Normal Operation

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The indicator flasher relay receives battery voltage through circuit 10 (LG/RD). The indicator flasher provides voltage to the multifunction switch through circuit 385 (WH/RD). Circuit 57 (BK) provides ground for the indicator flasher. When the hazard switch is turned on, the multifunction switch routes voltage to the turn/hazard lamps. The timed on/off cycle is determined in the indicator flasher relay and is set to flash approximately 80 times per minute when the hazard switch is turned on.
