Default A\C Issues

2000 S type 3.0
My A\C does not blow cold air. The compressor is turning and the Freon pressure is about 40 psi low side. When I turn on the heater the air gets noticeable hotter. When the ac is "on" I hear a hissing noise from the dash. As I increase RPM the air gets slightly cooler.

You could have a problem with your DCCV valve not closing.
