A/C whistle

Hi
When I shut off my 2003 Astro 4.3 v-6 after running A/C, I get a high pitched whistle.What could cause this?
Also rear a/c blows, but blows warm.Does rear have it's own blower motor,drier etc.? Last time a/c was worked on was about 2 years ago for recharge/ leak fixed.Still blows ice cold.High speed on fan inoperative also-possibly relay or resistor?Thanks in advance for any help offered.
