DESCRIPTION & OPERATION
| CAUTION | When 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. |
The power window operates when the ignition is "ON". To open the window, press the switch and hold it down. The main switch (driver's switches) will open or close all the windows. (Scheme 1)
Scheme 1
Locking Passenger's Window
When the lock button is pushed in, only the driver side window can be opened or closed. Push it again to cancel. (Scheme 1) The passenger's switch will open or close only the passenger's window. To open or close the window, hold the switch down. (Scheme 2)
Scheme 2
ONE TOUCH (AUTO) OPERATION
To fully open the driver side window, completely press down the switch and release it; it need not be held. The window will automatically open all the way. To stop the window, just press the switch on the opposite side.
A light press in the switch will cause the window to open while the switch is pressed. (Scheme 3)
Power window system is designed to fully close the driver's window automatically by one touch (auto) operation of driver's door window switch. Stopping the window at the fully open or closed position is done by power window amp. operation.
Scheme 3
PRELIMINARY INSPECTION
Verify customer complaint by operating suspected system. Visually inspect for obvious signs of mechanical and electrical damage. Inspect for blown fuses and damaged relays. Inspect for loose or corroded connections, damaged wiring harnesses and/or switches. Check for a broken or partially broken wire inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. Ensure any aftermarket electronic equipment is properly installed. If fault is found, repair as necessary.
