Hello and welcome to JustAnswer. My name isXXXXX cigarette lighter is protected by the #18 20A fuse that is located in the Power Distribution Center. Check if the fuse is not blown. If it is OK, check if you have +12V at the cigarette lighter socket with a test light connected to ground. Your heated seats are controlled by a Heated Seat Module that is located under the right front seat . It sounds that this module detects a problem within its control circuits and then inhibits heated seats operation. It is possible that a heated seat element is defective. This system is supposed to be diagnosed with a scan tool. Without using a scan tool we can only guess what is faulty, but it is not a cheap way to replace parts by guesswork.
Is this fuse located in the trunk or under the hood of car ? And the fuse that i checked in the trunk # XXXXX is not blown and is okay. Is there a fuse for the heated seat control also ?
The PDC is in the trunk, next to the battery. Yes, there is a fuse #5 ( could be 30A or 40A) that supplies power to the heated seats module, but I am almost sure this fuse is OK.
Hello how are you doing and thanks for all your help. If it is the module under the seat is it very expensive to get reapired ? And does this module control both seats ?
Thanks, XXXXX XXXXX fine it is a nice sunny morning here. Yes, this module controls both seats. It is hard to say whether it will be an expensive repair or not. I have never said this module is bad, any repairs with the heated seats system should start with diagnosing this module with a StartScan or wiTech scan tool.
