Thread: Adding a heated seat

This weekend I decided to see if a heated seat would work in my car. The junkyard had a nice seat they said I could have for $25 I was eager to give this a try since i couldn't find a thread on here about it and i had no clue if it would work. My car is a 97, donor car is a 99. I'm not sure which years this will work on. Sorry no pics

Things needed:
Heated seat obviously (This one had power lumbar also)
The switch and little cover plate
Console harness out of the car with the heated seat
A rather large torx bit (T50) and a 3/8 ratchet.

First thing to do is pop up the center console. The shifter will need to be in N or D. Take it completely off so you have more room. Make sure your parking brake is engaged so your car doesn't start rolling.

Pop off the connector on the left side of the conosle and then disconnect all the other connections. They include the 12v adapter, shifter light and a few others. Don't break the connector because you need them!

Next is to slide the seat far enough forward to get to the bolts that hold the seat in. There is one on each side of the track. Then disconnect the harness under the seat and rock it forward to get the "hooks" out of the floorpan and take the seat out making sure not to scratch up your center console or anything else.

After you've got everything of your donor car...or if you bought everything seperate do the same procedure to the car the seat is going into.

After your seat and console harness is out put the new one in and do everything in reverse order.

Finally enjoy your warm butt!!

I would assume this would work with the passenger side seat if you can manage to find a passenger heated seat. You would need the harness out of that car also since the console harnesses are only wired for the options you have. EX if you don't have heated seats like me there won't be any wiring for them at all in the conosle..same applies for passenger heated seat..if the car didn't come with it then it wont have a connector in the console for it...but it more than likely is in the main harness like mine was.

Yes, I did this with my GP. It was very easy.

Yes, your right the heated seat does have its own fuse...it should be labeled "HSEAT/LUM" meaning heated seat/lumbar. If you have this fuse in your fuse block your car should have the wiring for your heated seat.

Look under your seat on the connector. There should be 2 orange, 2 black, a pink and a blue wire on the car harness...not the seat harness...theres a freakin ton of wires on the seat harness...at least on mine there is. Anyway if you have those wires i listed on the car harness you should be good to go.
Honestly I think every car is setup with the wiring in there because it's part of the main harness...the harness with the switch in it is a pigtail that comes off of the main harness.

Just check it out on your car, theres no way for me to know if its on your car lol.

Ive read about this quite abit accually. there was also a case were they used a driver side in a pass side since there is no heated pass seat. hard part is moving the controls over to the other side and that didnt seam hard

i did this in my OLD GTP, and before i sold it i kept my GTX interior and put it in my new GTP for a year now i have had no heat because its not working, i know in fact the seat works, and the switch, but when i put it in my new GTP and inserted the fuse i can select high or low but theres no heat in the seat, and leather is by far VERY cold in the winter.

LOL thats why my GTP gets stored in the winter and my Blazer has cloth

Damn.. Take that lol, I would think there is some sort of resistor that might of gone bad or a relay.

What do you need to know.

Our heated seats are controlled via the switch. In the switch is two resistors one for high and one for low.

In the seat bottom is a thermister than tells the relay when to turn on and off. (I'd say this is your issue, maybe a wire came unhooked in the heater, like the typical issue where they don't work.)

The most common failure in our seats is the connection point where the wires going into the seat bottom connect to the heating element wire. The heating element wire is very thin and can be hurt easily. Reconnecting the wire is typically the free fix to having a heated seat again.

Brought over a write up I've had on other forums etc.

If you guys would like a true how to add heated seats, I've got that as well.

Added them to my 97 Bonneville and 00 Regal, as well as a few other cars etc.

i would like to see the true how to add heated seats. my car came with no heated seats and cold leather + my butt = me unhappy right now.

Yes and no.. I detailed how to make the harness...lol

how did you get the texture to be right in the plastic after you sanded it?

SEM makes the paints that match all car maker interiors so that you can repaint if needed etc. They also make a texture. A few test tries and you learn how close and how much to apply.

Add in adhesion promoter and you'll have great success


Texture


Somewhere i have a pic of these two plus the correct paint for a few different things. The paint though is graphite.

Now to go a bit off topic. Which do you want, homelink, fog light switch in duplicate or the original?


Anyone recognize the fog light button? Once I put homelink where it originally was, I needed a different button.


ABS defeat, EWP off switch, IC pump switch and PAC LED hole

Which part?
Homelink
Retaining steering wheel control
Drag bags in the rear springs to keep traction
Onboard air pump (factory) to pump up tires when leaving the track
Window regulators that don't break
AL7 seats (18 way) with heat added (never had it factory)
Oil pressure gauge (factory)
Boost gauge (needle, not a bar)

Might have been because the motor had
S1X
1.8 Rockers
Stage 3 heads
Gen V
WBS stage 3 IC
Meziere EWP and 20gpm pump for IC
Flow detect kit
SLP's

Funny part is the fat car got 2.5" piping from the factory. With rear drum brakes ...ack.

FWIW, here's how I did a Regal.
