Turn Signal Lamps

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The TURN fuse in the fuse block - instrument panel (I/P) provides ignition positive voltage to the flasher module. The turn signal lamps may only be activated with the ignition switch in the ON position. When the turn signal switch is placed in either the left or right position, current flow is from the flasher module output to the turn signal switch assembly. The flasher module then sends an ON-OFF voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator.
