I took the easy route and replaced my headlight with a plastic gear twice and even though they strip, they shouldn't strip after only three tries(meaning headlights on and off three times before it makes that grinding noise) so I am guessing my motor is bad. I can buy one off eBay for around $100 bucks but I rather ask you guys on here first. I have looked at my local junk yard and they have one bird that has been wrecked in the drivers side so no luck there. Anywho, hope to hear from someone as I'm tired of the grinding noise. Thanks!
