Passenger Window Inoperative From Both Switches

Possible Causes:

    NOTE: Ensure there is communication with the Passenger and Driver Door Modules before proceeding.
  1. Connect the DRBIII(R) and select: BODY, DOOR MODULES and ACTUATORS. Using the DRBIII(R), actuate the PASS F WIN UP RLY and then the PASS F WIN DN RLY. Did the window operate up and down? If yes, replace the Passenger Door Module (switch input open). Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  2. Disconnect the Passenger Door Module C1 connector. Keep the window area clear as the window should move up and down in this test. Connect a jumper wire from the Passenger Window Driver Down terminal to the ground terminal. Connect a jumper wire from the Passenger Window Driver Up terminal and momentarily connect it to the Fused B (+) terminal. Reverse the jumper wires to run the motor in the opposite direction. Did the window motor operate up and down? If yes, replace the Passenger Door Module (output open). Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  3. Disconnect the Passenger Door Module C1 connector. Turn ignition off. Measure and record the total resistance of the motor circuit between the Passenger Window Driver Up circuit and the Passenger Window Driver Down circuit in the PDM C1 connector (should be under 5 ohms). Measure and record the resistance of the Passenger Window Driver Down circuit to ground in the PDM C1 connector (should be infinite). Turn ignition on. Measure and record the voltage of the Passenger Window Driver Down circuit to ground in the PDM C1 connector (should be zero). What were the readings?
    • Total resistance more than 5 ohms, go to next step.
    • Resistance to ground is less than 1000 ohms, go to step  7 .
    • Voltage more than 0.02 volts, go to step  10 .
    • None of the above, check and repair any reasons for the window regulator to bind. If the mechanism is OK, replace the power window motor. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  4. Disconnect the Passenger Door Module C1 connector. Disconnect the Passenger Power Window Motor connector. Measure the resistance of the Passenger Window Driver Down circuit between the PDM connector and the window motor connector. Is the resistance less than 5 ohms? If yes, go to next step. If no, repair the Passenger Window Driver Down wire for an open. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  5. Disconnect the Passenger Door Module C1 connector. Disconnect the Passenger Power Window Motor connector. Measure the resistance of the Passenger Window Driver Up circuit between the PDM connector and the window motor connector. Is the resistance less than 5 ohms? If yes, go to next step. If no, repair the Passenger Window Driver Up wire for an open. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  6. If there are no possible causes remaining, replace the power window motor. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  7. Disconnect the Passenger Door Module C1 connector. Disconnect the Passenger Power Window Motor connector. Measure the resistance of the Passenger Window Driver Down circuit to ground. Is the resistance less than 1000 ohms? If yes, repair the Passenger Window Driver Down wire for a short to ground. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  8. Disconnect the Passenger Door Module C1 connector. Disconnect the Passenger Power Window Motor connector. Measure the resistance of the Passenger Window Driver Up circuit to ground. Is the resistance less than 1000 ohms? If yes, repair the Passenger Window Driver Up wire for a short to ground. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  9. If there are no possible causes remaining, replace the Power Window Motor (internal short). Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
  10. Disconnect the Passenger Door Module C1 connector. Disconnect the Passenger Power Window Motor connector. Measure the voltage of the Passenger Window Driver Down circuit to ground. Is there any voltage on the Passenger Window Driver Down wire? If yes, repair the Passenger Window Driver Down wire for a short to voltage. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
  11. Disconnect the Passenger Door Module C1 connector. Disconnect the Passenger Power Window Motor connector. Measure the voltage of the Passenger Window Driver Up circuit to ground. Is there any voltage on the Passenger Window Driver Up wire? If yes, repair the Passenger Window Driver Up wire for a short to voltage. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, test is complete.
