Someone will need to find out if the compressor clutch is failing, or if it is loosing power due to a pressure switch or other problem. A faulty relay or switch could get hot and switch off power to the compressor.
You need to hook up a set of AC pressure gauges to the low side charging port and read the system pressures with the AC compressor turned on and running, it should be around 28-32 PSI. If the compressor press is correct you have some other problem like a broken air temperature control blend door inside the dash air ducting.
a bad relay will arc on the inside causing increased amp flow. Try replacing the ac relay. $23 for a compressor relay from rockauto.com. This all depends on which fuse is blowing. a wire shorting to ground will just as easily blow a fuse.
Blowing hot air when set to A/C is almost always a stuck blend door, dead blend door actuator, or a cracked or disconnected blend door actuator vacuum line. The blend door is inside the a/c ducting under the dash, but the actuator will be accessible outside the ducting.
If it's blowing air, even warm air, it's not the relay. Probably needs to be charged,(more freon in it)
Have the system checked, could also be a blend door under the dashboard not working, or the compressor. Without testing the system, it's hard to say what it is.
Your recycle door may have 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.
check the compressor with the ac running and make sure the compressor is kicking in and out in not the compressor might be bad or te clutch on te front of te compressor, sometimes u can get to much freon in them to i did it ounce
If not blowing air inside the indoor coil is froze up.
If so could be a plugged air filter, faulty indoor blower motor, or maybe low on refrigerant.
You will have to shut it down to defrost completely.
The outside unit has a fan and a compressor, both should be running.
If anything besides a plugged filter have an expert check it out.
