Diagnostic Test

  1. INTERMITTENT CONDITION 
    1. Turn the ignition on.
    2. With the scan tool, record and erase the DTCs.
    3. Try to operate the driver and then the passenger power windows several times.
    4. With the scan tool, read the active DTCs.

      Does the scan tool display: B1036-19 WINDOW LIFTER SWITCHES ENABLE OVER CURRENT?

      Yes 

      • Go To  2

      No 

      • Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  2. ELIMINATE PASSENGER SIDE 
    1. With the scan tool, record and erase the DTCs.
    2. Turn the ignition off.
    3. Disconnect the Passenger Power Window Switch harness connector.
    4. Turn the ignition on.
    5. Try to operate the Driver Power Window several times.
    6. With the scan tool, read the active DTCs.

      Does the scan tool display; B1036-19 WINDOW LIFTER SWITCHES ENABLE OVER CURRENT?

      Yes 

      • Go To  3

      No

      Is the resistance below 3.0K Ohms?

      Yes 

      • Go To  4

      No 

      • Go To  5
  4. CHECK THE BODY CONTROL MODULE FOR A SHORT TO GROUND 
    1. Disconnect the Body Control Module C3 harness connector.
    2. Measure the resistance between ground and the Window Switch Supply circuit (Cavity 4) in the Driver Power Window Switch harness connector.

      Is the resistance below 3.0K Ohms?

      Yes 

      • Repair the short to ground in the Window Switch Supply circuit between the BCM C3 harness connector and the Driver or Passenger Window Switch harness connectors.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

    1. Measure the resistance between ground and the (Q337) Driver Window Switch Sense (Up) circuit (Cavity 1) in the Driver Power Window Switch harness connector.
    2. Measure the resistance between ground and the (Q339) Driver Window Switch Sense (Down) circuit (Cavity 2) in the Driver Power Window Switch harness connector.

      Is the resistance below 1000.0 Ohms in either or both circuits?

      Yes 

      • Go To  6

      No 

  6. CHECK THE BODY CONTROL MODULE FOR A SHORT TO GROUND 
    1. Disconnect the Body Control Module C3 harness connector.
