I have a 09 toyota camry se and I had been hearing at first a squealing noise when cranking up the car but it didn't last long. So then I was experiencing an issue with my headlights driving in the and the motor would jerk a little bit. So I did some research and found out that it could be the serpentine belt so I replaced that. Well now I noticed when I turn the ac on I hear a clicking noise. Could my tensioner be going bad or could it be the ac compressor? I do get good cold air from the ac.

 

When changing the belt did you spin test all the pulleys for rotational freedom?

Use a section of rubber hose as a stethoscope to narrow down the noise area.

 

The pully did spin ok, I'll try the hose idea.
Thank you
