Low Mileage
Behavior: headlight motors go up and down, but opposite to switch position. With switch off, headlights are UP, with switch in middle or on position, headlights DOWN (headlamps are on).
How i got here is a little circuitous, and doesn't help my troubleshooting. But may make more sense to you guys.
I did the diode replacement on both motors to correct a lack of motor operation - previously would only return to down position, no up operation. Checked fuses, ruined one in process, ordered 2 from MB... Fuses seem to be OK.
When i first put everything back together, didn't get any motor movement at all. Turned the headlights to 1/2 up position, and with key movement, they would cycle down and back up. And STAY UP.
When I started the car, the headlights would cycle normally with switch operation for 2 full cycles, then stay up. I continue to get this behavior - motors stuck in the UP position, no operation from switch.
HOWEVER, if I manually put the motors in the midway up/down, start the car, i return to the headlight motors operating both up and down, but OPPOSITE the switch position.
I thought I was crazy after writing this, so went back out and checked again. First, a full up/down cycle (correctly with switch) and headlights staying in the UP position, shut off car, place motors in the midway position, restart car, and get full UP/DOWN, but OPPOSITE the switch.
Any suggestions? Did i screw up the diode replacement, or perhaps have relay gremlins.
thanks! Chris
