Power Windows Ford Escort V

DESCRIPTION & OPERATION

The power window system consists of one main switch, individual passenger switches and a power window motor for each window. The main switch is located on the driver's door armrest and the front passenger switch is on the passenger door armrest. When the main switch/lock is actuated, the windows may only be operated by the driver's door switches.

The power windows are regulated by two encased cables connected to an electric motor that drives the regulator and slider bracket. When the power window switch is operated, the cables move the slider bracket up or down to the desired position.

PW3: POWER WINDOW OPERATION CHECK

Turn the ignition key to the ON position. Operate all the power windows with switches one at a time. Check to see that the windows are operating properly with no binding or abnormal noises. If the windows operate properly the system is OK. If no, go to the next step.

PW4: CHECK FOR SHORTS TO GROUND

1. Turn the ignition key to the OFF position. Disconnect the power window main switch. Measure the resistance between the main switch connector, include all terminals except (Black), (Black/White) and ground. See «WIRING DIAGRAMS»(/ford/escort/v-1990-1992/remont/windows/#power-windows) .
2. Check to see if the resistance is greater than 10,000 ohm's. If yes, replace the power window main switch. If no, service the circuit in question for a short to ground.

PW5: CHECK FOR POWER SHORTS TO GROUND

Turn the ignition key to the OFF position. Disconnect the interior fuse panel connector located behind the left hand side of I/P on left of the steering column. Disconnect the power main switch. Measure the resistance between the (Black/White) wire at the interior fuse panel connector and ground. See WIRING DIAGRAMS . Check the resistance, is it greater than 10,000 ohms? If yes, replace the power window main switch. If no, service the (Black/White) wire between the power window main switch and the interior fuse panel for short to ground.

PW6: CHECK POWER SUPPLY

Disconnect the power window main switch. Turn the ignition key to the ON possition. Measure the voltage on the (Black/White) wire at the power window main switch connector. See WIRING DIAGRAMS . Check the voltage, is it greater than 10 volts? If yes, go to the next step. If no, service the (Black/White) wire between the power window main switch and the interior fuse panel for open.

PW7: CHECK GROUND CONTINUITY

Turn the ignition key to the OFF position. Disconnect the power window main switch. Measure the resistance between the (Black) wire at the power window main switch connector and ground. See WIRING DIAGRAMS . Is the resistance less than 5 ohms? If yes, replace the power window main switch. If no, service the (Black) wire between the power window main switch and ground for open.

PW8: CHECK POWER WINDOW SIGNAL

Turn the ignition key to the OFF position. Disconnect the power window main switch. Apply 12 volts to the wires marked (+) and ground the wires marked (-) shown below for 2 seconds, see WIRE VOLTAGE APPLICATION . Reverse the polarity for 2 seconds. Does the power window operate in both directions? If yes, replace the power window main switch. If no, go to the next step.

WIRE VOLTAGE APPLICATION

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.

PW10: CHECK PASSENGER SWITCH CIRCUIT CONTINUITY

Turn the ignition key to the OFF position. Disconnect the power window main switch. Disconnect the passenger switch for the window that is not working. Measure the resistance between the main switch connector and passenger switch connector of the window that is not working, see POWER WINDOW SWITCH CONNECTOR . Is the resistance less than 5 ohms?
