Turn signals blinking fast 2002 Monte Carlo

2001 Chevy Monte Carlo

Why is the turn signals blinking fast at the front of the car but the rear lights do not come on?


This is normal for when there is a bulb failure. You should also notice the turn signal indicator on the dash flashing fast as well. Replacing the bulb that does not illuminate should fix the issue.

Turn Signal Lights

The TURN SIGNAL fuse in the LH I/P fuse block supplies ignition positive voltage to the hazard and turn signal lamp flasher assembly. The HAZ SW fuse in the RH I/P accessory wiring junction block also supplies battery positive voltage to the hazard and turn signal lamp flasher assembly. The turn signal lamps may activate only when the ignition switch is in the ON or ACCY position.

When the turn signal switch is placed in either the left or right position, current flows from the flasher module’s output to the turn signal switch assembly. The flasher module then sends an on-off voltage signal to either the left or the right turn signals and their instrument cluster (IPC) indicator. When you press the hazard switch, all the turn signal lamps and both of the IPC turn signal indicators will flash. The hazard and turn signal lamp flasher assembly is grounded at G201. The front turn signals are grounded at G101 and the rear turn signals are grounded at G302.
