it seems on the rear windows, if 1 switch is gummed up, both the front and rear switches will have the same malfunction. i changed the motor on rr window, during testing the motor would not turn if i pressed either switch in the down direction. cleaned out the front switch and now both switches work fine. console switch was full of gunk and filth, used a very fine scotch brite pad to clean the little contacts. i'd try that first.
