Without Air Conditioning

  1. Disconnect fan relay. Fan relay is mounted on left inner fender panel. Using a jumper wire with an in-line 25-amp fuse, supply battery voltage to fan relay connector terminal No. 4.
  2. If fan operates, motor is okay. Go to next step. If fan motor does not operate, check continuity between fan relay connector terminal No. 4 and body ground connections. If continuity exists, replace fan motor. If continuity does not exist, repair open and retest.
  3. With fan relay connector disconnected, turn ignition switch to the RUN position. Check continuity between fan relay connector terminal No. 5 and body ground connections. If continuity does not exist, repair open. If continuity exists, go to next step.
  4. Using a jumper wire with a 25-amp in-line fuse, jump across fan relay connector terminals No. 1 and No. 4. If fan motor operates, leave jumper wire connected and proceed to next step. If fan motor does not operate, repair fan relay fusible link.
  5. Check for battery voltage at cooling fan relay connector terminal No. 2. Connect a jumper wire across radiator coolant temperature switch connector. Radiator coolant temperature switch is located on radiator outlet tank above lower radiator hose. If fan does not operate, replace radiator coolant temperature switch.
