My ongoing summer nightmare. Power Steering Pump died... then the Alternator and A/C stopped working.
Power Steering Pump replaced and a new alternator.

A/C was showing an open circuit. I replaced the A/C clutch and all was happy for about two weeks.
Then the A/C stopped cooling again. I am getting air from the blower. I checked the charge pressures and I think they are ok.

This time I have a new noise coming from what sounds like inside the dash.

The noise can occur when i start the engine with the A/C off. It will also come and go. And change pitch.

It sometimes sounds like bubbling/perculating. More like gas escaping from something, then just a straight bad bearing noise..
What is this?
