Heyo!!! So I replaced the AC compressor in my 07' HCH about a week ago and since then my car has been making this strange buzzing/Vibrating noise, It sounds like it's coming from the passenger side closer to the compressor. The noise can only be heard from inside the car, no matter what it is not heard from outside. The noise is usually only heard after driving for a little bit, and happens when slowing down or sometimes when idling. Any help is appreciated!

How did you Solve this issue ! I kinda have the same

 

I honestly haven't fixed it. Since it has gotten colder I haven't been using AC. So the noise is gone because of that. But because the AC compressor hasn't been running I did confirm it was the AC compressor. What my theory is; when I installed the new AC compressor, I either put too much or not enough refrigerant in the system. I did replace the oil in the compressor. But that did not help the noise. Honestly I would try getting the HVAC and Recharge on the system, and see if that helps.
