How to test fan module control box ? ms908p scanner: amzn.to 2lci9agin this video we will demonstrate how to test radiator fan and radiator fan con. To test a fan motor, unplug the electrical connector at the motor and use fused jumper wires to connect battery power and ground directly to the fan. if the fan does not operate, replace the motor. 2. if the motor tests ok, check the cooling fan thermo switch, located at the bottom of the radiator on the driver's side.
This is how you can test a radiator or coolant fan switch without removing the sensor from the vehicle. this will also show how you can bypass the switch ent. Step 2: check for visible damage. step 3: inspect the fan’s wiring and connections. step 4: test the fan relay and fuses. step 5: perform a continuity test on the fan motor. step 6: test the radiator fan with a direct power source. test the radiator fan with the engine running. How to test your radiator fan with 12 volts directly from the battery. you can do this test with the fan installed in the car or outside the car it does not. Step 1: check the radiator fan type. check if the radiator fan is manual or electric. the manual radiator fan is bolted to the water pump and runs on the same belt as the water pump. the electric radiator has wires that connect to the car’s electrical system. to check the electric radiator fan, start the car and bring it up to a temperature.

If there is a spike in amperage or the motor is failing, the fuse could blow. you can replace the fuse and hope it was just a glitch. however, if the fuse continues to blow, there’s a bigger problem occurring. 3. vehicle overheating. the purpose of the radiator fan is to cool the vehicle.
