went to fire up my air today and i got nothing but warm air blowing thru the vents. so i popped my hood and turned on the a/c and the clutch on the compressor did not engage.checked the fuse on the side of the dash and it was ok. should i assume that the relay is bad or look somewhere else?

Might be your out of freon and low pressure switch is keeping the clutch from engaging.

checked my refrigerant with a gauge and it seems to be under pressure. my gauge has a blue saftey zone on it and i am within the correct range.
