Hello all, I thank you in advance for any guidance you are able to provide. Recently, my heated seats stopped working. When I pressed the either the driver or passenger seat heated seat button in my 2003 Jaguar S-Type, it turns red for a second or less but then it immediately goes off. In addition, the door lock button also does not work anymore. However, interestingly the warning light button, and the other buttons on the module does work. I had two different shops check the fuses but they both stated that the fuse was not blown. What is my next course of action to trouble shoot the problem?

 

I'd stare at the Electrical Guide hoping to see a relay or something to suspect. Free download with JTIS or on JagRepair.com - Jaguar Repair Information Resource

 

Thanks for your help.
