2001 Olds Aurora 3.5 V6. All power windows, door locks, mirrors, fuel door and fuel door switch do not work. All doors are affected by this. Also the clock in the radio does not turn off. Checked fuses and disconnected battery which did not remedy

i would check the two orange wires at the ddm for power and there are two grounds black and black white. if those are good sometimes the ddm messes other things up through the body control network, not sure how you would test that though

I had the same problem with my 2001 Aurora V8...it lasted a few months and all of a sudden everything was working. Same thing - I checked fuses and even had a garage look at it. No one knows...mystery. I know that doesn't really help, but at least you can keep your hopes up that it will all of a sudden work again like mine. It'* been back to normal for about a year and hasn't messed up.
