Late model Fiero become a one eyed wonder? Most of the time, the fix is relatively simple and straight forward.

Remove the headlight motor assembly from the car, and disassemble. Remove the shaft and nylon gear carefully, and push the gear and shaft apart to open it:

Clean out the waxy crap that has no doubt turned into powder by now. It's this material that causes the nylon gear to turn the shaft, which in turn operates the arm that lifts the headlights. It's designed to give way and prevent stripping of the gear(s), but unfortunately, it also gives way and prevents your headlights from working in time. If your nylon gear is trashed, this isn't going to fix it. You can obtain an upgraded hard anodized aluminum one from Rodney Dickman: it's much stronger than the original. You will need to obtain 3 of the correct sized bushings to insert into your nylon, or aftermarket aluminum gear. I machined mine from Delrin stock at a buddies shop. The dimensions I arrived at were .460" long by .480" diameter for a snug fit. It turns out Rodney sells the exact same thing, also made of Delrin if you don't have machining capabilities. Buy the gaskets as well while you're at it, the parts are cheap.

Now install the bushings, and push the assembly back together. Grease liberally, Reassemble, and reinstall:

Should be good as new! This completes yet another mini-tutorial on late model headlight repair. It's cheap and easy, so don't be left in the dark!
