Turn Signals: Description and Operation

TURN SIGNAL AND HAZARD LAMPS

The turn signal lamps may only be activated with the ignition switch in the ON position. When the turn signal switch lever is placed in either the left or right hand position, the respective turn signal lamps will flash. The Instrument Panel Cluster (IPC) turn signal indicator, either left or right will also flash.

When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators. The TURN-B/U fuse in the IP fuse block supplies battery positive voltage to the turn/hazard flasher. When the turn signal switch is placed in either the left or right position, a path to ground is applied through the left or right hand turn circuits. The turn hazard flasher then sends an on-off voltage to either the left turn signal output circuit or the right turn signal output circuit.

When the hazard switch is pressed, the hazard switch contacts close and a path to ground is applied for all of the turn signal input circuits of the turn/hazard flasher. The turn/hazard flasher then supplies battery positive voltage in an on-off flashing pattern to all the turn signal lamps. All the turn signal lamps and both turn indicators illuminate in the same flashing pattern.
