The headlight that is!

When I turn the headlights on the driver comes up fine but the passenger only goes halfway if that. I can get out and turn it into position by hand but then in falls back down. Is this a motor issue? Gears, bushings, vacuum? I have no idea what is involved with these headlights or how they come apart. I looked in the headlight sticky but none of the pictures showed up.

Thanks in advance.

All the pictures in the headlight sticky were pulled by Schrade after he got banned. It sounds like bushings. You can get these at Home Depot for a lot cheaper than one of the Corvette suppliers. I have not had to rebuild mine so I do not know what entails this. Others will chime in that have completed this process. I have heard it not hard just a little time consuming.

I bought some bushings on ebay and they worked perfectly, I was too lazy to take pictures though. The key is taking as few things apart as possible, but it is a super easy fix. Don't forget to put the movement limiter on, or you will repeat one side twice. Total cost was around 3 bucks. Do both lights even though one still works, it won't work for long, the bushings turn to dust.

Do you have a part number? How do I know the ones on ebay will fit?

Also if anyone has pictures it would be helpful. Thanks!

I would say no, the bushing disintegrate, the gears seem to stay fine. Here is my quick and easy guide

1. remove assembly from hood, mine had 4 nuts and and electrical connector.
2. Use a punch or something else to knock the roll pin loose that holds the motor to the frame, don't knock it all the way out if you can help it.
3. With the assemble upside down, loosen but dont remove the two torx that hold the frame to the finished headlight so you can get to all the bolt that hold the motor to the assembly.
4. Loosen the 3 torx that hold the motor to the assembly now that you can get to them all.
5. Make sure you look at the spin limiter how it goes on before you pull the motor off, also notice how the wire is routed so you can put it back the same way.
6. Back the keeper bolt off, then unscrew the drive shaft a couple turns, don't take it all the way out or a new motor you may need.
7. Remove the screws holding the cover on and pull the thing apart.
8. Dump the dust out and clean the whole thing up.
9. The new bushing will fit tight, get them started at and angle and tap the thing back together.
10. Reassemble the whole thing minding the wire routing and the limit stop.

I believe that is not the part you need. Those are bushings, spacers. You need the gear.

The good news is Ecklers has them. The bad news is when I bought mine they were $5 a few years ago, now the same part is $25….wow. Ecklers says GM does not make it anymore so other suppliers. The gear is also made in metal which never wears out but is more expensive. This is the link for the nylon gear. I might look around to see if there are any other options to buy at better price…..maybe not?

I recently went through this, and its not too hard of a job, it only took me about an hour and a half , but make sure all of your linkage is connected right and not loose especially the roll pin, cause thats what was the underlieing cause of why mine wouldnt work. Also, be carefull with the gear if you do decide to replace it, it doesnt take alot of force to break them.

Theory and diagnosis always works best first. Take the headlight apart and look and find the problem. Then go buy what you need. More than likely you'll find the plastic gears are worn.
