If the motor is okay, you needn't replace the entire motor. You only need to get the gear kit. I just learned this and it was very easy. You must remove the motor after removing your interior door panel. Some of the screws that hold the motor in are difficult to get to, however, and you may need to exercise some patience here. Better yet, if you have a hole saw, you can make a hole over where you need to access one or two of the existing screws holding the motor in place. Once you have the motor out, you only need to take the gear cover off, remove the old one (mine were pretty much wasted from heat, age, etc. Next, clean out all the old particles of the old nylon gear and replace it with the new one and put in new grease. (supplied with new gear kit) New gear kits are around 30 bucks and the entire motor is more than double that, so this is a good fix!
