2003 Chevy Malibu: clutch..engages..it still blows out hot air

Resolved Question:

I have a 2003 Chevy Malibu, and AC is blowing out how air.

The AC Compressor clutch engages when the AC is turned on, and the refrigerant pressure is in the green. Yet it still blows out hot air. My Car repair manual doesn't give any ideas on what to check beyond these two things. Are there any things that I can check before having to take it to a mechanic?

when its running with the air on does it drip water under the car and if you where to touch the a/c lines are they both warm or one warm and one cold

The evaporator housing drain tube does not appear to be dripping water, and both AC lines are warm.

well if both lines are warm either it doesn't have enough freon in it or there is a compressor or expansion valve problem i would recommend getting it charge by a service center they weigh the refrigerant to be sure it has the correct amount the charge kits you buy don't always work correctly

 

we see this on a regular bases and a regular charge fixes it
