Hazard Warning Lamps: Description and Operation

HAZARD LAMPS

MECHANICAL SYSTEM OPERATION
The hazard switch is located above the heater control assembly and controls the operation of the hazard lamp circuit. Pressing the hazard switch to the ON position will cause the turn/hazard signal relay to disengage the turn signal circuit and engage the hazard lamp circuit. This causes both turn indicators in the instrument cluster assembly to flash on and off along with all exterior turn signal lamps. The hazard lamp circuit will operate regardless of the position of the ignition switch. Press the hazard switch a second time in order to turn the hazard lamps off. Turning the hazard switch off disengages the hazard lamp circuit and returns the turn/hazard signal relay to the turn signal mode.

Refer to Hazard Warning Switch Replacement in Instrument Panel, Gages, and Console for hazard switch removal and installation procedures.

CIRCUIT OPERATION
Voltage is applied from Gage fuse to the flasher relay. When turned to the on position ground is provided to Cavity 8 of the flasher relay. Current is then provided to the flashers turning them on. The hazard lamps are individually grounded.

The following lamps are turned on when the hazard switch is switched to the ON position:
- The left and right front turn lamp
- The left and right rear turn lamp
- The left and right indicator lamp
