headlight motor troubleshooting - ZR-1 Net Registry Forums

Hey, so a friend's ZR-1 is doing the cyclops thing. The passenger side light doesn't go up intermittently.

But here is the odd part. It doesn't make any noise either, the motor doesn't spin or anything. Sometimes it will go up partway, though the motor sounds rough/clunky when doing so. And if you open it by hand, it will generally close when turned off.

I don't think that would be the bushings, as the motor generally spins away.

I put a voltmeter on the electrical connector to the motor (disconnected the motor to do this), and it spikes up for a second. It seems to do that every time, and does the same thing on the working driver's side. So that makes me think the controller is working properly, but that might be a lame way to troubleshoot it.

Thoughts?
