heated seat not working....

[linetrash]

on the driver's side of 07' Yukon. The back works fine, but the ass doesn't work at all. The passenger side works perfect. Is the element bad? Thanks in advance for replies.

 

[sievz7]

wanted to give this a bump since I am having the exact same issue.

All lights on the switches light up, the backrest heat works, passenger/rear captains heat works, just not the ass on the driver's side....

anyone know where to start???

 

[Mr. B]

Sorry guys, that must really suck. BTW, mine are working perfectly!

 

[sievz7]

That's alright Mr. B....while it is cold as "F" down here in Southern IL, I'm sure you are really enjoying your weather up in the wind city today....lol....

I can live without my ass warmer down here....

 

[07ChevyHoe]

I was going to post the same thing but mines the exact opposite! The ass works great but the back does not heat up!! Pass side works fine. I hope someone can shed some light on this...

If I press the button which is the seat/back position only the ass warmer works. If I press just the back heat button it lights up, no heat, then turns itself off after about 30 sec!

The bottom in mine is not working but back is and I have replacd seat element and switch in door now and still nothing the light for bottom does not light up in door either any body have an idea?

Taking mine in for this tomorrow morning, as well as checking for a driveline leak.

When the weather was still mild in the fall it was alright not having a heated seat. But lately it's been in the negatives to single digits when I drive to work and I can't stand sitting on a block of ice any longer. If I find out the warranty won't cover it, I'll pay to have it fixed but won't be a happy camper.

Hoping my GM Major Guard extended warranty covers both issues.

May be a dumb ?...but have you check the fuses and wiring to the seat?

Update as of now: Found leaks in the lines from transmission to cooler and to reservoir so all lines replaced on warranty.

Heated seat: New module ordered and took a weekend to deliver from Michigan and get installed yesterday which DID NOT FIX MY PROBLEM, according to my service manager.

So they are back to square one, trying to figure out what is wrong with it. I have a tiny chevy malibu loaner from the dealer, 6 inches of snow on the way tonight and a 1700 pound piece of oak that needs to be trailered that I can't without my truck.

I'm a pretty patient person and I know the dealership is working on it, my service manager even called me personally on his day off yesterday to give me an update, but it's just getting aggravating that they don't have a fix for this on their books.

Sounds like the problem is the heating elements. They are both separate parts. You should be able to remove them yourself and order some from rock auto or somewhere to replace.

 

[AJ847]

Service manager told me that the heating elements are different/ don't burn out in LTZ's with heated & cooled seats, its supposedly a different system than just heated seats. Problem is that the dealer already has my truck in their hands, so i can't just demand it back in pieces. Essentially I feel like I'm up a creek without a paddle... or 4x4.

 

[AJ847]

So the final resolution on the drivers heated seat is in... after a whole week they had to wait for 2 different parts to be shipped in at 2 different times (very frustrating). The best I can say about this whole ordeal is that it only cost me $50 under my extended warranty to fix, but the $750 I am expected to shell out to repair the loaner I damaged will haunt me.

Anyway, the heated seat module under the seat had to be replaced, that was the initial fix my service manager had told me. Once that did not work, they had to order the heated seat back piece as well, because they work in tandem and I guess if the seat back burns out the entire system takes a crap.

I have the paperwork from the dealer with part numbers, too lazy to get it from the truck in my driveway but if anyone wants I can always put them up here.

Now I get to deal with my rear wiper that broke off because the metal ring holding it to the motor RUSTED AND BROKE OFF. F'Ing GM.

Same situation on my 07 XLT. I've read a bunch of threads, and this is the most info I've found that matches my issue.

Bottom heats, back doesn't. Has anyone been able to troubleshoot the system? Wiring diagrams?

I'd love the same.

Currently my buttons light up when I turn mine on, but neither the back or ass get warm. I'd like to know where I can check what.

Anyone with ideas?

were you able to find a fix for this problem ? I have the same issue as yours. both front heated seats doesn't get warm, although the switches lights up and stay up.

 

[Truestyle Scott]

i posted a fix for the escalade seats. topic is down a little ways. i dont know if the yukon or tahoe system is the same though.

I had a problem in my 2011 a couple of years ago and the dealership replaced the elements in the passenger seat as well as the switch in the door. It worked for a day and went out again. Back to the dealer where they had the truck for over a month diagnosing wiring and computers. These trucks use complicated circuitry to activate the heated seats, not just a simple wire from the switch to the seat. My recommendation would be to let the dealer diagnose it even if it costs more. You'll drive yourself crazy trying to find the issue, I know I did. The seat has worked great ever since. BTW, they covered it under warranty.

My 2010 Tahoe Heated seats stopped working and none of the elements on either seat works. The lights on the control buttons illuminate but the elements do not function. This is very frustrating because I've had it to the shop twice and they can't find the problem. Anyone who has a solution or similar problem I would love to hear from them. I did check the pins on the connector under the passenger seat on the Motorola control module and the pins are not burned or damaged in any way.
