Turn Signals: Description and Operation

When the ignition switch is turned to the RUN position, battery voltage is applied to the hazard switch from the backup/turn fuse through CKT 239. This battery voltage is then applied to the headlamp/turn signal switch through CKT 16.

During a left hand turn, battery voltage is applied to CKT 14, which in turn supplies voltage to the left front park turn lamp through the underhood fuse block, to the left rear turn lamp through the left instrument panel fuse block and the instrument cluster.

During a right hand turn, battery voltage is applied to CKT 15, which in turn supplies voltage to the Left Instrument Panel Fuse Block (LIPFB). Battery voltage flows through the LIPFB to the right front park turn lamp through the underhood fuse block, to the right rear turn lamp and the instrument cluster.

The front park/turn lamps ground through CKT 150 to the forward lamp splice pack. The rear turn lamps ground through CKT 650 to the rear body splice pack.
