Right Front Power Window Inoperative

Right Front Power Window Inoperative:

POSSIBLE CAUSES
- Right front power window switch
- Right power window switch sense circuit
- Right front power window motor
- Right front power window motor circuit
- Body control module internal failure

Diagnostic Test




1. TEST THE RIGHT FRONT POWER WINDOW MOTOR

Turn the ignition off.
Disconnect the Body Control Module (BCM) harness connector.

NOTE: Check connectors - Clean/repair as necessary. Connect a fused jumper wire from cavity 10 of the BCM harness connector to B(+).

Connect a second fused jumper wire to cavity 11 of the BCM harness
connector and momentarily connect the jumper to ground. Note window movement; if no right front window movement is noted, reverse the jumper wires at the B(+) and ground connections.

Q: Did the right front window move upward or downward?

YES: Go to 3
NO: Go to 2




2. MEASURE RIGHT FRONT POWER WINDOW MOTOR CIRCUIT RESISTANCE

With the ignition off.
Disconnect the Right Front Power Window Motor harness connector.

NOTE: Check connectors - Clean/repair as necessary. Connect a jumper wire between cavity 1 and cavity 2 of the Right Front Power Window Motor harness connector. Measure the resistance between cavity 10 and cavity 11 of the BCM harness connector.

Q: Is the resistance below 5.0 ohms?

YES: Replace the Right Front Power Window Motor. Perform BODY VERIFICATION TEST. Body Verification Test
NO: Repair the Right Front Power Window Motor circuit for an open. Perform BODY VERIFICATION TEST. Body Verification Test




3. MEASURE THE VOLTAGE OF THE RIGHT POWER WINDOW SWITCH SENSE CIRCUIT

With the ignition off. Disconnect the Right Front Power Window Switch harness connector.

NOTE: Check connector - Clean/repair as necessary.

Turn the ignition on.
Measure the voltage of the Right Power Window Switch Sense circuit at the Right Front Power Window Switch harness connector.

Q: Is the voltage above 10 volts?

YES: Replace the Right Front Power Window Switch. Perform BODY VERIFICATION TEST. Body Verification Test
NO: Go to 4




4. MEASURE RIGHT POWER WINDOW SWITCH SENSE CIRCUIT RESISTANCE

Turn the ignition off.
Measure the resistance of the Right Power Window Switch Sense circuit from the Right Front Power Window Switch harness connector to the BCM harness connector.

Q: Is the resistance below 5.0 ohms?

YES: Replace the Body Control Module. Perform BODY VERIFICATION TEST. Body Verification Test
NO: Repair the Right Power Window Switch Sense circuit for an open. Perform BODY VERIFICATION TEST. Body Verification Test
