Hazard Flasher Switch Test
- Check for blown hazard flasher fuse. Check hazard flasher for continuity. Hazard flasher is located at fuse block, under left dash. With hazard flasher removed, connect fused jumper wire between flasher terminals in fuse block. Set hazard flasher switch to ON position. Parking/turn-signal lights should come on and remain on.
- If lights do not come on, remove hazard flasher switch. On Mustang, hazard flasher switch is located at right side of instrument cluster. See HAZARD FLASHER SWITCH R & I under REMOVAL & INSTALLATION. For other models, see appropriate STEERING COLUMN SWITCHES article in the ACCESSORIES/SAFETY EQUIP Section. Ensure battery voltage is present at White/Red wire terminal of hazard flasher switch connector.
- If voltage does not exist, check White/Red wire for open. If voltage exists at White/Red wire terminal of hazard flasher switch connector, remove switch from connector. Set switch to ON position. Using DVOM, ensure continuity exists between all terminals except Orange/Yellow and Light Blue wire terminals. If continuity is not as described, replace switch.
