Question about Cars & Trucks
Many things. Could be bad thermostat. Head gasket out. Fan/blower relay bad/defective. Not enough antifreeze in cooling system. Check antifreeze for level and strength ith tester. Have to take radiator cap off first, but do it when vehicle is cold. Do you know how to change a thermostat? don't attempt if never done before. Pressure test cooling system or take to autozone/advance auto/o'riellys to have pressure tested. This will tell if your head gasket is blown. You can buy a cheap 5-ball antifreeze tester and check the coolant condition. One more solutions. Coolant system may have to be burped. Possible vapor lock in coolant system if antifreeze change recently and not burped properly.

you can get a recharge kit at Auto Zone, the car has to be runnung to fill it. . This is the first thing I would do, to see if it's out of freeon first.
Ask the Auto zone man to come out side and help you refill it. They will help if you ask.

See my posted question under 2001 Mercury Villager: "HEAT BLOWS COLD WHEN CAR IS IDLING" I got an answer from chuck943 about air pockets and it was very helpful.

I had same problem on 2000 Lesabre blowing cold on passenger and warm on driver. I fixed it by adding more freon even though it had 28 pounds of preasure. Now it works great!
