yes, we were right. it was the switch. got a new one under warranty and took the bad one apart to find water had gotten in and ruined it. these switches are not weatherproof. i will be putting a small bead of silicone around where the barrel is crimped into the switch body to seal it on both when i put everything back together. i also got a spare direct from barker manuf. along with the hex drive tool for manual operation. cost for both with shipping was $30. did some more research on the switch and found them available locally at an automotive electrical repair shop that does auto, truck, construction and farm equipt. made by cole-hersee p/n 55046. for you technical guys its a: DPDT polarity reversing momentary on-off-on forward-reverse toggle. wow, what a mouthfull. they also make a weatherproof boot thats much more heavy duty than the oem and seals better. they even come in different colors. cost on that switch with boot is about $15. i'm thinking i might also add a small o-ring over the barrel on the outside of the coach to help the boot seal even better. hope this might help someone else.........mjf
