High pitched squeal when defroster is on

There is a high-pitched squeal or chirp when I have the defroster on. Not your typical belt slipping squeak. Occasionally after driving with the defroster on, I can smell something hot, like burning rubber. Can this be resolved by a new belt or could something be wrong with the pulleys?

Sounds like your ac compressor is failing, fix it before your belt breaks and leaves you stranded.

I have a 95 Buick Regal.It makes a noise when running ,but if take the belt off it stops.


it depends what kind of noise, if its a licking noise the pulleys that the belt is being turned by could be bad (belt tensioner pulley ,Idler pulley etc.) if its a squealing sound like a high pitched whistle or like a rubber heal screeching on a tile floor constantly the belt is no good there is fabric on the inside of the belt and when it wears away you will get the chirp or squealing /screeching sound from this. inspection of that belt will tell you look at the grooves if looks like shiny rubber you found it if it doesn't and the fabric is there then a pulley is the problem bad bearing can make the belt slip resulting in the squealing good luck LATER MAN!

I've recently noticed that my 1996 v6 vs commodore has a high pitch squeal while accelerating and there seems to be no power behind it anymore either.


I would suggest that you check all units being driven by the belt as the squeal is from something not turning freely and making the belt slip on the crankshaft pulley or slip over what is seizing up.

High pitched squeal while driving


Most likely a belt slipping!

Squeaking when starting up.


If this is a high pitched squealing sound, then check the condition and adjustment of your engine's rubber drive belts.
If these have become stiff or worn, then they can begin to cause this noise, especially when starting from cold.

The belt in my 01 Dodge Dakota squeals badly. Started when I had my power steering pump replaced. I tried changing the belt and the tensioner, but still squeals. Is it possible the pulley on the power...


excess mechanical drag from the pump can cause the belt to slip and squeal, but before focusing on the pump I'd check the condition, tension and alignment of the belt. I might even try cleaning all the pulleys with an aerosol brake cleaner and install a new belt, particularly if the current one has more than 50,000 miles on it. It might be that the squeal is coming from or caused by a different belt-driven accessory.
A more typical noise from a power-steering pump is a high-pitched whine, not a squeal. Usually, if the steering wheel is stationary, meaning that the steering rack is not "asking" for assistance from the high-pressure fluid from the pump, there's little or no noise

Battery light comes on when it rains outside.


The surpinetine belt is slipping on the alternator. A high pitch squeal can sometimes also be heard, because rain water is making the worn belt slip. So replace the belt first. Other possibilities are the idler tensioner might be weak, or worst case is the alternator itself. Also check if your battery cable connections are clean and tightened, because the battery may not be getting a proper charge.

Nissan maxima 00 AC belt squeals for a moment and it goes away. If I turn on AC, lights, defrost, the belt squeals. It does not happen at high speed.


this means your belt needs to be tightend, if its not at the proper tension it will squeak at low speeds, especially when you first start your vehicle, and if you turn on your ac.

2003 Lancer ES High pitch squeal and constant squeak


Shortly after replacing the serpentine belt in my lancer, the same thing happened. It is NOT the timing belt. Belts squeal when they slip. If your timing belt slipped it would cause your car to run funny.

have somebody check the belt for wear (or do it yourself), replace if necessary. If it doesn't need replacement, just tighten it.

If you have the 4cyl engine that I have, the tightening is kind of a pain in the ****. Not a great design by mitsubishi. There's a pulley near the front right corner of the engine in front of the alternator. the belt should be running around this pulley GROOVE SIDE OUT. This is the tension pulley.

To tighten:
1) Lightly loosen the bolt in the center of the pulley (slightly loosen, DO NOT REMOVE).
2) Under that pulley there's another bolt. You can see that the bolt goes through a piece of metal
attached to the back of the pulley. Figure out which way you need to turn the bolt to move the
pulley toward the front of the car. (i don't remember if it's right hand thread, or left hand) This
puts extra tension on the belt. You probably don't need much. Over tensioning the belt can
cause pulley bearing failure. If you haven't done this work before, ask someone for
help
. It's better to tighten a little bit, a few times rather than overtighten once.
3) Don't forget to ReTighten the bolt in the center of the pulley.

If there's lots of cracks and pieces missing on the ribs or grooves of the belt you should replace it first.

Happy repairing,
Cliff
