I have a 90 vert, the driver side headlight motor intermittently failed to retract, then stopped retracting at all. I can turn it down by hand, it stays down. After it is raised, it will not automatically lower.

I tested the voltage at the plugs (awhile back) and found that power was available to lower the headlight. It tested the same on both the driver and passenger side.

I presumed the fault to be in the motor and bought a motor from another member, but is is apparently from an S4. There is a plug on the S4 harness that is missing from the S5.

I found this thread, it illustrates the difference exactly, except that I don't have the relay shown, just an empty plug.

Does anyone have an idea for a workaround? Or do I just need to find a working S5 motor?

Suggestions?

Thanks!
