Description - Turn Signal System
WARNING: This page is about a different car, the 2004 Dodge Grand Caravan, 2004 Dodge Caravan, and 2004 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
The turn signals are actuated with a lever on Multi-Function Switch, located on the left side of the steering wheel. The signals are automatically turned off by a canceling cam (two lobes molded to the clock spring mechanism). The cam comes in contact with the cancel actuator on the turn signal (multi-function) switch assembly. Either cam lobe, pushing on the cancel actuator, returns the switch to the OFF position. The multi-function switch is a resistive MUX switch that feeds inputs to the BCM.
