Hazard Warning Switch Test

Ensure HAZARD-HORN and/or TURN fuses are good. Ensure flasher is good. See TURN SIGNAL FLASHER LOCATION table. With hazard warning switch removed from dash, ensure voltage is at switch wiring harness connector terminal No. 8. See Fig 1. If voltage does not exist, check/repair fuses and wiring circuit. If voltage exists, disconnect switch from connector.
Using DVOM, ensure switch continuity exists between indicated terminals with switch in specified position. See HAZARD WARNING SWITCH CONTINUITY TEST table. If continuity is not as specified, replace switch. If continuity is as specified, check wiring circuit. See WIRING DIAGRAMS .
