headlight problem

[Carson]

Last night when I came home & turned off the headlights, I heard a 10 second machine gun like noise as the headlight closed. I opened the hood and I could see the manual adjusting screw on the left front headling vibrating. The headlights still go up and down but something is wrong. Also the manual adjuster seems very loose when you grab it and shake. Any idea's? Can it be adjusted (I tried turning the screw) or will it have to be replaced?

thanks dennis

Hi there,
Sounds like you have a stripped driven gear inside one of the headlamp motors.
Unfortunately, there are not any replacement gears out that I know of, only for c4, not c5.
Replacement of the motor will be needed.
Allthebest, c4c5

c4c5 Thanks for the info. I have an gm extended warrantee no problem.


Last week you were going to try and find a parts # for the bushing in the shift linkage. I was concerened that mine might be cracked.

Thanks Dennis

Oh man, forgot all about it.
Thanks for the refresher, and will repost this evening. And people wonder why I use this.

The fix was covered under warranty as well.

Mine is "NOT" under warranty (smile) I have the same problem with my 2000 Navy Blue Metallic corvette. After the lights close about 2 seconds later there is a loud grinding sound for about 6-7 seconds. What do I do ?

If it is the gears there are several aftermarket replacements as well as rebuild kits. Most major web distributors carry them and they offer them in metal as an upgrade. Personally I have not used them (no need at this time) but have seen many ads. Search the web and you will find them, operantly It's a common problem with C5. Good luck, Zig.
