AC won't shut off
1992 Explorer, 4.0L 4WD.
With a correct AC charge the compressor cycles on and off with the control switch in OFF. The same as it would with the switch ON. I think there is a sticking relay somewhere. I completely rebuilt the AC system excluding the evaporator many miles ago. This is really a problem in cold weather when I don't want the AC running. The compressor generally remains unpluged.
Also the vents will occassionally blow hot air as if the system is shutting off. A few minutes later cold air comes back out.
Where is the relay located that powers the system?
