I have the very same problem with my 99 Nissan Altima. I have replaced both the belt and the tension idler. I believe it may be the AC idler pulley.

The belt is the most likely culprit could also be the belt tension idler that puts tension to keep the belt adjusted

Screaming noise from ac no cold air


It sounds to me that your belt or tensioner is worn, if the noise goes away when the ac is off then it is just the belt slipping, it takes a lot of power to run the compressor and if the belt is worn it most likely slipping on the pully when you engage the clutch.

Squealing noise then tump when turning on heater 03 lincon navigator


Your AC compressor on the engine is the likely problem, either the pump is frozen up or the front bearing is frozen up, don't run the system or the belt will burn and fly off and strands you. Get this taken care of right away before winter. Have a local shop listen to the noise to confirm my guess as to the cause.

A loud noise when I turn on the AC and shift it to D or R.


What kind of noise? If it's like a squeal it is a lose belt. If it's more like a clunk it's the transmission shifting and you just happen to notice it more because of the higher RPM the motor is at with the AC on. Try getting the vehicle moving with out the AC on then turning it on after you are moving to see if you get the same sound. If it's a squeal you have a loose belt that needs replacement or tightening.

Squealing noise when a/c is turned on, then noise stops. Is this an a/c fan belt or something else? Would like to know what to expect when I go to auto mechanic.


Sounds like you might have a loose are worn fan belt. Specially if this is a V belt. With the hood up have someone turn the air conditioner on and watched the compressor clutch if it stops turning you might have a bad compressor. If it keeps turning in the squealing just goes away, you might just have a loose belt. Good luck.

Help! Air conditioner causes squeal soon after turned on


The ac is belt driven, If one of the belts are loose it will make a squealing noise. Turning on the air puts more strain on the belts. If this is the case all you would have to do is tighten the belt or belts. This would probably take a service tech just a few minutes. Probably under $100.00 dollars..........
