Why is my car fan not working properly?
Alternatively, connect the feed terminal on the motor direct to the battery positive terminal if the motor is fed via a thermo-switch. In either case, if there is a current at the motor, the motor is at fault. If the thermo-switch does not operate, the earthing point of the circuit may be faulty. Check that the earthing point is clean and tight.
Why is my condenser fan motor getting hot?
The most common problem associated with the condenser fan motor getting hot and then stopping is likely the fan capacitor. For a condenser the capacitor is typically a dual capacitor. The dual capacitor is a run capacitor that serves both the compressor and the condenser fan motor.
What to do when your AC Fan is not working?
Checked for incoming resistance ground to the blower, from the dash control switch and it works. Checked for battery at the blower, when the car is running. There is no battery to operate the blower. Rotated all the PDC relays around, they have the same ID, other than ABS pump.
What to do if your car fan is at fault?
If the fuses are intact, switch on the ignition and use a circuit tester to find if there is current at the motor terminals .

Can a car run without a radiator fan?
Yes, your car can still run without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to the engine’s performance and lifespan. Every time your engine overheats, you’re causing tremendous damage to the precious engine.
What should I do if my electric fan is not working?
With your pin and front motor mostly exposed, turn your fan over to inspect the opposite side of the motor case. On most fans, there will be a plastic vent that allows heat and air to escape from the motor. There will be screws on the back holding this case in place.
What happens if the fan on my radiator fails?
The most common symptom of a faulty cooling fan motor are cooling fans that do not come on. If the cooling fan motors burn out or fail, the cooling fans will be disabled. The cooling fan motors work together with the cooling fan blades to pull air through the radiator. If the motor fails the blades will not be able to spin or generate air flow.
What are the symptoms of a bad cooling fan motor?
The most common symptom of a faulty cooling fan motor are cooling fans that do not come on. If the cooling fan motors burn out or fail, the cooling fans will be disabled.
Why does my fan blower not come on?
If it does not come on then you might have a control board fan relay that is not sending 120 volts to the blower motor or a bad blower motor winding. You might try to change wires (speeds) on the blower motor to see if that fixes the problem.

When do you Know Your AC fan motor is bad?
If the compressor is working but the fan blades are not spinning, the motor is faulty. That’s your cue to turn the system off and call the pros to repair the AC fan motor. Replacing an HVAC motor is a job that can be done quickly once the problem is identified.
Why is my electric fan making so much noise?
Whether the blades aren’t spinning or the fan is making tons of noise, most issues with an electric fan are caused by poor lubrication or blockages in the vents. To solve most problems with an electric fan, disassemble the fan, lubricate the central pin and bearings, and clean out the vent and motor case.
What can be the problem with my electric cooling fan?
What could be the problem with my electric cooling fan? Answer: Usually, the problem is with the fan control module. Check for trouble codes, even if the check engine light is not on. On rare cases, the problem is traced back to the car’s computer.
What should I do if my radiator fan stops working?
Turn the air conditioning to the maximum setting – this should spark the cooling fan to immediately come on. In older cars, this typically takes about 15-20 minutes for the engine to reach the right temperature. If there’s a problem with the engine’s temperature, then this can damage the radiator.
What causes engine cooling fan not to work?
What Can Stop Your Fan From Working: Defective temperature switch, (ECT) sensor or other sensor Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.) Bad fan motor Defective fan control module
Why is my furnace blower not working?
One of the most common problems with furnace fans is a bad blower relay . The first thing to do is check the relay or voltage from the board. If no voltage is recorded, you will have to replace the board or the relay. If there is a battery, check if it is working properly. This is another common reason behind faulty blower fans.
Why is the engine cooling fan not working?
The temperature sensor determines when the radiator fan comes on by reading the cooling system temperature. If the sensor isn’t working, your fan won’t come on because it won’t know that the temperature is hot enough to require activation, which can frequently lead to overheating.
Why would a car fan not blow?
Problems like a fan clogged with dirt, a dead motor, a loose fan belt or a stuck wheel can all cause your blower to not work properly. These problems can keep the blower fan from blowing enough air out of your vents to keep you cool.
