Put a corvette headlight motor together


I wrote a guide on the Corvette Forum for replacing the headlight gear, which involves taking the headlight motor apart and putting it back together:

1985 corvette headlight close but wont open


I did mine about 3 year ago, C4 headlights are electric motor driven. Clean the contacts, if they are clean, you will have to replace the gears, it's really not hard, just be sure to clean everything as you re- assemble the motor drive. I used synthetic grease. The drive can be unscrewed from the housing and then changing the gears is easy. Most gear sets have directions with them. I got mine from Corvette Central. (about 50 for the set, replace both gears) Be sure to remove any debris.

I have 1990 vette have rebuilt headlight motors and a new headlight module , but headlights still go up and stay up in sunlight


Not a Corvette expert, but I don't think sunlight would have any effect.
The motors should close the doors when you turn the lights off regardless if it is dark or not.
Are the headlights staying on, or just the doors staying up ? The up position is the default when something is wrong, so I think it takes voltage to close them.

You will need to rebuild the headlight motors. You can buy the headlight motor rebuild kits with full instructions from ZIPS.com or any of the online Corvette restoration parts suppliers.

When the headlights go up they dont turn on and when they go back down the one on the passenger side clicks really loudly.


Hello, my name is Ben. It's possible that both bulbs have burned out. Have you verified voltage going to the plug where it goes into the back of the headlights? As for your right headlight clicking. The most likely cause is the plastic gear inside the headlight motor is worn out. The gear will need to be replaced, or eventually the motor won't raise or lower the headlight. There are brass gears made as an aftermarket part that are vastly superior to the stock GM plastic gears. I hopes this helps. Feel free to ask any other questions if you need more information.

Headlamps are stuck in the up position. There is clattering, like a motor gear slipping, whenever lights are turned on or off


Hello, my name is Ben. You may know this is a very common problem in Corvettes. Chevrolet uses plastic gears in the headlight motors and the gears fail over time. You headlight motors are going to need to be rebuilt. There is a company that makes a brass gear to replace the plastic gear. I'm not sure if you are wanting to do the work yourself or having it done. If you are mechanical and feel you can accomplish the repair, I can send you the procedure.

Corvette Headlight Motor Problem


Corvettes have a gear box on that motor. It has plastic gears in it. You probably have a gear stripped in that gear box, that lets the motor spin free. You can get repair parts to repair it, or replace the whole motor and gear box. Its an easy fix if your handy. Read all the instructions before you start.
