Turn Signal Relay: Testing and Inspection

1. Remove the turn signal/hazard relay from the under-dash fuse/relay box.




2. 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, make the following input tests at the fuse/relay box socket.
- 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.
