Why is my engine whirring?
When you accelerate, the engine makes a whirring noise. The more you accelerate, the more the whirring increases. It’s time to get your car in for a checkup! There might be a number of reasons for this, including a bad water pump, low levels of power steering fluid, and a bad air conditioner compressor.
What should I do if my car fan won’t turn on?
On modern vehicles, a bad sensor usually triggers the check engine light. Scan the computer for trouble codes, if necessary. If the fan fails to come on, first check for a fan blown fuse or triggered breaker. On older vehicle models, you may have a fusible link in the circuit.
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.
Do you have an electric cooling fan in your car?
If the cooling system in your vehicle uses an electric cooling fan, most likely you have a transversal (sideways) mounted engine. However, some longitudinal (front to rear) mounted engines use the electric fan as well, but they usually have an engine-powered cooling fan.
Why does the engine cooling fan not turn off?
I was wondering if anyone knows why the engine cooling fan does not go off when you turn engine off. We had to pull the fuse that is under hood on top of battery. Once we pulled it, it went off, but when we put it back in the fan started up again. Any and all replies would be greatly appreciated. 50 people found this helpful.
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 is my car AC not blowing or car fan not working?
It sounds like your blower motor or fan is damaged. The noise you heard was probably the fan blades hitting the side of your ventilation ducts and it suddenly stopped when either the motor failed or the fan finally got stuck. Replacing the blower motor and possibly fan should get you back to having AC!
How does a car air conditioner fan work?
Most vehicles today have one multi-speed fan that blows air through a series of ducts and vents based on the driver’s selection in their climate control system. These different speeds are usually controlled through a set of resistors or a small computer module which is controlled by the fan switch.
