Question about Cars & Trucks
I noticed a few weeks ago my A/C pressure was low and not as cold. I had it on the highest setting and still didn't feel as cold as it should. Within a few days my A/C went from slightly blowing chilly air to slightly blowing hot air. Low on $$ so optimally wanna get a part and pay somebody outside of a shop to fix it. Any ideas???
The first thing to do would be go to your local auto parts store and buy an air conditioning recharge kit. Provided your vehicle isn't too old, they sell recharge kits that require no tools.
If their is a leak anywhere while you recharge, you will know.
Try recharging the air conditioning first, it is very simple and the kits come with simple instructions.
If there are no leaks, your A\C will blow cold air again. As for the pressure, if it continues to slightly blow air you may be looking at a new air compressor unit or a vaccum line. A new unit will run you anywhere from $200-$2000 dollars plus labor depending on the vehicle.
If the recharge works, at least you will have slightly blowing cold air rather than hot and you can continue that way until the unit fails.

There is only one A/C system split into 2 zones. Check the blend door actuator, it may have failed in one position or something may be jamming it. Also check the control panel in the dash, My 98 yukon did the same thing, no matter what temp you selected for the front it would blow at about 70 degrees. There is a circuit board in the control panel that gets corroded and one of the circuits controls blend door operations. Have a look.

If compressor isn't kicking in, check the connector atop the a/c accumulator, beside the coolant recover tank, in the engine compartment. That connector is atop a black bottle, and the connector goes to the low pressure switch. These switches do fail, and you can jump a wire across the connector terminals to see if the compressor comes on (engine running). As this circuit provides part of the ground path from the compressor clutch, if the switch is open, the compressor will never turn on. If the switch is failed, it can be replaced without opening the a/c system. Just disconnect the connector, unscrew the switch, replace it, and reconnect the connector.

You would have to measure the pressure to determine if it's pressurized correctly. The compressor won't run if it's low.
What happens when you push the a/c button? Can you hear/feel the compressor kick in? It seems like in most cases it's the compressor itself or the compressor clutch that goes. It's way too common in vw's...

Refrigerant is not your problem!!!!!!!!
Your recycle door has broken off and fallen over the suction duct to your blower. You can verify this by removing the blower under the dash on the passenger side. Reach up into the duct and if there is a plastic door obstructing the duct, it has broken off. With a little manuvering you can remove the broken door through this hole and you will have air again, just no control of inside or outside air. Dodge has redesigned the housing for this recycle door which is supposed to stop this from happening. The redesigned housing and door come as a unit from Dodge for about $30.00 and this includes the electric actuator. This requires removing the Dash to change the housing so if your not ready for several hours work, take it to a mechanic.

Had similar problem. The actuator that opens & closes the air blend door quit working. This is easy to see if you remove glove box. The actuator will move when you adjust the temp selector (do this while the heater is running).
