The driver and passenger door lock and side window switches are integrated control module switch assemblies. When a power window switch is activated in the up or down positions the driver door switch (DDS) supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the DDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist and during window motor operation the DDS continues to monitor the motor current to verify proper window motor operation.

⇒ | If the driver window malfunctions, refer to Driver Window Malfunction. |
⇒ | If the front passenger window malfunctions, refer to Passenger Window Malfunction. |
⇒ | If either rear passenger power window malfunctions, refer to Rear Passenger Window Malfunction. |
⇒ | If the value does not change, replace the DDS. |
⇒ | If the value does not change, replace the DDS. |
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. |
⇒ | If the value does not change, replace the DDS. |
⇒ | If 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 DDS. |
⇒ | If the test lamp is always ON, test either control circuit for a short to voltage. If the circuits test normal, replace the DDS |
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. |
⇒ | If the value does not change, replace the PDS. |
⇒ | If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the PDS. |
⇒ | If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the PDS. |
⇒ | If the test lamp is always OFF during either of the commands, test either control circuit for a short to ground. If the circuits test normal, replace the PDS. |
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. |
⇒ | If less than the specified range, test the control circuit for a short to ground or open/high resistance. If the circuit tests normal, replace the BCM. |
⇒ | If less than the specified range, test the signal circuit for a short to ground or open/high resistance. If the circuit tests normal, replace the BCM. |
⇒ | If less than the specified range, test the signal circuit for a short to ground or open/high resistance. If the circuit tests normal, replace the BCM. |
⇒ | If 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 rear window switch. |
⇒ | If the test lamp is always ON, test either control circuit for a short to voltage. If the circuits test normal, replace the rear window switch. |
⇒ | If it does not perform as specified, replace the window motor. |
