I have a 2002 Grand Prix GT and I have a really weird issue. This happened before but resolved itself within 24 hours but this has been lasting for a couple days.
The interior lights don't work when the doors open, not even at night or when the manual switch is used. The radio doesn't work but a Humount illumination mount does (wired to illumination wire I think radio is wired to main power wire). The window/lock controls don't work inside the car but light up at night, remote unlock/lock doesn't work. Power mirrors do however work.
