If the radio is ON and you turn OFF the ignition key, does the radio immediately turn OFF ? If so, it's most likely one of the front door jamb switches that's failed. Each door has one located at the bottom of the latch and you have to remove the door panel to access it. The two front doors will turn off the radio when they're opened. The rears do not. It's usually the driver's door switch that fails first, just due to the amount of use it gets. Be careful when ordering replacement switches because there is a different orientation for left and right sides.
So my door ajar light is always on and sometimes on the real cold days that we have had it turns off and stays off until it warms up and then its back on, what do i need to check?? Any help would be appreciated thanks....
