I have a 1990 Corvette that the headlights will not open how do I check out this circuit I have jumped the motors with a jumper wire they both work


Do the motors have enough torque to open the headlights? Have someone turn switch on in car and with hood up see if u can hold manual wherl back with hand slightly. Be carefull. Dont want u to get hurt, just want to check if motor has enough torque to lift headlight. I suspect the motors are week, and you can buy new ones or get some from junk yard. I hope this tip helps your situation and saves you money. Have a good one.

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.

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.

1987 corvette, headlight goes down and motor continue to run


Check the sensors that tell the relay to shut off when the lights close down all the way. This is a fairly common problem especially if this has never been replaced before.
