Sundancer, no switch in box. The motorhome is plugged into house power, 110, and I switched on the A/C and it worked. I didn't leave it on for fear of it drawing to much current. Could it have some wires mixed up?
The wires were reversed on the toggle switch for the heated mirrors and I've heard of others having various wires mixed up.
