How to detect the motor of the car radiator fan

With the continuous improvement of living standards, we have also begun to assume all responsibilities for car maintenance and keep the car in good running condition.

 

The car radiator fan is an important component under the hood, and it also helps air circulation throughout the passenger cabin. The blower motor is also responsible for dispersing the hot air output from the engine. When the blower motor does not work, your car may have a higher temperature, especially in heavy traffic or in hot weather. You need to ensure that your water tank cooling fan is working in good conditions to ensure safety.

 

(1) Check the fuse. Open the engine bay and fuse box of your car. Remove the fan fuse and replace it with a similarly rated fuse. Turn on the engine and observe whether the fan is running. If it is a new fuse, the problem may be a short circuit. Another possible cause of the problem is that the fan motor brush is too dirty.

 

(2) Eliminate motor mounting. If the fuse is working properly, then do a visual inspection of the motor. Check for any loose wires. If the wire is good, find out the jumper and hook of the motor. One wire is connected to the ground and the other wire is connected to the power source. If the motor doesn't work, then it needs to be replaced.

 

(3) Listen to the sound generated by the sound motor. Essentially, a normal blower motor produces sound. When there is idle for normal operation, listen to the sound of the blower motor of the car. Since most cars are soundproof, open your window and listen carefully to the sound coming from the engine. If you don't hear the fan running, then the fan may be damaged. It could also mean a blown fuse, bad resistor, or damaged wiring.

 

Feel the air coming out of the vent. If both the fuse and the motor are operating properly, turn on the pressure device. Feel the vents and check if there is air coming out. Turn on the air conditioner and check again if there is air. If the motor is running but no air is flowing out, it may be that the motor is blocked.

 

(4) Check the air flow. You can use a diagnostic tool to check the air flow. This is usually available at taxi supply stores. Finally, you still need to refer to the repair manual to check the code for errors.

 

 A defective fan motor will cause your heating and air conditioning system to malfunction. This will bring a lot of discomfort to passengers, especially in extreme weather. Include the air conditioning system test in your car's regular maintenance service schedule.
