("CAR OFF NOT RUNNING")Check the A/C pump to see if the clutch it clicking when the a/c is turned on (two people works best for this) if the wires to the pump are not broken or unplugged . This will make it blow hot air, or the pump clutch is rusted from sitting try to spray the clutch only tap on it little try to turn it try not spray the belt. When it turning retest starting the car check it BECARFUL of hot and moving part!! If the clutch really rusted badly will not move you might need a new or used A/C pump.
