Good Stuff!!!
My 2012 driver side rear door same problem.
Thx Dude
I'm so happy it helped! 🙌🏻 Rock on
The best videos in general i've ever seen on how to fix a latch issue on an F150!
Thank you for watching ☺️ I'm so glad it could help you!
Awesome! This fixed my super annoying driver side back door that wouldn’t lock. Now my kids don’t set off the alarm every time they try to open the door before I unlock the rest of the car haha. My truck is a 2014 XLT super crew. Luckily, I was able to make the repair without taking to door panel off. Hopefully it holds or I will be back to this video for the door panel removal if it fails. Thank you again for saving me a ton of cash on this repair.
Absolutely!! That's great to hear. This video and many more will always be here on my channel to help! 😁
Thank you for watching!
Great content. The double music will make your left eye twitch but still worth the watch. Thanks
The early days of filming 😆 I do apologize. I've learned a lot. Thank you for watching!
great video. my 2014 version of your truck has the same problem but opposite door. I'm sick of the door lock working intermittently and my passengers complaining so thanks to your cool video I'm going to finally get it fixed! You're awesome!!!!
I'm so glad it could help you!!
I was thrilled to save the $100 and to have the door function again. Thank you for watching! 👊
Thank you so much. I managed to push wire loom back without taking off the door and crimped the wires back together. It was only broken for 2 days but I keep all my tools in my truck and needed the lock/unlock to work. Really appreciate the video. Only took 15-20 min to fix
I'm so glad it could help you out!
Definitely subscribe because there's more videos coming soon!
I now appreciate the patience to fix such a problem. I an experiencing this problem with back and front doors. Got to find someone to do my repairs.
Thank you for watching! I'm glad it could help!
Thanks man, I have the exact same truck and I’ve just been reaching back and opening it from the inside for years now
I'm so glad it could help you! I honestly changed mine out with a new actuator thinking that was the problem till I discovered it didn't fix anything. It makes me happy to know it's helping people save money and time 👍
Thanks again for watching!
@@SmashingPunkFan I put off buying an actuator for years because I was too cheap to buy one. I watched your video and checked my harness and sure enough the little purple wire was split in half. Now I know what I need to do and you definitely saved me the hassle of swapping out the actuator for no reason.
Thank you!! My truck just started doing the same thing and I had no idea until watching your video, now it's fixed!!! I only had the purple with white stipe wire broke which I soldered and one other one was showing wire but not broke so I just put some solder on the exposed section and taped it up, all good now, thank you very much!!
Hey there Steve.
I am so happy to hear that you got it fixed!! You're very welcome. I will be posting new content for the F-150 platform whenever I encounter issues I fix on mine. Definitely hit subscribe so you don't miss out! 🤠 And thank you for watching
Thanks..
Thank you so much! I had 3 broken wires, 2 with cracked insulation.
I'm so glad this could help you!
Thank you for watching 😊
Thanks a lot!!! Best video that goes into detail exactly what to do.
No problem! I'm so glad it could help you out! 😁 Thank you for watching
Thank you so much, I have this problem with my rear door on my 2011 ford f150, I just saw the video and took panel off and found the purple wire broken like you described on the video, I was ready to go the dealer to buy the lock assembly but you saved my life thanks again..
I'm so glad it could help you!! Thank you for watching
Excellent video.
Thank you! 🤠
You the man. I just put a new door lock actuator in and was like ya kidding me. Seen this video qnd mine was just like yours. Thanks for the video
I'm so glad it could help you out. Definitely hit sub so you don't miss out, I'm always uploading new finds on the F-150! Thank you for watching 👍
Thank you this is what I was searching for.
I'm so happy it could help you ☺️
Thank you for watching! ❤️
Thanks for the video, I had changed the actuator and still not working. Saw your video and found the gray wire was completely cut. 👍
I'm so happy I could help 🙌🏻 Such a relief when it's not the actuator.
Thank you for watching!
Great, thanks. It's fixed after two years of rolling the window down to unlock it. Much appreciated
I felt your pain in that comment lol. Glad you enjoyed it! Please hit that subscribe button. I got more coming on the F150
@@SmashingPunkFan my 2012 f150 fx4 has 192k miles on it..keep em coming brother...it's falling apart. Anything on the backup camera screen going blue? Lol
@@FDDLERSGREEN I am actually about to make a video on that. Unfortunately the blue oval will break when you go to remove it, Ford later revised it with a new part number. It'll be in the video description when I upload it.
But, the connector gets dirt and road grime in it... If you could remove the oval without breaking it and clean. That might work. Helped with mine.
I'll definitely upload one on it soon
@@SmashingPunkFan I cleaned the corrosion off I found on my positive terminal and camera is back to working normally
@@FDDLERSGREEN That's awesome! I will check my positive cable post. Anything electrical from Ford seems to get quirky after so many miles.
