Headlight woes

[foxtrot]

one of my headlamp motors is moving slow.Does anyone have any experience with the rebuild of these units? Where can I get the replacement gears for the rebuild? Any help would be great. thx Ken.

Manny can get you the parts you need from Corvette Central or you can order directly yourself.
It's a common issue with C4's.

Delrin bushings are the usual culprit (there are three little capsules).....about $10. Basic tools, 1 hour per side, re & re, basic hand tools. Second one actually goes faster because ofexperience. 2/10 difficulty scale.

Thanks Range, going to replace gears and bushings.I found a good video on line that walks you through the process.Cheers Ken.

As Range has pointed out, usually the bushings are the culprits. 3 plastic pellets that disintegrate with age. I did both of mine and in both cases the gear was ok, only the bushings needed replacing. $10 vs $80 or so for the brass gear...

My headlamps come up when starting the car in about a minute they shut, checked bushing and they seemed fine. Problem is at night if I turn on headlights with engine off they work, but if engine is running lights won't come on? Also right side lamp doesn't seem to come up all the way ? Could this be a motor issue and perhaps a wiring issue as lights don't turn on if engine is running?
