Worked on headlights today

Today I received 2 new headlight wheels. I had removed the one motor over the weekend and replaced it. It was kinda a plain getting it back together but all was well and it did raise and lower fine.

I was soooo inspired I decided to take apart the driver side one as it worked but was grinding wene going down. I replaced that one and upon testing them both together they did go up and down but now seems to grind going up and down.

The pass side one that did work perfect 2 hours before now maks a noise going up and left side makes noise going down.. ideas???

did you read this already on top of the page? http://www.automotiveforums.com/vbulletin/showthread.php?t=422255

I did read the pinned post and it helped alot but that was before I made my first shot at the head light.

Today I removed the right one and discovered that the seal had came lose. I regreased it and used JB Weld to seal it. I resisted the temptation to re-install today and let the JB Weld to take a strong (oever night ) hold.

MY question is does the gear cover being loose have a direct impact on holding it (the gear) in and producing the motor noise?

In the driverside one (with new gear) it goes up fine but makes the noise whne going down. Its almost as if the motoer keeps spinning whne the light is all the way down and that cuases the problem more than cracked teeth on the gear.

Does anyone have any tips on the placement of the headlights upon the first power on after changing? Could I be lowering it too low and so its spinning down farther than it should?

Any ideas?

Ok redoing both from scratch - I put the one back in and it works perfectly -- lets hope the other goes as well
