Fiero headlight "open" knob rotating

Hello,

My Fiero headlights were both stuck up for quite a while (would turn on and off quite fine), and I did not have time to thoroughly check what was wrong.

Today, I looked at the troubleshooting in regards to my problem, and I tried the first of the list by checking the 20 amp taillight fuse. To my surprise, it was blown. As I was replacing it, some small sparks were made as both of my lights were going down! Then the problem was that I heard a grinding sound against my hood. I quickly opened the hood to see that the left "open" nob on the headlight was rotating, despite the fact that both of my lights were now down! I turned on the headlight button, and my left light would go up, and my right one would not. I quickly disconnected the isolation relay to make the grinding stop as turning off the headlights wouldn't stop the knob from constantly rotating. I tried connecting the relay again and it would still rotate.

I suspect that my right light probably needs its gears replaced, but I have no idea why the left knob is acting strange despite it being able to go up and down fine. Although the left relay is just a few months old, does this sound like a relay problem?

Yes and it got stripped gears from having bad (dirty) points. The
motor is supposed to stop when it reaches full up or full down. If
the points are not working, the motor keeps trying to move and puts
a lot of force on the gear. Eventually, the gear strips.

Instead of disconnecting the relays you could instead unplug the single wire that connects directly to both headlight motors.
