Recently I had an issue with a tempermental headlight
Here 2 years later the problem resurfaced. Turns out
This gear was from the Fiero Store and I believe it too be inferior plastic. It has since lost it's overall round shape and even the teeth are no longer straight axialy. they sort of curve (concave) from one side of the gear to the other. I look forward to my metal replacements from Rodney Dickman. ![]() |

I picked up the metal replacement but after reading some things on it, the gear might not be my problem!! My parts car has a good unit the passanger side that I need so for a quick fix I am going to install it on my car and then I will take apart the broken one and get it rebuilt and put on the shelf until it is an issue again!! |

It's not easy to see but the plastic has sort of undergone some transformations in the past year. The largest diameter near the edges of the gear measures 2.115". The smallest is 2.055". Here's a bit better perspective. Cheers |

Wow....that material is not very stable is it? It looks warped.
I've said it before, one of the problems that plague us Fiero owners is the bad quality aftermarket parts out there. Not so much the Fiero Store or Dickman stuff but the parts at the local automotive retailer. We do our part but the components let us down. Bummer. The Dawg |

Obviously you are talking about another matter of your own here...? Dawg. I will try and hang on to this gear for a show and tell at the next gathering. Yes it is very deformed. More even than the picture shows. Oh and some teeth are also chewed away. |

Yeah...was talking about the issue I have with mine...gotta check the relay then the gears but it will go up and down with the hand crank so it atleast narrows down the problem!! |

Charlie - you say your headlights go up and down via hand
crank of the motor but also that the motor runs continuously when plugged in...? Are you saying the motors are on and just stuck when plugged in or on and rotating when plugged in? If on and rotating - then direction will tell you what what part of the circuit to consider. ![]() and that likely the main gear is stripped. |

Charlie - sorry did not mean to confuse you but your description of what is happening may require further explanation for me to totally understand your headlight motor predicament. Brian - I already contacted Rodney for a gear and a spare - in case the other motor decides to pack it in. But thanks anyways. |

Decided to open the left hand motor to check on some free play - It didn't seem to affect the performance except for the occasional delay going down but with new gears coming thought why not. Turns out the rubber bumpers in the main gear were completely obliterated. Other wise the system was in pretty good shape.
Talk about lucky. As I was cleaning up, I pulled the electrical contacts out and off the rotor, one of the brush contacts came off. |

Charlie - I am curious - how did you re-secure the main gear retainer?

Then I took a sharp chisle and hit the lip just above the retainer clip on the shaft on four sides/corners. This expands that rim slightly and holds the retainer in place I google videoed the process...Buddy Craig has 7 posts showing the rebuild process I found very helpful!!!

My plan was to center punch the retainer. Either way I suppose.

Wow....chewed or what? It appears as though the motor has not stopped in time and cut the teeth right off.
I would check the limit switches to make sure they are in good shape and in the right place. The Dawg |
