first issue regarding the window only working one way from the master switch on your door means the switch on your door is bad. if the rear window aint working at all with the switch on your door or the switch on the rear right door itself then its definetly the motor is bad on that door.
also does the passanger window work at all from its own switch ? if yes then its just the switch on your door thats bad but if it too dont work then its possible that both switches are bad.... easy to replace. and cheap.. maybe no more then $6 at any of your local junk yards
