AC whining noise.

https://youtu.be/A7Viya-uRrc

If you click or copy that link I have video and the noise I’m hearing. It’s louder in person. This is a 2006 rubicon, and only makes this noise when the AC is on. Once you hear the compressor click, the “howl” starts. It has a slight tick now too. Uhhgh.


Any idea where to start with the howling? I can’t dial in on where it is exactly.

It’s coming from the AC compressor. Whenever it engages is when the “humming” starts. It clicks on and off every 5 or so seconds. I read this to be normal. I also read this to be a problem. It blows cold air and everything seems to be working fine for now.

I'll bite. I can hear the compressor cycling, but it doesn't sound overly loud on the video.


Your compressor clutch is working and the noise doesn't sound like belt whine which may indicate that the compressor is becoming hard to turn. The compressor may be getting old or the system is low on oil.


Unless you've recently had the AC serviced, I'd suggest waiting for something to fail before worrying too much about it. It may be the compressor getting old or something going on in you throttle body (Idle Air Control Valve opens and closes a little bit every time the AC cycles on and off).


Sorry. No definite answers for you.

No worries. Thanks for input. I’m gonna let it sit and when it goes so be it.
