When driving along an inclined unpaved road without accelerating, and even sometimes braking a bit, the van suddenly stalled. I have noticed it has something to do with the lamps as, when the vehicle is about to stall, lamps fade.

All off a sudden ac stopped working an blowing hot air the Freon is full plenty of pressure but compressor won't kick on I checked the pressure valve sensor on the line jumped the plug with a wire an compressor still doesn't work
