By the way, if you access this switch from front passenger side tire, it is much more easier than accessing from the top (hood side). You don't even have to take off the tire or anything else, it's right there.
Thank you for your time and effort in making this video. A no no-sense comprehensive guide to trouble shoot the GM ac on these suv’s. With your video as a guide, I could trouble shoot and FIX my ac on my GMC Yukon Denali in less than an hour. Thank you very much. 👍👍👍
If your freon gas is full (check with guage) then it might be your pressure switch. But i am warning you and everyone here...these kind of switches are non-refundable. So please do your homework before installing the switch.
I had the same problem on my 2010 acadia...replaced compressor and pressure switch...worked for a week and not working now. Any ideas would be appreciated..thx.
So I have the AC blowing but as I turn it up to blow harder it will blow less and I will leave it in that position as I drive it will blow harder by its self. Also the temp changes.. is this connected to my issue?? Did this happen to you as well
Well, I hope it's the switch that went bad on my truck. Sure hope there isn't a leak, that would seriously suck. At least I'm in MN so I don't *need* it, but would be nice to have it. It's January. And it's 10 degrees outside. No clue why I am watching videos about this lol. I don't need it for at least another few months lol
Haha, right. Just to let you know that when I changed the switch, I didn't loose gas, it might leak only for a second when you are pulling out or putting back in. Otherwise it should be okay.
I am not sure but I think you should call Autozone or Advance auto with your year and model, they should be able to tell you.. these kind of switches or electrical parts are non returnable able once you open them. Good luck.
@@thatswhatshesaid6326did anyone ever figure it out I have a 2012 Chevy traverse and I’ve had everything replaced front and rear ac line air compressor twice fuses checked and it’s still blinking and not working
If you have symptoms like I had it in my suburban then most probably it's switch. But keep in mind these kind of parts are non-returnable, so you better do your homework before you open the package.
That's a good question and i really don't remember it. I think compressor doesn't kick-in unless it detects freon...sorry can't recall that how was it acting up? If you find out please update here for other people. Thanks
No i did not lose any freon, when I took off switch, It has a pin, it did make a sound of gas coming out only at the last thread of switch, once you take out the switch completely, it stops. Just like when you push the Tire air pressure pin in and air comes out, when you let it go, it stops. Make sure you check your new switch if it comes with O-ring, it it doesn't then you don't want to damage the old O-ring. Also check my PINNED (updated) comments l. 1st comment, it's much easier to access switch from front passenger tire. Read it, you'll understand.
Mine has same issue super cold for 2 min then the a.c clutch diss activates then 3-5 min hot air activated again at random already changed that sensor but no luck. I’ve replaced a.c compressor and accumulator as well.
Ok So I have Denali 2007 GMC and I’m not sure if it’s the same problem it blows air and I put Freon and I was cold Like for 1 hr after that got back to hot 🥵 do you think it could be same problem??
our 2010 Tahoe had rear AC and the metal lines wore a hole in them under the back passenger door. Seems to be a common problem with that set up. Dealer wanted $1200 to replace, evacuate air, and recharge system or $600 to cap, evacuate air, and recharge system so it had only front AC. There's a store out of Niles, MI that sells rubber HVAC lines to replace the metal rear line for $3-400 or cap kits for $75.
Depending on your metal/aluminium diameter 1/2" or 3/8" Look at this on eBay www.ebay.com/itm/Dorman-800-642-1-2-Aluminum-Line-Splice-Repair-Kit-/283513379053?_trksid=p2349624.m46890.l49286
There's also a repair kit for rubber AC lines and lots of videos on the UA-cam, to be very honest i have replaced one of the AC line and refilled with freon without vacuuming the ac system and it's been 2 years so far AC is working great. Just follow the safety guidelines and you can do it on your own .

Sorry, I am not sure, but this is Santech part # MT1247. Read my first PINNED comment, it tells the exact location of this pressure sensor, see if it helps.

Thanks for this extra tip! I have 2014 and it is hard to get to from the top.
Thank you so much!

You're welcome, these are really encouraging comments.
UA-cam has given me so much and I am trying to do the same for others.
Thank you sir! This was an easy fix. Took me longer to look for the tool and get the right part.But everything worked out in the end.
@@bumpcity9794 you're welcome
Fantastic video. Informative- straight forward. Clear. Thank you.
Thanks for the supportive comments
Thaaaank u been 2 mechanics 3x 2 complete systems 8 months time and this sensor was all I needed..