I appreciate the feedback! 👍
Thanks for this Walk thru. I will be attempting this, this week. I just got a replacement door catch/actuator from a local Pick and Pull Junk yard, they charged me $25. While the junk yard did NOT have any 2012 F150's... it did have a 2014 Ford Explorer. Both vehicles use the same door latch/actuator! This morning I just tested my original catch with the use of an external power supply. It worked! So now I know I have a broken wire somewhere! Hopefully this is where its at!
I'm so happy it helped! Definitely check the door jamb. That's good news on your actuator, now you have a backup 😄
I couldn't help myself, so while at work I went out and looked, and sure enough, my purple wire with a gray strip was broken at the door. I added a piece if wire temporarily. Friday, I will be rebuilding the wiring harness.
Thank you. i have the same issue with my 2016.
I'm glad it helped you out ☺️
Thanks for this walk through! I had a lock that was intermittent and a speaker that was starting to go on and off. Found 2 completely broken wires and and 4 that were bare. Must be a real weak, bending spot.
I'm glad you enjoyed it! Seems like there could be an improvement from Ford on the design, but the truck does have over 407K miles now. That's saying something about their design and quality I suppose lol
Please hit that subscribe button. I got more content on the way very soon
@@SmashingPunkFan Great video, thank you for taking the time to make and share. This video was very helpful. I’ve also noticed intermittent electrical ghost that effect seat, window, speaker power mentioned above.
In addition to checking for broken wires in the door grommet, do any of you by chance know the ground locations I can check and clean? I know of the obvious chassis straps however are there any within the cab?
Thanks again for any feedback…other electrical issues Ive had in the past were with driver side tail lights. The wires/pigtail within the rear bumper connecting to the backup camera. Evap leak p0442/the fuel pump fuse relocation…aside from that and occasional known water leak issues my 09 king ranch. Thank God for UA-cam and folks such as yourself for sharing repairs.
@@Sheeeeeeeeeeeeiiitt you're welcome! I'm so happy it could be helpful to you! I would think the wiring harness under the dash might have a ground or two. But I honestly am unsure. If I spot one I will definitely post it here 👍
@@SmashingPunkFan Thanks the quick response. And again great channel and content….it’s clear you are passionate and take pride in what you do.
Great video.
Thanks for sharing.
I need to check my doors now.

Thank you so much for watching and subscribing!
I'm glad it's helping you. Definitely a common problem area for the F-150.
My speaker just went out and decided to replace them with Kicker 6x8. Well after install, speaker still doesn't work and now the door lock doesn't work. Pretty sure this is my problem. Probably look at buying a whole new wiring harness for the door. Thanks for the video.
Thank you for watching! I'm so glad it could help you out!
Nice video! You are very patient! I was swearing at that little cable connector just watching! It was a little annoying having the background music and also whatever music your mic picked up, that's what got me irritated and caused the swearing.
I appreciate it! It's the worst when I'm sweating during the summer 🤣
I didn't realize how loud my music was during filming. I definitely turn it down when I'm on camera now.
I appreciate you watching! Definitely subscribe so you don't miss out on the next video!
7:47 😅😅zzz
Have the exact truck in black, same issue with no locking, and Interior lights flicker on and off when i open and wiggle that door.. Assumed was the actuator. But definitely going to check this first. Great video.
I hope it is this for your truck too. Wiring issues are common on high mileage ford's, just glad some are easy to access like this bundle lol. Glad it could help you out! 👍
@@SmashingPunkFan you can pick up the lock/latch actuator off Amazon $38-$59 dollars albeit several different asian manufacturers but at least a couple sellers are stateside with >90% satisfaction rate. My 2014 lost both rear locks within 60 days of each other now my front pass door is a maylock 120 days ago now both outer door handles on pass side quit opening then just this morning making left out gas station the right rear door just flew open and wouldn't reengage the latch without a temper tantrum, some colorful language and several love taps around the latch did it finally decide to catch
@@codyyates3424 the price we pay to save a buck 😂 sorry to hear of your struggle. Seems like the truck is trying to keep you out lol have you checked any of the wiring? Or was it all actuators?
Thank you!! That’s the exact problem I had. Also, that round rod taped in there has really sharp edges. You could see it cut straight through 3 of my wires. If the edges were chamfered, I don’t think this would have happened.
No problem! I'm glad it helped you 😊
I've got the exact issue. Poor design. Thank you for the video. I almost went and bought a new lock motor.
