 Mazda B3000
My heartfelt thanks for taking the time to post the instructions and the photos. Because you took the time to post, I was able to successfully replace the power window motor on my 2002 Mazda B3000.
May I add a couple of comments?
As mentioned, the motor was attached by four screws, three of them directly into the motor. (It was one of these three that required drilling the hole.) The fourth screw went through the door and into a bracket that was in turn attached to the motor. (This is the screw that is located nearest the bottom and the rear of the door.)
I purchased a new motor at AutoZone for about $70, but found that while it looked very much like the old motor, it wasn't exact. It did not come with the bracket attached and it wasn't designed to accept the bracket, which I could have removed from the old motor. Still, because the remaining three holes lined up, I gave it a try.
Didn't work, at least for me. The window went up and stopped properly, but when it reached the bottom of its excursion, the motor moved around inside the door and the motor's gear teeth became disengaged from the regulator teeth. A terrible chattering ensued and I could see that the regulator's teeth were being damaged.
My point is, it appears that the fourth point of attachment, provided by the bracket mounted on the motor is important for stability of the motor and without it the motor may move, disengaging the gear from the regulator.
I returned the motor to AutoZone and went up the street to O'Reilly's. They sold me what I needed for $45 (after swapping out the old motor). The remanufactured motor looked identical to the old motor and included the bracket I mentioned.
Took 5 minutes to install, worked beautifully.
(I applied a little grease to the gear and to the regulator teeth. Seemed like a good idea.)
Thanks again. |