Man you have saved me a lot of money & trouble thanks alot
I am glad it's helping people
My 2006 has both. One on the accumulator and one on the line where you show in the video next to the compressor.

Awesome !!!!
Shukar hai kisi kay tu kaam aa rahi hai video. Please subscribe kar daina mera channel.
I couldn’t locate the high pressure switch, thanks for showing me the location
Do you know the location of the low pressure sensor?
How do I fix but the lights only mine won’t show me the temperature high or low anything but my ac works good
Thanks for posting this.. i was wondering where that switch was as its not located on that easy to get accumulator...
Glad I could help
Hands down. Great video
Really appreciate it!!!
Is this the low or high pressure sensor?
Hello. Did you habe pressure in the system before u chance the part?
Yes, pressure stays full, it won't leak any freon gas
So wish I would’ve watched this before letting a coworker, who “knew” what he was talking about, pressure up my Enclaves UPPER AC line w/Freon
I have a 2007 gmc acadia and mine is just blinking could u tell me what I would need

@@juanl.carrizales5313 seems like a leak somewhere, also if you replace the compressor then you need to add oil in compressor.
@@juanl.carrizales5313 did u get it fixed? So many people are having this problem on GMC acadia's but I haven't found a solution yet
Thanks my friend that was a big help
You're welcome.
I've learned so much from UA-cam community and I am trying to add my share in it.
Thanks for you video I fix my ac problem
Welcome 👍
Thanks! Big help!
Thanks
So I have the AC blowing but as I turn it up to blow harder it will blow less and I will leave it in that position as I drive it will blow harder by its self. Also the temp changes.. is this connected to my issue?? Did this happen to you as well
No it did not happen to me. It seems like your blower is going bad.
Did you figure out what it is? Mines starting to that
Well, I hope it's the switch that went bad on my truck. Sure hope there isn't a leak, that would seriously suck. At least I'm in MN so I don't *need* it, but would be nice to have it.
It's January. And it's 10 degrees outside. No clue why I am watching videos about this lol. I don't need it for at least another few months lol

Meth is a helluva drug
This issue is going in with my 2012 chevy traverse could it be this same part?
I am not sure but I think you should call Autozone or Advance auto with your year and model, they should be able to tell you.. these kind of switches or electrical parts are non returnable able once you open them. Good luck.
Hey, I've got a 2012 traverse with this issue also!
I have a 2012 with this problem as well. Did either of you replace the part?
@@thatswhatshesaid6326did anyone ever figure it out I have a 2012 Chevy traverse and I’ve had everything replaced front and rear ac line air compressor twice fuses checked and it’s still blinking and not working
Thanks for your time and video it’s very helpful and a good tip on how easy it is to get to it
Thanks for the encouraging comments.
U are welcome and it’s very true
Al cambiar esa válvula escapa el gas refrigerante?
No, it does not
At least, not in my case, it did not leak any freon
How do i know if mine is bad ? Just change it and see ?
If you have symptoms like I had it in my suburban then most probably it's switch. But keep in mind these kind of parts are non-returnable, so you better do your homework before you open the package.
What is the bad part? I don’t see where you note that
Jason, "Pressure switch" is the bad part. This is what the video is about.
Part # Santech. MT1247 , if you pause the video at 0:58 it got all the information.
Did your coolant fans come on when that switch was bad
That's a good question and i really don't remember it. I think compressor doesn't kick-in unless it detects freon...sorry can't recall that how was it acting up?
If you find out please update here for other people.
Thanks
I have a problem to my fans won't come on and plus I have a burning smell coming out
Did you lose any Freon or is this just an instrument connection? Surely not if electrical connections on both sides?
No i did not lose any freon, when I took off switch, It has a pin, it did make a sound of gas coming out only at the last thread of switch, once you take out the switch completely, it stops. Just like when you push the Tire air pressure pin in and air comes out, when you let it go, it stops.

Try checking your radiator fan? If your car is Running over 45-50+ mph and AC is running fine then it Means your fan is not running
Ok So I have Denali 2007 GMC and I’m not sure if it’s the same problem it blows air and I put Freon and I was cold Like for 1 hr after that got back to hot 🥵 do you think it could be same problem??
If you have to keep filling up freon, this means you got a leak.

Was that the low or high side pressure sensor?
