Heated seats

[geo3xk]

Ive been troubleshooting my heated seats for a few days and i finaly got it working. I checked the wires under the cover and they are ok, switch worked and all fuses were good. But still no heat. so i wrestled the relay out from under the seat and was testing it with my led test light. probed one wire and heard it click and turned on. So i searched for some wiring diagrams and finally found one and i think what was happening is the temperature sensor under the seat no longer limits the flow through it. It is supposed to in some way with a resistor or what not limit the flow of electricity depending on the heat produced. So what i did was hook up a led with resistor on it to ground on one side and the other side went to the signal wire on the relay, and viola heat! I think I am going to run the led into the side of the switch for the heated seat so i also will see when its on. Just something I thought I'd like to share with you guys I've seen a few people with problem like this and figured it might help someone out. I was also thinking about posting some pics of it when im done.

Is it me or did you just bypass the thermo controller?

You're correct. I tested the crap out of that line im just not sure what on it. It has continuity and resistance just not enough resistance to turn the signal on. I figure my ass will let me know when its too hot and then i can turn it down or off. If anyone has any idea what the temperature switch in the seat looks like or even how it works id love to see it. I tried everything i could think of and this so far is the only solution i found seeing as i'm Not cutting my seat to peices and I'm not an electrical engineer, lol.
