Circuit/System Verification
Observe the operation of the power windows while commanding each window UP and DOWN by using their respective window switches, each
window should perform the UP and DOWN function.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the appropriate window motor.
2. Connect a test lamp between control circuit terminal A and control circuit terminal B.
3. Ignition ON, command the window UP and DOWN by using the door switch. The test lamp should turn ON when commanding the UP and
DOWN states.
瀚慖f the test lamp is always OFF during either of the commands, test either control circuit for a short to ground or open/high resistance. If
the circuits test normal, replace the door switch.
瀚慖f the test lamp is always ON, test either control circuit for a short to voltage. If the circuits test normal, replace the door switch
4. If all circuits test normal, test or replace the window motor.
Component Testing
Important: When performing the following tests, make sure that the window motor is not all ready in the position the test is attempting to
produce.
1. Ignition OFF, disconnect the harness connector at the appropriate window motor.
2. Install a 25A fused jumper wire between the control terminal A and 12 volts. Momentarily install a jumper wire between the control terminal
B and ground. The window motor should perform the UP or DOWN function.
瀚慖f the function does not perform as specified, replace the window motor.
3. Reverse the jumper wires; the window motor should perform the DOWN or UP function.
瀚慖f the function does not perform as specified, replace the window motor
