I have a 93 GS 300. Two weeks ago left rear window stopped working, then last week my right rear stopped working, and today the left front stopped working. The LR and LF don't move at all and I don't hear any motor noise. The RR seems to have a different problem: it will go down but not up. I can pull it up by hand to about 2" from the top. Any ideas short of replacing the motors? Any connection that are easy to check? At the very least, is there an easy way to fully close the RR window? I'd be happy to leave the rear windows closed all the time, but I'd really like to be able to use the driver's window for paying tolls and just getting some air.