I'm glad it could help you! Thank you for watching. I have several more videos on the F-150/common issues on my channel 👍
Thank youuuuuuuuuuuu
You're welcome 😁 I'm so happy I could help
My rear door open light is on all the time. I took it to my local ford dealer. They said it was the sensor in the door lock. $300 in diagnostic and parts later and it's still not working. I'm guessing this is my problem as well. Thanks for the walk through on how to get to it.
Hey Jeremy,
I hope this is definitely your problem. Alot cheaper and easier to fix at home than waiting at a Ford dealership. Thank you for watching! Please give it a thumbs up 👍
Good video but I can't open it hence the problem...to even get to any of that
You should be able to pull up on the door lock up top. If it's giving you resistance, the actuator itself is getting faulty and dirty inside. Had mine do the same, I ended up replacing the whole actuator a year or so later after this wiring harness repair.
Let me know if you have more questions 🤠
@@SmashingPunkFan already tried that the actuator is working fine but whether the lock is down or up it will not open
@Angela-ql9rz it soundsike your handle has come loose. Will it open from the inside? If not, you may have to get a tool to reach the lever and open it manually from the window opening
Thanks for the video! I have this same truck, same left rear door won’t lock or unlock automatically. Have you had issues with the security alarm going off frequently? Seems like this could be the problem
Hey, thanks for watching!
Yes, I have had an issue with it a few times. Once, the door was saying ajar going down the road. It wasn't. And, also locking the truck and setting the alarm to on, yet the back doors didn't lock. So, opening them did trigger the alarm.
All in these wires. They're a poor design, but easily fixable.
Again, thank you for watching! 😊👍
Curious, why do you need to remove door panel?
Can't you just repair within the door jam🤔
Hey there,
You could repair with the door panel in place. I removed the door panel to gain a little more room with my hands, and to pull the wiring harness backwards and out of the speaker slot to extend the length I was working on. But, I suppose you could do either way.
Thank you for watching 👍
Had a similar issue with the same harness giving me a "left door ajar" message. Broken wire as well. Now I'm having the door lock issue, so I'm sure its probably the harness again. I actually ordered a new harness from Ford. With that pinch point being what it is, I don't want too many splices in it. Any idea on how difficult it would be to change the whole harness out?
Hey, thanks for watching 👍
I'm not really sure how difficult it would be. There would only be a few more connections inside the door frame like on the lock actuator itself. Those were kinda difficult to remove. I'm sure it couldn't be much harder than at this point in the video. How much did it cost you just out of curiosity?
Have the same problem but my doors have the kids lock can’t open it from the inside
Made a video just for you. Have you tried your Child Locks with the key? Or do you think it's your wires?

So my 2013 has the same problem and the sad thing is I've been a collision tech for 32 years and still haven't fixed it yet 🤣🤣...but now I've got a new problem...my truck will just unlock all the doors just sitting there with no key in it...I started noticing when I would go out to get in it to leave that the doors were unlocked and I definitely locked my doors and you can use the key fob to lock them back and they will just unlock again....think it's time for a new truck.
That's a true bummer lol I know the key in with engine running won't allow you to lock the doors. It will automatically unlock them. I wonder if your truck believes the key is still in the ignition... 🤔 But then again, a new truck always sounds great!
Thank you so much for watching! Hopefully it'll give you a starting area if you do decide to tackle at home
Why don't you turn off that nasty music so someone can hear you
I apologize... Trying to make it entertaining in the dull parts. What part couldn't you hear? I'll gladly walk you through it ☺️

I have this EXACT same issue on my 2011 FX4 (only 37k miles). But, for some unknown reason, when this issue occurred, I also sporadically lost my factory backup camera. I can't imagine how a rear driver-side door harness could affect the backup camera simultaneously. I'm wondering whether the harnesses located under our driver seat might have similar issues... Anyone have thoughts or advice on this issue? That is, if there is no way that rear door broken wiring could impact the backup camera connection, then I would bet anything that my particular issue is a couple feet upstream beneath the driver's seat, where tons of other connections come together. Thank you to anyone who might respond!
I honestly am not sure if they're connected. The camera going out is very common unfortunately. Mine lasted till about 375k miles, then started giving me reverse image or not at all. Hopefully someone else does have some input 🤠
@@SmashingPunkFan Thanks!
I can't open my door to even do this
I had a similar situation after this repair. The dust built up so badly inside the actuator, even by hand was almost impossible to unlock by grabbing the lock post and pulling up. Once I got it open by forcing it open by pulling up the lock post (top of the door) I used WD40 and lubricated the actuator. It helped immensely.
Thanks so much. Next time don’t put 2 music theme, I want to hear your voice not your music.
I'm so glad it could help you!
Yes, I agree on the music. This was early on in my UA-cam videos. I'm still learning 😁
Thank you for watching!
Turn off the damned music!
I agree 😆 this was early on. I've learned to pay better attention when filming.
