1996 monte carlo windows will not go down or up from drivers side master switch and pass side will only go down. I know both switches are good, I pulled them and put in 1995 monte and they work fine in all postions. Pulled the cover off pass door and tested motor directly works fine up and down. Checked the continuity of each wire between pass door and drive door all fine. Its seems like I have a ground problem.
does anyone know where the ground is being pulled from for the motors?
is it from the door itself or from the wiring?
Or any ideas for more advanced testing?
Do you
have the same problem?

TESTING WINDOWS DO NOT OPERATE 1. Turn ignition switch to RUN position. Using a test light, backprobe between ground and Brown wire terminal at master switch connector. If test light is on, go to next step. If test light is off, check for poor connection at master switch. If connection is okay, repair open in Brown wire between power window 20-amp breaker and master switch. 2. Backprobe between Brown wire and Black wire terminals (ground) of master switch connector. If test light is on, check for poor connection at master switch. If connection is okay, replace master switch. If test light is off, check for poor connection at ground connection. If connection is okay, repair open in Black wire between master switch and ground connection. LEFT FRONT WINDOW DOES NOT OPERATE 1. Turn ignition switch to RUN position. Using a test light, backprobe between Dark Blue wire and Brown wire terminals at master switch connector. While observing test light, press left window switch at master switch to up and down positions. If test light is on, go to next step. If test light is off, check for poor connection at master switch. If connection is okay, replace master switch. 2. Backprobe between Dark Blue wire and Brown wire terminals at left window motor connector. While observing test light, press left window switch at master switch to up and down positions. If test light is on, check for poor connection at left window motor. If connection is okay, replace left window motor. If test light is off, repair open in Dark Blue wire or Brown wire between left window switch and motor. RIGHT FRONT, LEFT REAR OR RIGHT REAR WINDOW IS INOPERATIVE AT INDIVIDUAL SWITCH, OPERATES AT MASTER SWITCH 1. Turn ignition switch to RUN position. Press window lock-out switch to off position (if equipped). Using a test light, backprobe between ground and Brown wire terminal (2-door) or between ground and Light Blue wire terminal (4-door) at inoperative window switch connector. If test light is on, go to next step. If test light is off, repair open in Light Blue wire or Brown wire between master switch and inoperative window switch. If wires are okay, replace master switch. 2. Backprobe between Dark Blue wire and Brown wire terminals at inoperative window switch connector. While observing test light, press inoperative window switch to up and down position. If test light is on, repair open in Dark Blue wire or Brown wire between inoperative window switch and motor. If wires are okay, replace motor. If test light is off, check for poor connection at inoperative window switch. If connection is okay, replace inoperative window switch. NOTE: Left front window switch is referred to as master switch. For circuit identification, see WIRING DIAGRAMS . ONE WINDOW (EXCEPT LEFT FRONT) INOPERATIVE FROM MASTER & INDIVIDUAL SWITCH, ALL OTHERS OPERATE 1. Turn ignition switch to RUN position. Using a test light, backprobe between Dark Blue wire and Brown wire terminals at inoperative window motor connector. While observing test light, press inoperative window switch to up and down positions. If test light is off, go to next step. If test light is on, check for poor connection at inoperative window motor. If connection is okay, replace inoperative window motor. 2. Disconnect inoperative window switch connector. Connect test light to inoperative window switch between Light Blue wire and Tan wire terminals at right window switch connector, Light Green wire and Purple wire terminals at right rear window switch connector and Dark Green wire and Purple wire terminals at left rear window switch connector. 3. While observing test light, press inoperative window switch at master switch to up and down position. If test light is on at all specified wire terminals, go to next step. If test light is off at any wire terminal, check for poor connection at inoperative window switch. If connection is okay, repair open in appropriate wire(s) to inoperative window switch. If wire(s) are okay, replace master switch. 4. Backprobe between Dark Blue wire and Brown wire terminals at inoperative window switch connector. While observing test light, press inoperative window switch at master switch to up and down position. If test light is on, check for poor connection at inoperative window motor, or repair open in Dark Blue wire or Brown wire between inoperative window switch and motor. If wire is okay, replace motor.
