2. Remove and check the cooling fan motor relay. If the relay is OK, proceed to step number 3, if the relay is faulty, it should be replaced.
3. Measure the voltage between the pin "2" cooling fan motor relay connector and ground. If the voltage matches the battery voltage, proceed to step 4, if it does not match, replace the relay box.
4. Short the leads "1" And "2" cooling fan motor relay connector. If the fan rotates, proceed to point #9, if it does not rotate, proceed to point #5.
5. Open the pins "1" And "2" cooling fan motor relay connector.
6. Disconnect the radiator fan motor connector.
7. Check the continuity between the output "1" cooling fan motor relay connector and output "2" radiator fan motor connector. If there is continuity between the terminals, go to step #8. If there is no continuity, repair the open between the radiator fan and the cooling fan motor relay.
8. Check the continuity between the output "1" radiator fan motor connector and ground. If there is continuity, replace the radiator fan; if there is no continuity, repair the open ground wire "G330" or open, radiator fan ground circuit.
9. Open the pins "1" And "2" cooling fan motor relay connector.
10. Turn the ignition key to position "ON".
11. Measure the voltage between the terminal "5" cooling fan motor relay connector and ground. If the voltage matches the battery voltage, check the wiring harness between the cooling fan motor relay and the ECM, otherwise replace the relay box.
