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.

I had the same problem,mine was the door in the box that separates the heater core and condenser, part was $34.00, but had to remove the dash to get to it

    It is common for the blend door to break, but there is a clever way to get to it without pulling the dash, ! yes, that's right...because I did it myself in about an hour!

2008 dodge avenger stopped blowing cold air from one day to the next. My mom drove my car today and now it's now blowing cold air when it was driving just fine yesterday. What could it be?

It may be an electric issue somewhere in the circuit but it's going to have to be troubleshooted using a wiring diagram to find the problem.

check the coolant level. If it is low the first thing to stop working is the heater.

If it is that low there is something leaking. A pressure check of the cooling system should help find the leak.

A/c is not blowing cold air in front but air is cool in the rear.

Hey M, the pressure could be nothing but "hot air" and not freon... (I had this same problem!!) I let off a bunch of pressure..(nothing but clear hot air!!) ..using a small flat punch..on the low pressure side... if freon on comes out right away..stop.. if nothing but hot air comes out.. keep letting it out until freon comes out,,, When mine started letting out freon,, I quit and tried the A/C again... and it has been working fine since.. Just my recent experience!!!!

Air Conditioner on my 98 DeVille has been a little flacky for a long time. Sometimes would stop blowing throught A/C vents and instead blow through heater and defrost. After a few minutes it's alway gotten...

The paths through your climate system are controlled by blend & diversion doors that are controlled by your settings and actuated by vacuum 'motors.' If you live in a hot climate, you may have cracked vacuum hoses which can cause the kind of random air temp and mix you are having.
If you have never had any maintenance done that involves rubber products, it may be time to do it.

The ac stopped blowing cold air any suggestions as what it could be?

ok that could be a number of things.. first thing i would check if it does blow air and it just dont get cold is to recharge the ac system its self this can be bought at pretty much any dept sote like walmart k mart or your local auto parts store it may be out of freon btu with doign this you also need to knwo where to put it in at which id suggest a repiar manuel that can be bought also at your local parts store like advanced auto zone ect for your type car if that dotn help you could have a bad compressor for the ac system.. if it dont blow any air at all more than likely your blower has gone bad and will need to be replaced .. i assume youve checked all vacume hoses as well prior to this if not check those as well and make sure they all are properly connected and secure

Today the A/C stopped blowing cold air yesterday it was fine, Nothing but hot air was coming our of vents

Look for leaks around the A/C hoses and compressor. You may just be low on Freon. When the pressure in your lines (amount of gas in your ac lines) is low, the ac will just cutout hence blowing hot air. try adding some freon.
