Turn Signal Lamps

WARNING: This page is about a different car, the 2002 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

Ignition positive voltage from the TURN fuse in the fuse block, is supplied to the turn signal switch. When the turn signal switch is in the normal position voltage is supplied to the hazard and turn signal lamp flasher assembly. The ground to the hazard and turn signal lamp flasher assembly is supplied from G200. The hazard and turn signal lamp flasher assembly applies a pulsating voltage to the turn/hazard flasher output circuit. The turn/hazard flasher output circuit is applied to the turn signal switch. When the turn signal switch is in the left or right turn position the pulsating voltage is applied to the corresponding rear turn lamps, the instrument cluster turn indicators, the HUD turn signal indicators and the front marker and turn lamps. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. The front turn signals are grounded at G101 and the rear turn signals are grounded at G302. The instrument cluster turn indicators are grounded at G200.
