Headlight issue
Ok I have 87 c4. Haven’t had the car long and just tracing down headlight issue. Drivers side was stuck up when I got the car and I replaced the relays and they worked perfect. But now drivers side will only flip over a little over half way and appears to get stuck but goes down fine when I turn headlights off. Can anybody point me in right direction to figure out the cause ?
thanks in advance. I’m still new to the corvette world and I know these headlights can be problematic

Maybe it's getting hung up on the motor wire.
Open the hood and try to open them and see.

If the gears or bushings are worn you will normally hear the motor running for a short time after the light is fully closed or open. The motor should stop immediately after the lights are in the fully open or closed position.
Can you fully open the light by turning the **** on top of the motor? This should always work to open or close the lights.

I heard a little noise when lights were turned on like maybe it was still trying to open
If I tried to open manually with them already turned on I would get a resistance almost like the motor resisting and it would make a buzzing noise

Sounds like what Firebundle mentioned, then.

Check to be sure the housing that holds the light bulb is not hitting the opening.
IF you push it ( help it) while opening / closing and it goes, usually the gears. Or like said earlier - motor keeps running , it's gears.. likely

I know it’s not catching anywhere but I will check again to see if I can assist it while opening before I buy the kit to fix it.
I appreciate all the feedback Like I said before, corvettes have never really been my thing. I just kinda fell into this one so I’m having to do a lot of research and figuring things out. This forum has helped a lot

The car you have is a lot of fun and actually a nice ride.
I have a modded 85 with a 383 / 6 speed, it's a blast..
The rebuild kits are not hard and there is a lot of videos on how to do it. Just clean the old lube really good and re lube..

Yes it sounds like the bushings need replacement. I have yet to see a gear being torn up, usually just the three pucks are destroyed. You can buy replacements at any auto parts store. They are Dorman part number 74410 listed as “window guide assortment”. Really it isn’t an assortment it is just the three nylon pucks you need.
I admit I do have a pair of gears just in case but have never needed to change the gears. The pucks are just ground to dust. There are a couple of threads on the forum that will walk you through the replacement process.

I would replace bushings AND gear. See my thread I posted last night on my 89. The bushings were just fine, but the gear had one big crack across it, and two smaller hairline cracks you could barely see. Pays to do the job once.

Fasttimes1971 you are absolutely correct! 85-87 did not have the delrin bushings, they only had the gear sets to change.
Any of the corvette suppliers (ZIP or Ecklers) will have them.

They're vinyl for a reason. They're designed to wear, rather than wearing the worm gear of the motor.
With a brass or aluminum gear you stand a chance at destroying the worm gear over time.
But if you're not driving at night all the time and turning the lights on and off more frequently you should be okay with the brass or aluminum gears.

I used bearing grease when I replaced the gears.
Seems like that white stuff likes to turn rock hard over time.
