Power windows......HELP!!
 

I have been searching the threads, but am not finding what I need to fix my windows. I have an 85 300d. I want to repair the windows, but need to have an idea of where to start and what to look for.

Drivers side front: Push the button down. Window goes down. Push the button up, nothing happens. When you pull the glass up, you can push the "up button" and the window regulator will hold the glass back up.

Drivers rear: nothing, no noise, nothing!

Passenger front: Works perfectly.

Passenger rear: worked at first but when you would push the button to go back up and the window reached it's "most up position" you would hear a bump...bump....bump....bump, coming from the window. Now it does not work at all and all you hear is bump...bump....bump!!

I really want to repair all of them, but priority is the front driver!!

Thanks!! JC

Search for posts with "Window Regulator"

DS front- Missing teeth on the bottom of the regulator
DS rear- either bad/dirty switch, bad motor or short in the wiring. Does it work with either switch? swap switches with a known good one before going further.
PS rear missing teeth on the top of the regulator

Good info here....Do the ones that you say have worn out/missing teeth, will I need to replace the whole regulator assembly or just the $5 plastic part?

I have not checked to see if the rear dr window will work by swapping switches.... I will do that and report back!!

Thanks! JC

The regulator and the electric motor may be separately replaceable. The gears, AFAIK, are not.
