PW9: Check Window Motor Function

Turn the ignition key to the OFF position. Disconnect the power window motor. Apply 12 volts to one lead of the power window motor connector and ground the other lead. Reverse the polarity for 2 seconds. Does the power window motor operate in both directions? If yes for the driver window, see PW14: CHECK POWER WINDOW MOTOR CIRCUIT CONTINUITY  . If yes for the passenger window, go to the next step. If no for either widow, REPLACE the power window motor. See FRONT WINDOW MOTOR  and/or REAR WINDOW MOTOR  under REMOVAL & INSTALLATION.
