About a month ago I had to disconnect my battery for an indoor car show. Once the show was over and we could reconnect our batteries I had to resynchronize all the windows and all that fun stuff. Since then my driver rear window does not work but it worked fine before. I checked all fuses front and rear (spent almost 3 hours taking my system out to get to rear fuse box). What is going on???? Weird stuff..........

 

the fuse is not on the rear but on the inside...#30.

it's on the driver's side, the edge of dashboard facing the door. just pry out that plastic cover.

That is for a different body style than mine. There are no fuses inside the vehicle, they are either under the hood or in the trunk and they are all good

 

My car is the W202 not the W203.

 

sorry. i'm wrong.
can you feel any click or slight movement whenever you try to actuate that window? maybe the window regulator (lifter) is broken?

No I do not feel any movement or hear any relays clicking like I can with the other windows. Weird stuff. Worked fine before disconeccting the battery.

 

then better leave it to somebody who can do the diagnosis to confirm the source of problem. the rear left door control module must have given up.
