Hi all,

Please see the video in the link below and put your headset on to hear the noise:

There is a noise coming from under the hood when the AC is turned on and it is super annoying. The AC is cooling (not super good but it is cooling pretty well). I have been driving it like this for couple of months and I wonder if anyone can help find out where the problem stems from.

Here is a second video below I just recorded:
- I turn the AC on at 12th sec
- the disturbing noise comes when I press the gas pedal at 23rd sec
- as I keep pressing gas, there is that whining/brrring noise for a while and it takes a break (41st second to 47th second) and noise starts again at 47th sec. Then another break at 0.58 to 1:04, and starts brrrrring again.

To hear the noise better, can you put a headset on if you have one?

Sounds like your compressor is about to die. I don't know Jack about a/c systems but it sounds like bearings or something like when the bearings go in an electric motor.

I will try to get an engine stethoscope and see if I can figure out... thank you!
