fjorlandi Posted August 27, 2015 Report Share Posted August 27, 2015 This seems like an odd problem. My driver side heated seat in my 04 SS was coming on all by itself. Didn't do any trouble shooting, just replaced the door switch with a new one. Didn't help. Still have the exact problem. It doesn't happen all the time, and sometimes doesn't happen for weeks, then it starts happening again. It will shut off if I push the button to shut it off, but it might still come back on right away. Electrical problems baffle me. Tired of dropping a boat load of money at the dealership. I would really appreciate any ideas. Thanks. Quote Link to comment Share on other sites More sharing options...
chevybowtie72 Posted August 27, 2015 Report Share Posted August 27, 2015 U sure your not hitting it somehow. I tend to do this every so often. Also happens when a " new passenger" rides in mine. So how they hit it on and dont realize until there butt gets warm and i get that same question. "Why is my a** warm?" Quote Link to comment Share on other sites More sharing options...
90zxdriver Posted August 27, 2015 Report Share Posted August 27, 2015 Mine does this and has done this sine I got the truck. It only does it when it's wet out and the truck has been left outside. I figure it's something to do with the humidity. Don't know of any solutions. Just a quirk of the truck. Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted August 27, 2015 Report Share Posted August 27, 2015 Mine has done this from time to time ever since I've owned it. Never noticed a pattern to it and it doesn't happen often enough for me to worry too much about it. I just mash the off button and keep on truckin.

EXGM Posted August 27, 2015 Report Share Posted August 27, 2015 My guess is you all have a short. I would start by looking at door wiring.... I would put money on a pinched or rubbed through wire in the door pass through.... Quote Link to comment Share on other sites More sharing options...
2006IntimidatorSS Posted September 3, 2015 Report Share Posted September 3, 2015 Mine is doing the same thing except mine is doing it more often than not lately. Every time I turn it off, it just turns itself right back on. And man when it's hot outside, the heated seat is really not something I want to have on when I'm driving and it's 80 or 90 degrees outside. Not sure what the issue is with this, but I'm wondering what is making it turn on by itself. Quote Link to comment Share on other sites More sharing options...

EXGM Posted September 3, 2015 Report Share Posted September 3, 2015 Well going to have to figure out what's wrong with it. See my above comment... I would start but removing door pannel and checking all door wiring.... Quote Link to comment Share on other sites More sharing options...
Doughty08 Posted September 4, 2015 Report Share Posted September 4, 2015 My guess is the heater element itself in the seat is burned and causing the short. If u search heated seats there's pics and a lot of guys here whom have had this issue and that was the culprit. I had the same issue and pulled my covers off and sure enough burned elements. Good luck fellas Quote Link to comment Share on other sites More sharing options...

EXGM Posted September 4, 2015 Report Share Posted September 4, 2015 Thats what happend on mine. I don't understand how a short in the seat bottom would cause it to turn on by itself. I can see when you turn switch on and nothing happens or it gets SUPER hot or system turns on and off yes that most likely is a short in the seat element. I saw lots of those.... the fact it turns on by itself is a different issue... but I could be wrong... it happened once... lol. Quote Link to comment Share on other sites More sharing options...
Doughty08 Posted September 5, 2015 Report Share Posted September 5, 2015 Yea mine would cut on by itself and I wouldn't realize till it was cooking my butt and for the longest time I though I was just hitting it when rolling the windows down but then kept hearing the relay click and looked down and it was cutting on and off numerous times so I used the search button and sure enough led me to the elements where I found they were fried right where the wiring goes into the element itself. Real simple fix, I got my elements from work and wired them in and hasn't done it since. Quote Link to comment Share on other sites More sharing options...

Real simple fix, I got my elements from work and wired them in and hasn't done it since. Mine just started doing this today. I haven't driven truck in two weeks and now it's acting funny. When you replaced seat element did you check for codes? Quote Link to comment Share on other sites More sharing options...
EXGM Posted June 14, 2016 Report Share Posted June 14, 2016 Ok, Update. I played around with it and got my volt meter out. I checked resistance in the seat heater on the diver vs. passenger sides. The driver side show 3.5oms vs. 5.0 for passenger side. I was expecting to find an open but did not. It is spotty online finding info on the heaters. There are 10,000 posts about peoples not working but nobody about actually fixing them or how to properly diagnosis it. I did find something online that says spec is 1.5-5oms but I am not sure I believe it, so I am "technically" within spec. Temporally I have just unplugged the driver side but I think my next step is remove the seat and take it all apart to see which one is bad. I may just replace both for good measure. I am about 95% sure it is one of the elements but would like to confirm. If anyone has info to help me diag this I would greatly appreciate!
