Hey Guys. I have a problem with my 1985 coupe 300CD turbo diesel power window. The window on the drivers side will only go up about 3/4 way up and start to slip/skip. I have to pull it up the rest of the way. I tore the door panel off last summer and couldnt really tell because the frame work was in the way...Has anyone else had this problem? Im wondering if a gear is slipping or a tooth broke. Thanks for the help BTW not very mechanically handy.
