Default Head light question

I'm a new member and this is my first post. I just bought my first Corvette. It's an 85', 78K miles, white w/red leather. Everything seems to be in good working order except for one thing. The drivers side head lamp goes up fine when I turn on the lights but when I turn them off it gets stuck about half way. I can get out and knudge it by hand and it'll go down all the way. Is there an adjustment for this? :confused:

Congrats on your new Vette; welcome to the Froum.

It's likely that your headlight motor gears are worn.

Eckler's & MAD have gear sets.

What is entailed in replacing them?

Welcome to the forum. :cheers:

Here is a great tech tip, it's the one I used to do both of mine. The first one took about 2 hours, the second about 30 minutes. They are both the same but on the first one I went very slow and careful until I knew what I was doing. As 65Z01 said, Ecklers and MADVET have the replacement kits and they are $4.95 each.

Good Luck and remember to be patient and take your time. :smash:

I was told by customer service at MadVet that there are no bushings on the 85' Vet and that it has to be the gears that are the problem. Is that true?

Oops, I didn't pay attention to your year :bb If it's the gears, check Ecklers P/N: 39975 $39.99. Make sure you check the gears before you order new ones.

The project isn't too bad and doesn't take too long to complete. If I were you I would seriously consider spending the extra money to replace the gear set with the brass "upgrade" set. The original gears and the $ 39.95 replacement set are both nylon or some similar material and will likely go bad again before you are ready to tackle this project again.

I replaced both sides of gears in less than 2-hours on my 85. By a Haynes manual for that car casue you will need it to help pin-point problems and help with repairs.
