Hi!
It
appears we have an Air lock scenario and you will need to perform a
system Bleed.
Park
the vehicle on level ground, when cold remove coolant filler cap,
start engine and leave to idle, turn heater on full and blower to
max. When engine reaches operating temperature watch and listen near
coolant filler, keep clear as gurgling and hopefully a boil over
should occur. Top up with very warm coolant and wait as it may do it
again.
Check
for heat inside vehicle if warm replace coolant cap but keep an eye
on temperature gauge as the ~Air lock may have moved on from heater
matrix/core so proceedure needs to be carried out again from COLD.

The A/C system has a pressure switch will keep the A/C from running if the freon is low. It prevents damage to the A/C compressor from low freon.
My bet is you'll need to recharge the A/C system.
Take it to a garage and have them evacuate the system and refill with refrigerant. you have air and non condensibles in the refrigerant system.
SOURCE: saturn ac wont blow cold air
check cooling fan operation while ac on.If fan is working proper,will probably have stuck exspantion valve.
SOURCE: ac not working, blows hot air only. Recharged
Check the evaporator coil by sniffing the vents,floor is best, with your tester.
