Turn Signal/Hazard Flasher
Turn Signal/Hazard Relay Input Test
1. Remove the driver's under-dash fuse/relay box (see page 22-86).
2. Remove the turn signal/hazard relay (A) from the driver's under-dash fuse/relay box (B).
3. Inspect the relay and fuse/relay box socket terminals to be sure they are all making good contact.
• If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, go to step 4.
4. Make these input tests at the fuse/relay box.
• If any test indicates a problem, find and correct the cause, then recheck the system.
• If all the input tests prove OK, the turn signal/hazard relay must be faulty; replace it.
