The numbers below refer to the step numbers on the diagnostic table.
This step inspects to see that the door module associated with the inoperative window recognizes the window switch input.
This step eliminates the door module battery positive voltage and ground circuits associated with door module connectors C1 as the cause.
This step begins to determine if the window motor control circuits, the window motor, or the door module outputs may be the cause of the malfunction.
This step eliminates the window switch Up signal circuit as the cause of the malfunction. The step also begins to determine if the window switch may be at fault.
If the 3-amp jumper wire fuse opens when the jumper wire is connected, the window switch Up signal circuit may be shorted to battery positive voltage.
This step determines if the window switch ground circuit is the cause of the malfunction. The step also continues to determine if the window switch may be at fault.
This step eliminates the window switch Down signal circuit as the cause of the malfunction. The step also continues to determine if the window switch may be at fault.
If the 3-amp jumper wire fuse opens when the jumper wire is connected, the window switch Down signal circuit may be shorted to battery positive voltage.
This step determines if the window switch is at fault, or if the cause of the malfunction is in the window switch Express signal circuit or door module.
If the 3-amp jumper wire fuse opens when the jumper wire is connected, the window switch Express signal circuit may be shorted to battery positive voltage.
