What if a 2008 ford king ranch expedition AC switches on in the rear all the time, but no air from the front ones. any reason for that? also there are times when i am driving and then the front ac unit cycles on, once on it will not stop unless i turn engine off, then may or may not start again. lately it usually cycles on when i drive over 60-65 mph or if i hit a bump at the right spot. the back ac unit turns on all the time.
Someone told me it was the ac switch.
