Heater Relay

WARNING: This page is about a different car, the 1998 Isuzu Rodeo, 1998 Isuzu Amigo, and 1998 Honda Passport. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect heater fan relay. Ensure continuity exists between terminal No. 2 (White/Green wire) and terminal No. 4 (Black wire). Replace relay if circuit does not have continuity. Ensure there is no continuity between terminal No. 1 (Blue/Red wire) and terminal No. 5 (White/Red wire).
  2. Using jumper wires, connect battery voltage to terminal No. 2 (White/Green wire) and ground terminal No. 4 (Black wire). With relay activated, continuity should exist between terminals No. 1 and 5. Replace relay if continuity is not as specified.
