I have a question regarding the rear defrogger. When I turn my car on and its cold enough the rear defogger comes on automatically and I dont want that to happen because its rare that the car has snow on it since I park in the garage. I notice it when its cold enough when the center console display says that there maybe ice outside. I dont know if this can be changed in the computer system on the car or not but I thought I would ask. I called the dealership and service told me that they didnt think so. I have a 2011 Regal T06. Any help would be appreciated.
