DESCRIPTION & OPERATION

WARNINGVehicles are equipped with air bag supplemental restraint system. Before attempting ANY repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in appropriate AIR BAG RESTRAINT SYSTEMS article.

The power windows system is powered from the Ignition Switch through the POWER WIND fuse (30 amp) of the Interior Fuse Panel and is hot when the Ignition Switch is in the START or RUN positions. When either of the two Window Switches are activated, current flows from the Ignition Switch through the Window Switch(es) to one lead of the Power Window Motor for UP or the other lead for DOWN.

The current causes the Power Window Motor to rotate in a clockwise or counterclockwise direction to raise or lower the window. Both motor leads are grounded through the Power Window Main Switch when all the Window Switches are OFF. The Driver's side has a Power Window Main Switch which can raise or lower any of the windows. The Power Window Main Switch has a lock switch which cuts the power to the right hand Power Window Switch. This allows only the driver to operate the windows.

LUBRICATION

The front door windows are operated by two encased cables. The cables are attached from the motor to the regulator's slider bracket. The cables are secured by nylon fasteners inside the door. Lubrication of the cables is not necessary. The door window mechanism should be well-lubricated to provide ease of operation.

The mechanism should be lubricated whenever the glass channel or window regulator is removed or when excessive effort is required to operate the windows. To lubricate the door window mechanism, apply an even coating of Multi-Purpose Grease (DOAZ-19584-A), or equivalent, to the window regulator guides and entire length of channel. (Scheme 4)

TESTING PROCEDURE

Do NOT start POWER WINDOW PINPOINT TEST before going to TROUBLE SHOOTING section. Find symptom that matches problem with vehicle. Symptom trouble shooting will direct you to appropriate pinpoint test.

A1: Check Fuse

Locate the interior fuse panel. Turn the ignition switch to OFF. Remove and inspect 30 amp POWER WINDOW fuse. Is fuse okay? If yes, then go to A5: Check Power Supply To Power Window Main Switch . If not, then go to next step.

A2: Check System

Replace 30 amp POWER WINDOW fuse. Turn the ignition switch to ON. Reinspect the 30 amp POWER WINDOW fuse. Does the fuse fail again? If yes, then go to A3: Check Power Window Operation . If no, go to A4: Check For Short To Ground .

A3: Check Power Window Operation

Turn the ignition switch to ON. Operate all power windows with switches one at a time. Are power windows operating properly? If yes, then system is functioning properly at this time. If not, then go to A5: Check Power Supply To Power Window Main Switch .

A4: Check For Short To Ground

Turn ignition switch to OFF. Locate and disconnect interior fuse panel connector. Disconnect power window main switch. Measure resistance between Black/Red wire at interior fuse panel connector and ground. See WIRING DIAGRAMS . Is resistance greater then 10,000 ohms? If yes, then replace power window main switch. See POWER WINDOW SWITCH under REMOVAL & INSTALLATION. If not, then repair Black/Red wire. Retest system for normal operation.

A5: Check Power Supply To Power Window Main Switch

Disconnect power window main switch. Turn ignition switch to ON. Measure voltage on Black/Red wire at power window main switch connector. See WIRING DIAGRAMS . See WIRING DIAGRAMS . Is the voltage 10 volts or greater? If yes, then go to A6: Check Power Window Main Switch Ground . If not, then repair Black/Red wire between power window main switch and interior fuse panel.

A6: Check Power Window Main Switch Ground

Turn ignition switch to OFF. Disconnect power window main switch. Measure resistance between Black wire at power window main switch connector and ground. See WIRING DIAGRAMS . Is resistance less than 5 ohms? If yes, then go to A7: Check Power Window Main Switch . If not, then repair Black wire between power window main switch and ground.

A7: Check Power Window Main Switch

Turn ignition on, with engine off. Locate power window main switch. Check voltages between Black wire and and other terminals. See WIRING DIAGRAMS. (Scheme 6) If all voltages are not correct, replace power window main switch. If all voltages ARE correct, and driver's windows does not work, go to A11: Check Power Window Motor Circuit Continuity. If all voltages ARE correct and passenger's window does not work, go to A8: Check Wire To Passenger Switch.

Scheme 8: A7: Check Power Window Main Switch

A8: Check Wire To Passenger Switch

Disconnect passenger power window switch. Turn ignition switch to ON. Push power switch on power window main switch to ON position. Measure voltage on Black/Blue wire at passenger power window switch connector. See WIRING DIAGRAMS . Is the voltage 10 volts or greater? If yes, then go to A9: Check Passenger Switch Circuit Continuity . If not, then repair Black/Blue wire between power window main switch and passenger power window switch.

A9: Check Passenger Switch Circuit Continuity

Turn ignition switch to OFF. Disconnect power window main switch. Disconnect power window passenger switch. Measure resistance of the Green/Black and Red/Black wires between the main switch connector and the passenger switch connector. See WIRING DIAGRAMS . Is the resistance less than 5 ohms? If yes then go to A10: Check Power Window Passenger Switch . If not, then repair Green/Black and Red/Black wires between main switch and passenger switch.

A10: Check Power Window Passenger Switch

Turn on ignition, with engine off. Push power switch on main switch to ON position. Check voltages between specified wiring and ground while moving the switch.

  1. UP: Green wire should be less than 1 volt. Red wire should be more than 10 volts.
  2. DOWN: Green wire should be more than 10 volts. Red wire should be less than 1 volt.

If power window switch is okay, go to

. Replace if defective, then retest system for normal operation.

A11: Check Power Window Motor Circuit Continuity

Turn ignition switch to OFF. Disconnect power window main switch, passenger switch and window motors. Measure resistance of the Red and Green wires between the power window switches and power window motors. See WIRING DIAGRAMS . If resistance is less than 5 ohms, go to A12: Check Power Window Motor Function . If resistance is not less than 5 ohms, repair wiring between power window switches and power window motors. Retest system for normal operation.

A12: Check Power Window Motor Function

Test power window motor. See MOTOR under COMPONENT TESTS. Replace if necessary. See MOTOR under REMOVAL & INSTALLATION. If motor is okay, retest system for normal operation.

MOTOR

Disconnect power window motor. Apply 12 volts to one lead of the power window motor connector and ground the other lead for at least two seconds. Reverse polarity of the leads for at least two seconds. The motor should operate in both directions. Replace motor if necessary. See MOTOR under REMOVAL & INSTALLATION.

REMOVAL & INSTALLATION

CAUTIONWhen battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
