Is one of the motors newer or did you only replace the gear? I replaced my entire driver side motor a couple months ago and it's a little "quicker" than the OEM motor. It's not a problem and I wouldn't lose a wink of sleep over it. Unless it's creating an issue or REALLY off, I wouldn't worry about it.

No I just replaced the gears reinstalled the assembly. The drivers side malfunctions the same every time. The passengers side works one time and won't even open the next. So it really has me confused.

So all you did was replace BOTH gears in BOTH OEM motors? Sounds like that's what you're saying. It does sound like you have the arms installed wrong. I'd recommend detaching both arms, manually lifting each headlight all the way open, then reattach the arms on both. While holding the headlight up manually, you'll probably need to spin the motor manually until the arms line up to fit correctly on the rod. Basically you'll want everything re-installed with both headlights open. If everything worked fine before and that's all you replaced, I don't see why that wouldn't fix it.

So which motor did you repair? One or both? We need more information. Also, like I said, did you make sure to put the arm back on the motor exactly like it came off? This is a common mistake when the headlights are out of sinc. Also, you may need to just loosen the motor that is sticking slightly to release the tension on the gear. Less than a quarter turn.
