A/C making squeeling noise

When i turn on the A/C it starts a squeeling sound like a slipping or loose belt but the belt is ok. it looks like the pully on the compressor stops and goes and stops and goes. If the clutch is bad is it just an easy off and on replace. an idea of part cost. Thanks

    HI! it only squeels when i activate the A/C could it be just the clutch or clutch pully bering going out rather than the whole compressor, it looks as though the clutch or clutch pully is not spinning freely. I just dont want to take it in to a shop and get burned for a whole new compressor unit, it is still putting out cold air.

Is it squeeling all the time or just when the clutch is engaged. If it's when it's only when it's engaged then the compressor is in the process of locking up. When it's not engaged it spins fine?
If compressor is cutting off and on every few seconds, this points to a bad compressor also.
Or if it squeels all the time, your tension pully may be going bad. You can take the belt off and check it for play and ease of turning.

    I believe it's the compressor. The clutch pully is spinning ok until it is engaged when you turn the compressor on and then it's trying to turn the compressor.

2002 highlander--started squeeling from the belt area in Feb. Had belt replaced, was worn. It would squeel on starting then stop. Now turning on a/c makes it squeel. Fan works and after a little while

try cleaning the cogs that the belt runs around some times the belt puts a layer of rubber on them when the belt slips which makes the new belt slip if not could be a bearing in the pullys the belt runs around

Squeeling after replacing all belts and the tensioner pulley?

Still sounds like the belts, not much will cause that type of noise. You can completely remove all belts and start engine to see if noise is still there, no harm to engine to run it for a minute or two with no belts. You will know for sure then.

Compressor makes a loud squeeky noise

Could just be a worn belt or faulty or loose tensioner. Does it only make noise when AC compressor kicks in? If it's not a metallic sound, and sound more like a screech/squeel, then I'd look close at belt condition, and tension.

We changed the starter in my 2004 honda civic and it still won't turn over it makes a squealing noise and eventually it will start but sometimes takes multiple hours

When the vehicle starts and makes a squeeling noise that is your belt being loose, you need to tension that up,before you do that look and feel the Harmonic balances is it loose, because there is the crank sensor with a toner wheel that is responsible for correct timing so you need to make sure that harmonic balancer is not damage and that can be why squeel noise, that it is making and giving you such a hard time to start it up.So inspect to see if the Harmonic balancer has shifted.

My lexus rx300 new belts are squelling,battery light on,

It sounds like you have loose belt(s). When the A/C is turned on, it puts a big load on the belt, if it is loose and starts slipping and squeeling, then the alternator won't turn, so the battery runs down as you drive. Make sure all your belts and battery terminals are tight.

I have a 2001 Sonata. I have a squeeling pulley.

It sounds like you have a worn or streched belt making the sqeeling noise. Whenever you turn on a
device in the car that draws a fair amount of voltage
ie. a/c or headlights it will cause increased drag on
the alternator and if you have a loose/worn or glazed
belt, it can slip around the pully making the squeel.
To adjust the alt-a/c belt loosen the mounting bolts
on the tensioner, then use the adjuster bolt behind
the tensioner pully to loosen and tighten the belt.
Be sure to check the belt for cracks bald spots etc.
While the belt is loose spin the pullys to make sure
they all spin freely. Also I would replace the belt just
to be sure. Hope this helps

My kia spectra was making a loud squeeling noise and it has stopped but now my Air conditioner will not blow cold air ( only blowing warm to room temp. air) it my fan belt?

it sounds belt related. i am not sure if this vehicle has a seperate belt for the ac compressor, but if so, it sounds possible that the compressor seized and tore the belt off. have a look

2001 VW bug makes what sounds like a squealing noise when it starts. Sounds like it is coming from under the hood.

Sounds like the alternator belt is loose. Re-tension it then replace the belt as soon as possible as its likely to have been put under a lot of strain since it was slipping and causing the squeeling sound.

Squeeling when the car starts.

Your belts need replaced. Its the belt slipping that causes the squeel. Sometimes the idle pulley or belt tensioner will make the same noise if wore.
