How do I fix my radiator fan not working?
If the fan is not working even when the car is overheating, there might be a wiring issue or a bad connection. Check the wirings going to the radiator fan from the control unit or relay. Check in the connector plugs for any signs of corrosion. Also, check the connector plugs at the relay and control unit.
What can cause a cooling fan not to come on?
Six things may prevent an electric cooling fan from coming on:
- Defective temperature switch, coolant 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.
Can I drive car if radiator fan is not working?
Yes, you can drive your car without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to its performance, and every time your engine overheats, you cause damage.
Can I drive with a bad radiator fan?
However, you should never drive with a failing radiator fan. If the fan fails to bring in cool air to the engine, you could cause severe damage to the motor as it overheats. The expense you will pay to replace the engine far outweighs the cost of a bad radiator fan.
Does radiator fan come on with AC?
The condenser fan (if it has a dedicated fan) or the radiator fan most always comes in (with AC on) when the compressor discharge pressure (or, alternatively, the liquid line one; look for where a sensor or a switch is located on the high pressure line) rises over an operative threshold.
How do you test a radiator fan motor?
How to Test Radiator Fan with Car Battery
- Find the cooling fan next to the radiator or use your car manual to locate it.
- Unplug the connector.
- Use jumper wires to power the motor directly by connecting it to the car battery.
- If the motor spins it’s in good condition and the problem is either a blown fuse or bad relay.
What happens when radiator fan goes out?
If the cooling fan motor fails, the blades don’t spin and they don’t generate air flow. At that point, the engine temperature continues to climb until your engine overheats. Once your engine overheats, you get other warning lights to come on indicating the problem.
Can you drive a car with no cooling fan?
Should radiator fan turn on when AC is on?
When the AC compressor is activated, it is actually expected that the radiator fan runs. For instance, the radiator fan is needed when the temperature sensor of the cooling fluid in the lower tank reaches approximately 212F.
