Front wiper high/low relay

WARNING: This page is about a different car, the 2006 Dodge Grand Caravan, 2006 Dodge Caravan, and 2006 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

The front wiper switch is a direct input to the BCM. The BCM sends a PCI Bus message to the FCM informing it to turn on the front wiper high/low relay. The relay switches power between the low speed and high speed windings of the wiper motor. The front wiper high/low relay is powered through low side control of the FCM. This circuit is electronically controlled and continuously monitored for malfunctions.
