A couple of other thoughts. Check to see if the right rear works. If it doesn't it is possibly a fuse. Also the problem could be the console switch and specially if it is worn to a white circle insread of an image of a window. You might try working with that switch at different temperatures. If none of these work out I'd also go with bound regulator. The motors have a very low failure rate. I'm sure the parts stores sell alot of motors if you ask, but the reason is poor diagnostics and not failed motors. There is a sign at one of the parts suppliers here in the Bay Area. IF THE PART YOU BOUGHT DIDN"T FIX THE PROBLEM, YOU NOW HAVE A SPARE
