left rear window died ?
 

Two months ago i cleaned and lubricated all window switches etc. because the right rear window did not work, then after i cleaned and lubed all switches that window started working great. Now the left rear window does not move at all ,everything else works. all fuses okay ,I took door panel off and checked power to window switch on door going to window motor okay next I push window switch and I could hear a light clicking sound with each time I push the switch down so lastly I would guess that the window motor is broke I checked everything up to this point. It does not look easy to get the motor out of the inner door panel has any one done this ? thanks Hans.

First check that the plastic slide in the bottom channel is not broken. I had a similar situation with a rear window. I popped the end on the regulator arm back into the plastic block & channel. Works fine as long as I dont lower the window all the way. Will do the permanent fix someday soon. Do a search for the how to.
