No Pusher Fan: Notes

NOTE: Test numbers refer to numbers on diagnostic charts.
  1. Test light should be on because relay harness terminals No. 85 and 87 have battery voltage with ignition on.
  2. Jumpering relay harness terminals No. 30 and 87 by-passes pusher fan relay. If pusher fan runs, pusher fan relay is faulty.
  3. Checks circuit No. 473 back to PCM. If circuit No. 473 is okay, pusher fan relay is bad.
  4. Checks wiring to pusher fan motor. If wiring is okay, problem is connections, pusher fan motor or motor ground.
