My driver side front power window stopped going all the way down, it goes about 1/4 way down, stops and starts making clicking noise. It will go back up but when it gets to top, starts clicking noise.
Do you
have the same problem?

Sounds like something's slipping in the motor and/or regulator. The motor turns a pinion gear, which turns a wheel that moves a kind of strap that runs in a track and is attached at the other end to the bottom of the window.

Thanks for the response. I do have the panal off and can see the strap you are referring to. It appears to be worn but still in one piece. Any idea how difficult to replace the motor?

Try running the window with the panel off and maybe you can see the problem. The motor and regulator are attached with rivets to the inside of the door. If you have to replace one or both, you have to destroy the rivet heads with a drill and cold chisel and pull the motor/regulator unit out through the opening. I think there are four rivets -- top and bottom of the track and two for the regulator.

If you have to separate the motor and regulator, there are three smaller rivets holding them together. Replace all rivets with bolts to reinstall. Before removing the regulator and motor, you'll also have to tape the window glass in the frame and remove the two bolts holding it to the regulator. Replacement motors aren't cheap, about $45, but are easily available. I guess if you had to replace a regulator you might have to get it from the junkyard.

Allright, sounds like a good weekend project. Ive allready located the motor, and will check out some of the local junk yards for the regulator. The motor sounds good and stong so I think the problem lies in the regulator( perhaps some broken teeth on gear). But while I have the Panal off I might as well replace everything. Thanks again for your time.
