I have a 2003 GMC Yukon (hope that is OK) and the heated seats on both sides are not working. On the driver seat, there is no power -, ie: seats won't move at all. Passenger side seat has no heat but power. I can't seem to find the fuse or whatever the problem seems tto be. Any help is much appreciated!!!

PS---Everything was working fine until a few days ago!

Yeah--I checked in the maual and didn't see it labeled anywhere. Also checked in the side (interior) fuse box--manual seems to have dozens of fuses--but not the one I need.

A bit more specific information would help!

do the heated seat buttons light up and instantly shut off... or nothing at all?

I don't mean to hi-jack this thread, but I thought if any resolution is brought to this it would be nice to have them all in one thread. I have the opposite problem with the seat heaters in my 03 Suburban, the lights come on for about one second and then shut off automatically, both driver and passenger side.

The lights for my heated seats come on for a few seconds and then shuts off. What is the problem and how do I fix it?

Any one have an idea? The wiring under seat looks OK but the lights on the switch still just come on and then shut off.

From what I've seen is that if the lights come on then shut right off you've got a short in the wiring. If nothing happens like in the first post it should be a fuse issue.

srt4,
Thanks for the reply. The lights do come on and then shut off right away. I assume a short. Could this just be a short in the heating element and that needs replaced or in the wiring?

This has recently happened to me. I have a 2004 Thaoe. I read in the manual last night that there is a button you can press to turn the heated seats on and they will stay on only until the seat reaches a certain temperature. I wonder if this sensor is out of camber and needs to be reset? I read on another forum that in 2005 GM issued a patch or OBD2 scan to fix this. I guess you could call it an electronic update for your truck. Has anyone else heard of this? I wonder if this magical scan could fix all our problems...

As a part of troubleshooting can someone pull the fuse that would control the seats and when the correct fuse is pulled the seats/heated light will quit working. Then you can report to us what the correct fuse is called. I know sometimes the naming convention they use does not clearly ID what it is actually for. This would be a good step 1. I would be suprised if the seat control and seat heater would be on the same fuse though.

I just checked my manual (for my 99 NBS) and in the fuse block mounted in the drivers side edge on the dash it shows fuse 13 is for a few things including the power lumber seats and device A (I am unsure if this is a larger fuse or a relay) is for a few things including the 6-way power seats. In the fuse block under the hood there is a large fuse labled heated seats but in the manual it says "not used". I am looking at my manual electronically and my truck is not with me so I am unable to look at it.

Ok I have a question then, I have an 02 Yukon Denali and both of the front seat heaters don't work....But the switch turns on when I hit it and will stay lit till I turn the car off. The fuses are all good, so would it be the relays that are bad or the elements? Any ideas thanks

I have to resurect this one from the dead. Has anyone been able to diagnose the problem here? I'm on the verge of purchasing new heated seat switches and giving that a try -

My 99 Tahoe manual says the seats won't heat up unless the seatbelt is buckled. So, there must be a switch in the latch assembly. Possible that it has poopoo the bed.

Wanna trade seats? I couldn't get mine to STOP working. The @#$ things had a mine of their own and could come on and cycle thru the settings randomly. I could turn them off and in a few seconds they would be back on. The problem was that it was only like 60 degrees out and I didn't want or need the heated seats.

That would keep the srs systems lamp / warning on also.

The body controller has the ability to self diagnose the heated seat system. 03 Yukon for sure...

The switch has a TSB indicating improper switch replacement due to user error - not sure what that means except your not holding your finger correctly...

I would pull bcm codes and see if it holds the answer. Otherwise pinpoint testing, broken wires in door jambs, under the seat, power to the switch, etc.

To those that have the heated seat switch lights come on then shut off after a minute or so... had the same problemin my 2003... the D/S element was shorted. You could see it was burnt. At night with the seat cover off, you could see it sparking if you moved it a little. Easy fix -not uncommon. D/S normally wears faster than P/S. The two are wired together so when one shorts, they both trip the breaker.

I currently have this problem, can you elaborate about the heat element, it's location and removal? A pic might even be nice..

Well guys,

This past week i bought a replacement door switch for my drivers heated seat. I pulled the door pannel off and replaced the old switch with the new one last weekend. I pressed the button and it lit up, but with the same result; it kicked right back off within a few seconds.

This is a picture of the switch i replaced:


When my switch light turns off, I always hear a clicking sound beneath my drivers seat. It leads me to believe (along with what i learned this last weekend) that the problem is with the heating element, below the seat. From what i understand, to access the element you have to pull back the seat covering. Is that correct? Could anyone elaborate?

The heating element is like a piece of fabric that sits under the leather. Its held in place front and back by what amounts to tape to the foam. The new one comes with it - peel and stick like a band-aid.

To change, you unscrew the seat control switches and plastic panel on the side of the seat. The switches or connectors unscrew from the inside of the panel also IIRC. With the switches out of the way, the leather is pulled off the seat cushion. Its held on by way of plastic channels that are part of the cover that sit over the edge of the metal frame. Pull the channel off the metal and up it comes to reveal the heating element. I didn't completely remove the cushion leather from the seat and left it attached in the back. I pulled the element up (ripping an insignificant amount of foam with it due to adhesive). The element wires snake through the back of the seat and simply plug into the truck harness. If you are looking underneath the seat, the connector is bright green. I used a long pick to pull the wires to where I could reach them with my hand. The key is to lay the new element as flat as possible when sticking the adhesive to the foam. The "right way" is probably to take the seat apart or at least to fully remove the leather from the cushion in order to get it perfectly flat in the back where the seat cushion and seat back come together but I was able to get it pretty flat just pushing it back with my fingertips then peeling the adhesive strip. Installation of the leather and switches is reverse of removal.

Its really a piece of cake job. Budget 30 minutes. The old one should look burnt up in spots which will confirm that its the issue. Element was like $90 through a friend in the industry.

Same problem, but I think mine is the door switch. What was the part number and where did you get it from? Quick search of Ebay and amazon are pulling up empty.

I have a problem with my 2003 Tahoe (mileage: 89,000 miles) seat heater on the driver's side. It seems to have a mind of it's own.

The seat heater comes on by itself and cycles through all three settings; 3-lights, 2-lights, 1-light, all off and then repeats over and over; 1, 2, 3, all off.

This happens both while in motion and while stationary.

I removed and disabled the seat heater controls in the driver's side door panels. No joy and it keeps my bottom side HOT all the time.

The passenger's side seat operates perfectly normally.

In desperation, I removed the 25-amp CB to disable both the front (L and R) seat heaters and motors, but that also disables the seat adjust motors.

Does anyone know of why the left seat heater is going nutz?

Any inexpensive fixes?

Thanks!

Al, I have the exact same problem with my driver side heated
seat, as you describe it, with my 2003 tahoe. Did you get
any clues as to what is causing this to happen? Thanks.
