Test Description

The number below refers to the step number on the diagnostic table.

This step determines if the power window master switch lockout signal circuit may be shorted to battery positive voltage. Normally, with rear window lockout not enabled, this circuit is closed within the master window switch and rear windows are operational from their respective switches. When the lockout feature is enabled, the circuit is open and no voltage is available at the rear window switches. A short to voltage on this circuit would cause power to be supplied to the rear window switches regardless of the lockout switch status.
