This could mean your pump bearings are going bad.
A bad compressor belt can cause a whistling noise while running the air conditioner. A bad engine can also cause this noise.
the air conditioner shouldn't have anything to do with it. there could be a problem with your tires or your driving or your kid could be jumping on the seat
There are 2 fans that would be running while you are driving and that is normal... the compressor fan if you have the air conditioner running and the radiator fan runs to help keep the radiator cool while the engine is on.
No. Running an air conditioner on fan does not cost as much as running on cool.
There shouldn't be any danger of running without the air conditioner freon in it. Except for when it is really hot outside and you are sweating like crazy. (Just kidding)
You will use more gas when your air conditioner is running.
A worn serpentine belt will make a high-pitched squeal when the engine is running. The faster you go, the louder the high-pitched will become.
No. The air conditioner is driven by the engine crankshaft, so it will not turn if the engine is not running. Just so you know, you are wasting a lot of gas by driving around with your A/C engaged all the time.
Check to see if your condenser fan is running when a/c compressor kick on.
Air causes the whistling noise. I'm currently on a quest to eliminate the problem in my house (just had new water heater installed about a month ago, sounds like a choir of banshees when the water's running, toilets are flushed, washing machine or dishwasher are running,, etc.) When I figure out how to get the air out, I'll post a follow-up. In the meantime, at least you know what it is!
No. The ECM is a computer.
there is a leak in the compressor...
