Hazard Lamps Inoperative P72
Circuit Description
Voltage is supplied at all times through the STOP-HAZ fuse and the hazard flasher to the normally open contact of the hazard switch in the turn signal/hazard switch. With the hazard switch in "HAZARD FLASH," voltage is supplied to both front and rear turn signal lights. All of the turn signal lights flash on and off.
The front sidemarker lights flash in "HAZARD FLASH," as in "TURN RIGHT" and "TURN LEFT," if the hazard switch is in OFF. They flash on when the hazard lights are on. If the headlight switch is in "HEAD" or "PARK," they flash on when the hazard lights are off, and off when the hazard lights are on.
