I have had several power sliding door problems with my 2001 Grand Caravan. Motors, latches, etc. Anyway this year the issue is that the power sliding doors do not work using the buttons inside the car. I seems to be related to the temperature. As the weather got colder, first the buttons in the overhead console wouldn't work intermittently, but buttons next to doors still would. Now (colder) neither the overhead console or buttons at the door work. Using the remote key FOB works fine. Any advice?
