So today on the way to pick my kids from daycare, the driver side seat heater decided to turn itself on full blast! After turning it off, a few miles down the road it turns on again and again and again. don't know why haven't changed anything, other than having the truck at the stealer last week for the rear doors not unlocking. I called the stealer to report the issue and the service manager said somethign about teh control module that works the remote unlock would cause this problem. Please advise?
