Radiator Fan

WARNING: This page is about a different car, the 1994 Suzuki Swift. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check cooling system fluid level. Start and run engine. Ensure coolant temperature is less than 199°F (93°C). If cooling fan operates, go to next step. If cooling fan does not operate, go to step 3).
  2. Disconnect cooling fan thermoswitch, located near distributor. See Fig 1. If cooling fan stops running, replace cooling fan thermoswitch. If cooling fan continues to operate after cooling fan thermoswitch is disconnected, check for short to voltage in Blue wire between cooling fan thermoswitch and cooling fan motor relay. If cooling fan still runs, check Blue/Red wire between cooling fan relay and cooling fan for short to voltage.

  3. If cooling fan does not operate with coolant temperature less than 199°F (93°C), run engine until coolant temperature is more than 208°F (98°C). Feel radiator hoses for proper thermostat operation. If cooling fan operates, system is okay. If cooling fan does not operate, check fuse link "B" and IGN fuse in fuse block. If fuses are okay and cooling fan does not operate, go to next step.
  4. With cooling fan thermoswitch connector disconnected, connect a fused jumper wire between thermoswitch harness connector terminals (Black/White and Blue wires). If cooling fan operates with ignition on, replace cooling fan thermoswitch. If cooling fan does not operate, go to next step.
  5. Turn ignition off. Using a Digital Volt Ohmmeter (DVOM), check for continuity between Black (ground) wire of fan motor connector and ground. If continuity is present, go to next step. If continuity is not present, repair open or bad ground connection at Black (ground) wire. Ground connection is located on left front inner fender. See Fig 2.

  6. With engine running and fan thermoswitch terminals jumped, use a test light to backprobe cooling fan motor connector Blue wire. If test light glows, replace cooling fan motor. If test light does not glow, go to next step.
  7. Using test light, probe cooling fan thermoswitch connector Black/White wire. If test light does not glow, repair open in Black/White wire between cooling fan thermoswitch and junction block connector. Junction block is located behind left side of instrument panel. See Fig 3. If test light glows, check for voltage at fan relay connector terminal No. 1 (Blue wire). Go to COOLING FAN RELAY.
