Pressure switch for AC
#12
With the vehicle off, blow air through the condenser. If you can replicate a similar sound, you have loose fins or possibly debris stuck in the fins.

Finally found the problem. Changed out the pressure switch anyways since I had to get in there. On my SS the inter cooler piping was changed to an aftermarket which is apparently bigger than stock. There is a vacuum tube and sensor at the bottom before entering into the inter cooler which is pushed tight against the factory pressure switch plug and has rubbed a wire bare. We separated the wires and siliconed it up and it works great now. Will fix it the right way later when I take off the front end to install new. Thanks for all the help.
