Turn Signals

CIRCUIT OPERATION
Power for the turn signals flows from the Power Distribution Center (PDC) to the ignition switch on circuit A1. The A1 circuit is protected by a 20 Amp fuse located in cavity 8 of the PDC. With the key in the ACCESSORY or RUN position, the ignition switch connects voltage from the A1 circuit to the A31 circuit.

Circuit A31 connects to the junction block and powers fuse 15. This is a 10 Amp fuse. From the fuse, circuit F13 supplies voltage to the combination flasher. The F13 circuit also supplies power to the windshield wipers and the rear window defogger relay.

Circuit A15 also supplies voltage to the combination flasher. This circuit is HOT at all times and is protected by a 20 Amp fuse located in cavity 6 of the PDC.

The L32 circuit connects between the combination flasher and the turn signal portion of the multi-function switch. Circuit L32 connects to a BUS bar internal to the switch that powers the turn signals and the hazard flasher.
