Hey guys, I need some help. The other day, after I turned off my head lights, there was a loud buzzing sound coming from my left headlight assembly. I popped the hood and saw the motor continued turning after the headlight was down making the awful sound. I fiddled with turning the **** - figuered it was stuck somewhere but didn't help.

Any suggets to rid this fluke?

Thanks!

(If I have to I'll bring it to the dealer...)

 

Bad gear. Get a brass one...

Brass Gears

 

Yep, but doesn't take long to fix (if you don't include the 24-hr dry time for the epoxy assuming you have the 'glued' housing). Good luck! Here's some 'structions:

Ditto the two post above - do it yourself, directions on gear web site, not very hard to save money here. There are two methods:
1. Repair without removing assembly (don't do this one - harder for a first time repair)
2. Remove entire assembly and repair/replace (go for this one, much easier for a first time repair)

Since your car is a 2000, the earlier year models have 3 screws to open the gear assembly housing, the later in the year models are sealed and will have to be popped then epoxied back together

 

Rodney Dickman and make sure you get the updated bracket as well he has made, otherwise you maybe fixing it twice as the cover can pop off.

 

Hey that link doesn't work...could you send me another? And what supplies do I need in addition to the brass piece?

Also it's a 99, if that differs from a 2000?

By the way - Thanks for all your help guys.

 

The Headlight Motors Originally Come With Plastic Gears You Need The Brass Replacement Gears Which You Can Get From Ecklers Or Zip Or Even Mid America

This link has all the info you need. It also has a link to the above link that doesn't work. Your profile says your car is a 2000, you need to be sure. All 99's had the bolt together housings on their motors (unless they have been replaced by newer ones at some time), and the 2000's were the dividing year. The early 2000s have the bolt together type, and the later ones have the glue together.

The bolt together type are preferable because some people have had problems with the epoxy not holding when they re-do theirs. I did mine about 4 months ago and they have been flawless. I would highly recommend getting the kit from Rodney Dickman (see link above) because he offers a brace with his to keep the housing from coming apart. Just click on the electrical tab and scroll down to the corvette headlight repair.

(Being a 1999 your motor should have three screws holding it together, so it will not have to be pried apart, no 24 hr drying time)

I recently performed this repair on my late model 2000. When I attempted to remove the motor w/o taking the assembly out the last of the (3) bolts holding the motor in hit the hood hinge preventing its removal. Also, when you remove the Motor/Actuator and separate it from the linkage the headlight unit will drop and lining it back up with the linkage will be difficult. I followed the directions in the GM Service manual and it was not that difficult. It took about 30 minutes each for removal and reinstall the assm. And about 10-20 minutes each for the removal and reinstall of the Motor/Actuator (not counting epoxy set up time).

I suggest the following:

Put the front of the car up on ramps (rhino ramps work w/ a couple of 2 x 4’s placed at the leading edge).

Remove the HDLP Maxi Circuit breaker #54 located under the passenger side foot board.

Disconnect the headlamp wiring harness for the appropriate headlamp.

Raise the headlamp manually.

Remove the headlamp bezel and headlamp cover. (Lower the headlamp assm. slightly to remove the two rear screws from the cover)

This is the ramps come in. Remove the front bumper close out panel on the effected side. This panel is directly under the headlamp. There are five 5/32 screws – easy to do. Don’t worry about the brake duct you can work around it.

Have a helper support the headlamp assm. Remove the two (2) bolts mounting the headlamp bracket to the frame. Then remove the three (3) nuts mounting the headlamp bracket the stud plate. Removing the three mounting nuts was easiest from underneath the car, and the two frame bolts can be done for up top.

Carefully lift the assm out of the vehicle; they have to clear the (3) studs extending from the headlamp stud plate. These studs also maintain headlamp alignment so realignment is not necessary after you reinstall the headlamp unit.

**Motor/Actuator – Take note of the linkage to motor relationship for reassembly.

Remove the nut retaining the headlamp assm pivot arm the headlamp motor.

Remove the three (3) bolts mounting the motor to the assm.

Do your motor repair and reverse the process.

Best of Luck! -- Ed
