Tonight when I turned on my headlights, the passenger side didn't raise up. I hear a clicking sound at the relay whenever I activate the switch. To test the relay, I switched the left and right headlamp relays and nothing changed--ie, the driver side works, the passenger side doesn't. I sprayed the relay contacts w electrical cleaner as well.The fuse for the headlamp motors was also replaced, with no change. Next, I checked the wiring connectors around the motor. I pulled them all apart, sprayed with contact cleaner, reconnected--again, no change. I also loosened the ground wire aside the motor, sprayed and retightened--no change. Re: juice, I get juice on one wire of the three in the large white connector going to the headlamp--a gray wire. Nothing at the green one. There are 2 other connectors ( w 2 wires each) going to the lift motor as well--one black and one white. I get juice in the white connector, but nothing at the black. Should there be juice there? Is one for lifting up and the other for stting down the headlamp? Any ideas about what to look for and where? Is there another ground wire somewhere at each bucket or is there just the one. Prior to this, the headlight lifters worked perfectly.
