All at once the power door locks, power windows, interior lights, and rear air compressor/air suspension quit working due to some sort of electrical problem. The interior lights finally started working again after about 3 months of not having any, but were on all the time and had to be shut on and off with the switch on the ceiling by the power sliding door switches, and then just recently stopped working again. Also the Power windows have worked a couple times for one day and then quit working again. I think this is due to standing water that leaks in on the passenger side where all the wires and harnesses are at and corrodes the wires because i have checked every fuse and relay and all of them are working properly and no blown fuses.
