        Fit is as advertised.

        Perfect fit. Bolts right up. Easy. Electrical connections are identical to OEM. Took 30 minutes, tops. Quieter than the other three! Very satisfied.

        Great power window motor!

        I recently purchased a replacement rear power window motor for my 85 LX. I was pleased with the ease of installation of the motor. I am very pleased with how well it works and how quiet it is. I know where To go when the other one needs replacement!

        Works good!

        Had a clicking noise and window would not come all the way up. Ordered motor and had mechanic scheduled to install. He called to tell me other window was not working so ordered the other window motor for installation. Moral is if one quater motor needs replacement the other propbably needs replacement. Might as well since you are pulling bottom rear seat and panel.

        Power Quater Window Motor

        This product worked very well, I haven't been able to roll my back windows down until I installed the window motors. I love the quality of this project and what it does.

        Power quarter window repair review

        I purchased a motor for my 91 mustang convertable, and it was everything I hoped it would be. The price was great, the part fit to specs and my window worked perfectly after install. Took about an hour, only becauseI didn't know what I was doing. Will definitely order parts from here again!

      2 Top Rated Questions

      Does the new motor come with gears and pins? Can I just get the gears. The motors work fine.

      • The OPR Power Quarter Window Motor will include the motor and drive gear only.

      Are these high torque motors? My GT convertible windows will not operate on the standard ones very well.

      • The Power Quarter Window Motor - Driver Side - Convertible (84-93 All) is manufactured to OEM specs, so this is designed to function just like the standard motors that came from the factory.
