I was just reading through a TSB regarding heated seats and their repair procedure and I grew rather upset.

They list three different directions for different year spans. It seems that with each newer model, they make the heating pads smaller and smaller. Moving from damn near the entire seat being heated, to just the very seat bottom, and lower back area.

Why in Gods name would they do this?

p-ricks.

Not sure why they would do that... But have you ever found yourself on a very cold day with the seat heater on... Everythings just great. But maybe you take a turn sharp and slide/lean to the side a bit and you can feel that cold leather... It's be nice to get my heater going before winter hits over here. Not sure if I should purchase the elements or not.

If My heated seats ever start to fail, I am going to look into fitting them like the "old style". So everything is heated, so as to avoid what you just mentioned.

Anyone got a wiring diagram for the heated seats for a 92 STS?

Here you go. Sorry they are in two files instead of one. That is the way I had it, but the file size was above the forums restriction

I don't have any experience with the older models, but my '01 DTS has an element in the center and two in the front of the cushion for your thighs. The sides aren't heated and you can definitely feel it when you shift in the seat. The seat back is one element comprised of 3 sections which cover the entire 'insert' part of the seat. My Toyota pretty much heats up the same areas, but the Caddy gets hotter.

Before buying elements, use the FSM method for testing them (you check the resistance). I just replaced mine and found that neither element will work if only one has failed. That is, for example, if the seat cushion fails the module will send little or no voltage to the seat back even though the element is okay.

Here is a link to my replacement procedure. It's not pretty but it was DEFINITELY worth it. I did both front seats. I might do the back seat later on as budget permits:

:eek::shocked2: THE HORROR!!!! I wouldn't be able to take my baby apart like that, it would hurt too much and I would be paranoid as hell that I would do domething wrong. It looks like a Frankenstien seat now, lol. I think that the elements in my 99 SLS driver seat have stopped working. The odd thing is that any car that I've ever been in that's had heated seats, I really never felt it all that much so I don't know if I would ever have it done, I don't think that it would make that much of a difference to for me. I wonder how much it would be to have a dealership do it or if I did do it myself, how long and how much parts would be.

I fixed it according to the TSB. The dealer would fix it the same way. They probably wouldn't use bright red duct tape, but that's all I had laying around (the TSB calls for cloth duct tape). It took a couple of hours per seat to remove it from the car, pull the covers/cushions off, separate the cushion from the cover, replace the elements and put it all back together.

The parts were $100 per seat (front seats) with shipping from GM Parts Direct. I'm not sure what type of seats the Sevilles have, but if they're like the Devilles they could be slightly less $$ for the parts as there are 2 fewer elements.
