Cooling Fan Relay(s)

INSPECT RELAY CONTINUITY






1. Using an ohmmeter, check that there is continuity between terminals 1 and 2.
- If there is no continuity, replace the relay.
2. Check that there is continuity between terminals 3 and 4.
- If there is no continuity, replace the relay.

INSPECT RELAY OPERATION






1. Apply battery positive voltage across terminals 1 and 2.
2. Using an ohmmeter, check that there is no continuity between terminals 3 and 4.
- If there is continuity, replace the relay.
