Ac compressor isn’t getting power. Both white wires from the AC switch inside the cab to the AC relay are hot. I’m not sure that both are supposed to be hot like that..anyone know? I’ve swapped relays, still nothing. Fuses are fine. I’ve jumped the low and high pressure switches and it does nothing. Back story- a week ago compressor didn’t come on for about the first hour of operation then worked rest of day. Second day same thing, 1 hr or so. Third day it never came on and hasn’t since. Freon pressure etc checks out to be fine. Any ideas?
