Default C5 Headlight Grinding Sound

Just got a 2001 C5 Coupe. When I turn the headlights on, they pop up without issue. When I turn them off, they drop down and then there’s a loud grinding sound for 3-4 seconds from the passenger side light area. Do I need a new headlight motor, or is there possibly a simpler repair? Thanks!

Yep, it’s the gears. Plenty of options out there for parts but I’d recommend finding the brass option.

Save yourself time and aggravation. Order 2 kits from Rodney Dickman - both motors have the same wear.

replace the tired 20 year old motor assembly with a fresh pair of new motors...the new pair isn't all that expensive and should last another 2 decades

Thanks!

Looks like $160 for the pair of motor assemblies from Amazon, and $101 for the pair of gear kits from Rodney Dickman (including shipping): http://rodneydickman.com/product_inf...products_id=92

If I had more time on my hands I’d probably go for the gear replacement, but I’m thinking I’ll replace the entire motor assembly to save time.

Just be sure those are for Corvette. The F bodies have a different length shaft and if that is the case you will be taking the motors apart if you wish to keep them. I looked at the Amazon listing and they list for a corvette but picture a F body. I looked up the other wiper motors from that company and they have the same exact F body pictures but list for firebird.

Amazon Amazon

Maybe JDM can verify they are correct.

The bulb connections in the Amazon link appear to be from a C5.




The firebird bulb connections look quite different.






I went through the process of putting firebird motors in my c5 and it can be done you just have to swap some things around

I just replaced motor from rock auto. Didn't want to crack the motor open and glue it back together. I think early c5 are bolted together.

Does the replacement motor bring same nylon gear? If it does it will wear out again, I went cheap purchased a set of nylon gears each laste about a year. Now I purchased the brass gear.

On my 98, I replaced the gear with the brass replacement about 2 years ago on the driver side.
The motor was not glued together - it was serviceable, and not a tough job.
I still have the other metal gear in a box in the garage.. the passenger side has not failed yet!
