noise coming from passenger side engine
So, I have no idea what this could be. It seems to sound like a sort of high pitch noise coming from where the a/c dryer is at. It starts when the engine is warm and what alleviates it is accelerating then it goes quiet. Any ideas? Or what information more do you need so that you can help me?

Inspect your vacuum lines.
Your Heater controls vacuum reservoir will look like a black plastic sphere, mounted to the top of the PS inner fender liner. Pretty much directly under and forward of the air filter box. Give those two lines to/from that reservoira good look, they tend to crack in half and whistle. That would be a vacuum leak.
It should also affect the operation of the vents in the dash, making them only flow air out of the defrost. That's my best guess without being able to hear it, but it could be any of the vacuum lines.
