Power Windows - Inoperative - Passenger Door
TEST DESCRIPTIONSteps 1-4:
Steps 5-12:
Steps 13-22:
The Number(s) below refer to the step number(s) on the diagnostic table.
3. Determines if the failure may be on the window switch side of the door module (inputs), or on the window motor and motor control circuits side of the door module (outputs).
4. Checks to see that the door module associated with the inoperative window recognizes the switch input.
Enabling the headlamps in this step eliminates the possibility of the window switch using an alternative path to ground through the switch illumination circuit, which could cause the scan tool to display incorrect window switch states.
5. Eliminates the door module battery positive voltage supply and ground circuits (associated with module connector C3 for the passenger front door module, or, associated with module connector C2 for a rear door module) as the cause.
9. Eliminates the window switch as the cause of the malfunction.
If the 3 amp fuse of the jumper opens when the jumper is connected, test the signal circuit of the inoperative state for a short to battery positive voltage.
13. Eliminates the switch ground circuit as the cause.
14. Eliminates the switch signal circuit as the cause.
