Why is My Car AC Blowing Hot Air? - BlueDevil Products

Are you RECIRCULATING?

If after a few minutes it is still warm to hot air, try recharging the cooling system. Parts stores sell kits with instructions on how to do this.

Chances are you have a pretty fast freon leak, and the passenger side will be blowing warm within a few days. I have the same thing happen on a couple of my GM cars, except my leak is very slow; warm driver's side, cold passenger side.

You can try and top off the freon again, but I suspect you're going to have to take it to a shop to find the leak and get it fixed. Plan on spending some big dollars for the repair.

Good Luck.

It may just need recharged, go to a local repair shop and have the a/c system tested for leaks and recharged.

If you wanna do it yourself and save $$$$ go to a local parts store and get the recharge in a can... make sure it has leak sealer in it for good measure and follow instructions on can for installation. This will cost you $25 bucks and will save you from shop costs.

Blowing air across the windscreen does not necessarily clear away condensate from the inside. Water vapor condenses on any cool surface, and humid air blowing across a cool windscreen will result in more condensate on the windscreen. Often the air that blows across the windscreen is just humid AND heated, and doesn't solve the problem.
The air conditioner system performs two functions. Not only does it cool the air, it also extracts moisture, resulting in dryer air. Once the dried air is re-heated in the defroster system, it should allow the moisture on the windscreen to evaporate.
In other words, it sounds as though the defroster system is functioning properly.

the system is low on charge, it has a leak, repair the leak and recharge

CHECK YOUR CONDENSER IT MIGHT NOT BE GROUNDED. MINE DID THE SAME THING IT WOULD COME ON AND THE CONDENSER WOULD RUN FOR A FEW MIN. THEN KICK OFF AND NOT COME BACK ON MAKING IT BLOW COOL AND NOT COLD

Start by recharging your system. If you want to do it yourself. Most auto parts stores and hardware stores have recharge kits. Purchase a kit with a gauge to prevent overfilling.

I have a 2002 Jeep Liberty and after driving for about 30 minutes the air conditioner would start to blow hot air. The air conditioner clutch was sticking. I could hit the clutch and it would kick in and start to work. I went to Advance Auto and purchased a big spray can of electric motor cleaner and a big spray can of WD-40. I soaked the clutch with the electric motor cleaner, used the whole can, then soaked it with half a can of WD-40. The clutch has worked perfecty ever since.
