2010 GMC Sierra Denali - Cooled/Heated Seat Not Working? - HELP..

Nvd · February 3, 2014

Truck: 2010 GMC Sierra Denali

Engine: 6.2L V8

Milage: 104,000km

AWD

Issue: Front driver side Cooled / Heated Seat does not work/turn on.

I noticed this about a week ago, normally when i turn it on i hear a "click" and then it gets nice and toasty. But now i do not hear any click and it does not work at all. I tried just the back or the cooled and nothing. The lights stay on, just no heat.

The passenger side works fine.

I have not had a chance to look at a fuse or anything, but wondering if anyone knows why this would happen and how to fix it?

Thanks in advance!

Nick

I would start with the fuse and then the relay.

I will try to locate/check the fuse soon and see if this is the issue.

If it is not the fuse, any suggestions on my next step?

Thanks

there is a module under the passenger seat that gets carbon build up from the connection. sometimes if you can get you it you can clean the connections.

That may be, as yesterday when I was in line for a car wash i was playing around with the button and normally it clicks when it turns on and that has stopped but yesterday it seemed to click on again and was starting to get warmer, I has it on the high setting but seemed to heat up as it was on the lowest setting? then today it didnt work at all...

Well, I still cant figure out why this isnt working..

Any suggestions? or how to solve this issue.

hzhardy- whats the module look like? I look under the seat and all i see is plasitc covers. Id like to check the connections. But could the connections under the passenger seat effect the driver side seat?

Thanks
