrosion (common green crusties). However, the real issue with the overall design is not the small gauge wire (should be a minimum of 18 AWG) with a miniscule wire jacket thickness (although this is bad from a vibration and chaffing standpoint), but the horrible diagnostic circuit design for the tailgate switch to ground. Although, the design does use a dedicated ground wire for the switch input, which is good.
The switch should have an internal set resistance directly across the contacts, so when the switch circuit is intact it forms a known voltage divider with the module pullup resistor. This way the module knows if the switch wiring is intact. As an added feature, if the module had a divider internal as well as a resistor across the switch, you could diagnose that the wiring is good and the switch itself is bad (high resistance) which in my mind would be full diagnostic coverage. So, the problem is the module diagnostics don't provide complete circuit and switch integrity coverage. This technique of a combination of resistances providing different relative divider voltages (usually ratio-metric) for diagnostic purposes is very common in automotive electrical design. It is surprising it wasn't used in this module.
Great engineering comment 🙂
Remember when you used to be able to just pull a mechanical handle, and the door just opened? What was ever wrong with that design?
good thing the customer didn't take this to the dealership/local mechanic. i reckon even if they had pinpointed the corroded wire, they could have easily replaced buttons, modules and motors, just to make it worth it to them.
That was an awesome video my 11 Honda Odyssey is doing the same with the doors and the trunk doesn't work
I know someone who has a Benz with a similar fancy automatic trunk. One day it decided it was going to remain closed y'know, for security or something, and the dealer got him for a nice $2,500 to get it going again because it barfed up one of like four motors that powers it. Ouch!
I recently quit my flower delivery Job........ For years I hated valentine's day 🥴😓. It's actually valentine week in the industry, the day of and day after.... You get very familiar with gas stations you have never been too. I'm so so so glad I'm don't deliver anymore.
But you know your automobile smelled super good!
I have an Uplander with Power Sliding Door problems... it will close but then you hear grinding noises for a few seconds and then it reopens. I purchased a A30M xtool, but it can't do live data to the PSDM... no trouble codes! I read it maybe a detent switch in door that detects latch... might just have to open the door and do some direct measurements to figure it out... fun, but not fun!
Hmmm. Maybe wipe the door seal down once or twice a year with silicone spray so it doesn't stick together. Maybe.
KRYTOX
Maybe apply some conditioner, silicone or dressing of some kind to the gate seal. It did seem to sound a little stuck.
I'm Dan, Martha's my wife. Good job, Ivan.
Great Job!
Thank You Ivan as always your the greatest at diagnostics. 😁
The left side assist piston is actually a motor that lifts and lowers.
Just had to replace both on my wife’s Explorer.
It has a separate rod
Those actuator controlled handles always fail at some point, failing that the microswitch.
Next thing to go will be the rear wiper motor. Water gets in and they develop a mind of their own.
Its an overly complicated mechanism but you can't blame the fanciness for the failure. A lack of maintenance and use caused the problem. On top of the wire the entire mechanism needs to be properly lubes; hinges, latch, and maybe the motor. Gunk just built up to the point where the tailgate got stuck. I'm sure read it as an obstruction which prevented it from running until the tailgate was freed up. It would help if GM added an obstruction PID but its a mechanical fault. The mechanical tailgate on my truck wasn't working for the same reason when I bought it. Previous owner never used it. I've seen the same thing on other trucks. A liberal dose of WD40 gets it moving and then you clean it up from there.
Good work Ivan.
Nice to know that our modern vehicles are just one corroded wire, or one rat-chew, away from full disablement. I wonder how many miles of wire there is in your typical vehicle these days?
Ivan you like the modern technology on your computerized soldering iron but not so much on computerized vehicles. I agree that this adds another world of complexity and hence points of failures to the system but that goes with any progressed technology like e. g. power steering. You would miss that from a modern car, wouldn’t you? It has also more complexity and potential to fail than a 1960s car with manual steering. So as we learned to like power steering we also learned how to fix it. So I think that’s just how it goes. We need to adapt to the progress and need to learn how to fix it. So that’s how you make your living and pretty cool and interesting videos for us 😊
Power steering and my electric soldering iron are much more useful and reliable features than a power tailgate 😉
I have twice similar exactly problem with Opel Astra. My friend also once and he was problem to how open manually the trunk for repairing because he s car was at just that very time loade full of heavy material and no way to go near that open hook
another issue i seen a few times is objects stuck in the latch like clothing - socks - carpeting etc...but thats an easy fix
One is always going to pay for convenience. People want to be lazy and have the machines do all the work for them. This car has 3 ways for the machine to let the owner to be lazy.
And none of them work! xD
I haven't watched the whole thing (I'm @11:00) but I will bet the wiring harness from the body to the liftgate.... Or water intrusion cooked the module if it's in the rear fender well. Edit - well I was pretty close, wiring harness, but not at the joint...
Ivan, you need a bigger garage. And a camera (edit,etc) person, so you can start focusing on the diagnostics only. I would be more than happy to pay a monthly subscription for your videos.
Bro, some of us are on welfare though.

Nice job Ivan!
