becoming concernedI have a 2014 cruze ... has anyone experienced a loud rattle noise under the hood that gets significantly louder when the AC is on? I have replaced the AC unit but still did not change. Also getting code P1101 off and on from time to time.
It's almost impossible to diagnose noises over the internet.Hi Jll
Agreed on the comment ...but you cant spin any of those components (without the belt applied) at a high enough RPM to duplicate the noise. And non of them had significant play at the pulleys to indicate bad bearings. So I replaced the unit that transmitted the noise the loudest. At this point its just throwing parts and money at the problem. I was hoping someone in the forum had encountered this to help in the next step.
