Not likely. The belt may be old and stretched. A small adjustment to the tensioner or replacing the belt should help.

On our 2003 Tahoe there is a pump like squeak, umm, almost like bed springs when... Um, nevermind, when the ac power is on. Everything is working ok but sure is irritating. Seems to be getting louder.

If it is worse when reving the engine in park, your AC compressor is failing (common problem). The AC compressor, orifice tube, accumulator, belt tensioner and AC belt will need to be replaced and the AC system flushed before recharging.

you have to tighten the belt most likely if it squeals when you just first start it up and then it stops you can put some belt dressing on it and try that. See repair manual to tighten your belt either by using the tension er or some you can use the alternator adjustment to tighten up the belt as well.There could be other reasons as well but not as likely. They are 1. could be the bearings wearing out on one of your tension pulleys. 2. water pump might be going bad keep an eye on your temp. gauge. 3. air conditioner compressor could be shot or bearings going bad. and there are several others that are even more remote so hope one of these will help.

My air conditioning began making a rythmic squeaking noise when the AC was on. It has now quit blowing out of the front vents. It works on the feet, defrost vents and in the rear air. What could this be??

  1. Air conditioner system is discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
  2. Air conditioner compressor clutch not engaging. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

Squealing noise when I turn on a/c button

No, they are not all the same things, but they are all good suggestions. I am going to vote for the A/C clutch/compressor as my main candidate. The compressor is driven by the serpentine belt that drives all of the accesories on your motor. The A/C compressor only asks the engine for power when the A/C is on. When the A/C is off the pulley in front of the compressor is otherwise just spinning freely with no drag to the engine. When you turn the A/C on, it kicks in the electric clutch on your compressor, therefore making the sqeaking noise. It should also happen when you turn on the defrost. The squeaking noise is probably a bad clutch(not probable) or a bad compressor. Most of the time you can't buy the clutch seperate and will have to buy a new compressor. It's time to take it to the shop. Get a few quotes and take it to the Mechanic that you like the best. Also PLEASE rate my answer.If you didn't like my answer tell me, if you did tell me.

AC Belt squeaks on my 2002 Lexus es300

When belts squeak it's either from dryness wear or tension / tightness / looseness affecting alignment.

Check for tightness and you can spray with belt dressing and try some WD40 on the compressor pulley.

If none of that doesn't stop it it very well could be the clutch or pulley is stiff from non use and could need replacing soon.

2003 subaru forester makes noise when airconditioner comes on. Is it the fan belt

What kind of sound? If it squeals then the fan belt needs tightening or replacing.
If the sound is the engine increasing in speed when the compressor engages then that's normal.
