Circuit Description
WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
The body control module (BCM) monitors the Windshield Wiper Switch Low signal circuit and performs the proper logic to activate the windshield wipers in the Low, Intermittent or Delay mode of operation. The BCM can discern if there is a malfunction on the Windshield Wiper Switch Low circuit. If the BCM detects that the circuit is shorted to B+, B- or the signal is corrupted the BCM sets DTC B3922 and the wipers will not function in the in the Low, Intermittent or Delayed modes. If this DTC is set as current, only the High mode of operation will be functional.
