There is no headlight motor. The entire headlight raising and lowering function is controlled by the cars vaccume system.If your headlights don't operate correctly,I suggest that you either check the vac. hoses or the vac diaphragm's located under the hood in front of the radiator.
I have a 1988 corvette I need to change the headlight motor but cant get the motor free from the body This answer is a question.
MANUAL HEADLIGHT MOTOR KNOB ON MOTOR. IT SHOULD BE IN YOUR MANUAL ALSO.
Maybe the headlight motor is wired backwards.

If you go to corvettemagazine.com and click on there tech link they had an article that tells you step by step with pics how to repair the headlight motors
If your relays are working properly, you might have a stripped gear in the motor. You can replace the gear or the motor depending on your resources. If the headlight is loose, the gear more than likely has teeth missing.
bad headlight switch
the same thing happened to me. i bought a rebuilt headlight motor
If you mean the headlight motors, go to corvettemagazine.com and click on the technical link. they have the procedure with photos and you can get the bushings (use Delrin, not nylon) on eBay for less than $10 to do both. it takes about 1 hour per headlight opposed to paying $300 per headlight to have it done.
Failed limit switch, or bad wiring. The motor will keep running until the headlight finds "home" ... ergo a failed limit switch as mentioned above. The sensor at the "home" position (headlight off) has to be tripped by the headlight assembly before the motor will shut down. The motor has no idea where the headlight physically is ... it keeps running until the switch is engaged.
hmm seems to me that the the light assembly mabye bent or that the sighn that the ,motor is on its way out Is there a stop switch?

Please see the same question on the 91 Capri. The procedure is the same.
The plastic gears in the headlight motors are weak. I had the same problem with my 1984 Corvette. You can get a new motor, but it's much cheaper to get new gears. Check out the C4 section at CorvetteForum.com for a how-to on replacing it.
Take a jump over to Smokinvette.com and click on the C4 technical section and you will see the thread with detailed instructions on this. Good luck!
I don't own a C4, however there are detailed directions on how to do this at Smokinvette.com and with pics too! So it is really laid out to make it an easy job. Are you changing the cheap plastic gears? A ton of C4 owners have and put in the brass gears. Good luck.
YES THE MOTOR WILL REV LESS BUT U HAVE TO CHANGE THE SHIFTER
The 90 Corvette had a 350 c.i. engine
The headlight motor needs to be removed, and replaced. To change the motor on the passenger side of the car you must jack-up the car, then support it with a jack. Remove the front wheel, and remove the splash guard in the wheel well to access the headlight motor. The instructions for this procedure can be found in a Haynes Repair Manual that covers the Ford Probe, Mazda 626, and Mazda MX6.
