What does it mean when your car fan wont turn on?
While it may be a matter of a simple cleaning and lubrication, it can also be a sign that your fan motor is wearing out or the fan blade bearings are ruined, in either of those cases you are better off buying a new fan. Before you spend the money doing that, try these simple solutions first.
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 . 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.
Why does my car fan fuse keep blowing?
If the test light lights up you know that there is a short in the wire between the relay and the cooling fan relay. Take a good visual examination of all the wires and connectors on the circuit. If a connector is loose fitting it can generate heat and cause the fuse to blow.
What does it mean when your engine won’t start?
Vapor lock doesn’t mean your engine doesn’t turn over, but your engine won’t start. Vapor lock is a fuel system problem, usually found on older cars with low-pressure fuel systems. When gasoline in the fuel lines or fuel pump turns from liquid to gas, it starves the engine of fuel and it stops running.
Can a car fan still run after the engine is turned off?
Then you notice the engine cooling fan is still running even though the car is turned off. It is ok for the engine cooling fan to keep running for a few minutes after turning off the car. Your car fan will run for a few minutes after you turn off the car then turn off. This is normal in many vehicles, such as BMW or Mercedes-Benz.
Why does my car not turn on when the engine is off?
A bad sensor will tell the car that everything is normal while the engine overheats. If your car’s fan does not turn freely by hand when the engine is off, then the fan motor is seized and needs to be replaced. Fans may fail to engage if the car’s system voltage is too low, as might be the case with a failing alternator.
Why are my cooling fans not turning on?
If the compressor is running long enough to build heat in the high side of the system, and the cooling fans don’t turn on, I would begin finding the fan relays and add power to the appropriate circuit to see if the fans turn on at all. This will require a wiring diagram.
Why does my car have a radiator fan?
You probably already know the purpose of the radiator and the cooling system in your car. When you are driving fast, the wind is passing through the radiator to cool the coolant down without issues, but when you are driving slow, there is no wind pushed through the radiator. This is why we use a radiator fan.
