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

I think there are 2 relays for those.... Worse comes to worse and if you can live without cooled seats an aftermarket heater kit is about 50 bucks

Just pulled the pass seat out and discovered It is the plug and the module that shorted out or burned up.

Going to order new delphi connectors tomorrow, and give it a whirl.

Did this fix your issue. i have a 2009 Avalanche with heated and cooled seats. u turn it on and u hear a click and nothing happens.

Yes this did fix my issue, I purchased the new housing connectors for about five bucks from my GM dealer. They also sold a full wiring harness for about $130 (just in case). It was hard to remove the wires out of the old terminal that was burnt up due to the plastic being melted. make sure to take pictures or notes on the colors and where they go do not mix them up.

But now I have heated and cooled seats. ?

Need help please, same issue with my 2014 GMC Serria, heated/cooled seats: lights come on and stay on in heat mode, fan motor kicks on and runs in cool mode but no heat in either remote or keyed start in both seats, checked fuses, even tried each seat individually with only the back or bottom heater turned on, still no heat.
