Problem with Headlight-C4
About a week ago, I was driving my 94 C-4 at night and noticed that when I turned off my lights, the driver side headlight folded fine, but the passenger side light stayed up. After turning my lights off and on several times, the passenger light still stayed up. About 30 minutes later, I turned my lights on and off again and both lights closed. There no noises coming from the lights at any time.
Has anyone else ever had this problem? If so, how did you fix the problem?
Thanks for your help.

Headlight repair
Even through your headlight is not making any noise the motor is broken. Usually the motor will continue to spin for about 20 seconds after engagement but mine did a combination of noise and no noise. I went onto ecklers and got a rebuild kit for the head light; three little plastic rollers and a new gear, cost $10.50 i think. Then you have to dive into getting that headlight motor out of your vette, and then taking it apart and replacing the bad inards with the new stuff from ecklers. search this forum for a how-to, to get a step by step on how to go about this. Have fun

it sounds like the bushings are gone. It is a very easy repair and very inexpensive. You can get the bushings at (don't laugh) Home Depot for about a dollar. The best way to repair it is to pull the entire headlight assembly off the car. The bucket and motor all come aff together. Then it is very easy to work on a bench. The step by step instructions are in the tech tips section of the forum and also Corvette Fever has a easy to follow "how to" on the subject. A search in this forum should bring up even more info including the part number for the bushings at HD. good luck, it's not a bad repair at all.

I upgraded mine to the brass gear and solid bushings but i did go to home depot and they do have them. Best way is to take the whole light assembly off the car. Lay it on a towel on a table to work on it. It only looks hard it's not.

It is a lot of disassembly, once you actually get the specific area apart you will find cyrstalized packing material which you must remove and then replace with three Delrin bushings. Unless the main gear is trashed you don't necessarily need the brass gear that would be your choice.
Don't under any circumstance manually force the headlamp assembly to move/rotate. Doing this will spin the splined shaft and once that happens your in for a new motor about $280. One of those things you learn the expensive lesson.
Here's a picture of what you'll be looking at when you get there. Look carefully at the gear and you can see the three Delrin bushings in place.

Although it's most likely the bushings mentioned in these posts it could also be the headlight motor relay. I had one go out on my 89 and the symptoms were one headlight stayed up and the other opened and closed normally. I'm not sure of the cost now but in 1994 the relay was $120.
