Darn Turn Signals !!

This may be a strange question but do your backup lights work? According to the wiring diagram for your car, the backup lights are fed from the same circuit as the turn signal circuit hot feed. If you trace where the radio and heater get their power (black wire), a white wire also connects to that circuit. That wire runs the backup light feed as well the turn signal flasher hot feed. The turn signal flasher should have a red and black wire connected. The red comes from the turn signal switch and the black is the switched hot feed from the ignition switch
