The gears that raise and lower the headlights are made of plastic and are a known issue. Many companies make brass replacement gears.

You have major wiring problems or bad switches. I would replace the headlight switch before testing for any thing else. if it's the switch you got lucky, if not, it will be a lot of wire testing.

    No--there is a module behind the passenger side headlight and it often goes bad because it is poorly sealed. Expensive to replace. Google 1984-2004 C4, C5 Corvette Headlight Control Module OEM 16521297 16523917

SOURCE: How do I remove the door panel on my C5 Corvette.

The problem is with the door switch. It should be mounted on the door post. You either have a bad switch or a broken wire.

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.

CORVETT POP UP LIGHTS Hi I have a 1977 corvett stingray. Do you have any ideas as to get the vacume system on the pop up lights to work correctly. They sometimes will go up, 1 at a time but very


The first thing , this system works on vacuum there are vacuum lines that run from intake to storage can or cans then to light switch inside car then back out to headlights,

i would first start by starting the car and listen for vacuum leaks, you may want to follow the vacuum line form the motor checking for splits or cracks in the lines, listen around can, this can sometimes rusts and leaks vacuum, this can or cans are intended to store vacuum and use it when needed, if they are leaking then the lights will work slow until there is enough vacuum to open them, this goes the same for a bad vacuum line and light switch, the light switch is a two part switch, one part supplies power to lights and the other part is vacuum to open lights.

you will need to listen for a vacuum leak inside the car at the switch, (headlight switch) .

Make sure all lines are good and have no leaks, you will need to make sure the hinges to lights are free and not binding up.

The interior ligts on my 1989 corvette coupe stays on all the time


make sure the interior light switch is turned off so they only come on when the door is opened(this happens alot),the next thing is it could be a door switch that has a problem thinking its open.you could also have a headlight switch that has an internal problem like a short that is allowing power to the interior light wire circuit of the switch causing the interior lights to stay on.

Headlight problem with my 2000 Corvette. Sometimes when I start the car both headlights pop up and turn on and the switch will not turn them off. I have to turn the engine off and turn the light swith on...


Do you know how to test automotive electrical circuits ?
When the headlamp switch is turned to the HEAD position, battery voltage is applied to the headlamp opening door actuator control module through CKT 103. The LH head lamp door opens when battery voltage is applied to the LH headlamp opening door assembly through CKT 576 and ground is applied to CKT 577. The RH headlamp door opens when battery voltage is applied to the RH headlamp opening door assembly through CKT 578 and ground is applied to CKT 579. When the headlamp switch is moved to the OFF position, battery voltage is applied to the headlamp opening door actuator control module through CKT 306. The LH headlamp door closes when battery voltage is applied to the LH headlamp opening door assembly through CKT 577 and ground is applied to CKT 576. The RH headlamp door closes when battery voltage is applied to the RH headlamp opening door assembly through CKT 579 and ground is applied to CKT 578. Battery voltage is constantly applied to the headlamp opening door actuator control module from the HDLP MOT L MiniFuse® #4 (CKT 2940) and from the HDLP MOT R, MiniFuse #3 (CKT 3040). The headlamp opening door actuator control module is grounded by CKT 150 through Splice Pack #100 to G102.

Headlamp Doors Do Not Close
Install a scan tool and go to the BCM input display.
Monitor the headlamp off switch status.
Turn the headlamps on and off.
Does the scan tool indicate the headlamp off switch inactive and active?
--
YES - Go to Step 4
NO - Go to Step 6
4
Disconnect the headlamp opening door actuator control module connector C1.
Connect a DMM from connector C1 terminal D to ground.
Measure resistance to ground of circuit 150.
Is resistance within the specified values?
0-2 ohms
YES - Go to Step 5
NO - Go to Step 9
5
Connect a test light from the headlamp opening door actuator control module connector C1 terminal C to ground.
Turn the headlamp switch off.
Does the test light illuminate?

C5 daylight running light and front directional does not work , but they work when the lights are on. strange.


Sounds like each bulb has 1 bad element. Unusual, but possible. Those bulbs are tricky to change but you can do it.
Turn your switch on and turn on the headlights. While they are still up, turn off the switch so that they will remain in the up or open position.
Next to each headlight assembly, you will see a rubber hood stop that can be easily removed with open ended wrench. With those stops off the car, it is a snap to reach down, next to the headlamps to the back of the parking lamp socket and remove it by turning conuter clockwise. Replace with the correct amber bulbs (available at any auto parts store) and your problem should be solved! Note.......be CERTAIN to check all fuses 1st. Good luck!

1985 Fiero: headlight doors will not open


Your headlight motors are bad. Pre-87 cars had a terrible problem with this, upgrade them to the 87-up style. Firebird/Corvette motors are the same.
