Air Conditioner on 2003 Chevy venture Not Blowing Cold Air.

Pump is working, fuses are all good and gauge reades 45 psi of freon on low pressure side of system. Acts like there is a selonoid not opening or something. Can you Help?
Thank You David

at what rpm is the 45psi? Pressure on new models should be checked at 1500 rpm. Does it ever blow cold? If it blows cold at first and then stops, it could be freezing up. Or the blend doors could be stuck on the heat side....Lots of possibilities.
