About a year ago my headlights were making a grinding sound, so I did what any good Corvette owner would, do and bought brass gears. Did an excellent job installing them, if I do say so myself, and
have had no problems since.
However, this week when I turn them off they both lowered as expected; but mysteriously the left on starts rising again to about half way. and stays there untill I manually crank it down.
Is there anything anyone can tell me before I try to pull the gears apart again?
I'm begining to think they have the right idea with C6 headlights!

 

There was a TSB published a while ago. The original came with a diagram:

Number: 00-08-42-002
Subject: Left Headlamp Door Does Not Stay Closed (Shim Headlamp Door Motor/Actuator and Replace Insulators)
Model Year: 2000 Chevrolet Corvette
Condition
Some customers may comment that the left front headlamp door does not remain closed after the headlamps are turned off. Others may comment that the left headlamp door closes when the headlamps are turned off, but then reopens. In either case, the right headlamp door operates properly.

Correction
Important
The following information applies to the left front headlamp door motor/actuator only. It does not apply to and should not be performed on the right front headlamp door motor/actuator.
Install one washer (2) between the left headlamp door motor/actuator (1) and the mounting bracket (3) at each of the three attaching bolt locations. Also replace the insulator (4) on each of the two mounting bracket travel stop tabs (5) as shown. For information on headlamp motor/actuator removal, see the Headlamp Motor/Actuator Replacement procedure in the Lighting sub-section of Body & Accessories in the appropriate Service Manual.

I can send a copy if you PM me with your E Mail. Hope that helps.

 

Thanks for the info.
