[QUOTE="ORVietVet, post: 23862, member: 9438"] The symptoms you describe are classic electrical/ground problems. If the wiring from the ground spot is not corroded inside the insulation and if you follow the wiring to the inside and to the actuator and there is no rub thru of the wires, then the switch or actuator are suspect. I hate shooting the parts cannon at any problem. Your problem is intermittent enough that trying to track voltages and grounds during the problem, is a PITA. IMO, if what I just laid out is all good, then because of the rust build up I see, I suspect the actuator but I would pull that switch and do your best to make the switch malfunction. [/QUOTE]
