I would replace the AC compressor cycling switch it may be sticking have seen it a number of times. The switch is located in the receiver dryer on the passenger side of the engine compartment. See picture below.
If this isn't the problem the AC compressor relay may also cause this, flip a coin.
I have the same problem starting on mine. The first answer above is totally wrong. The actuators that control the doors are 12 volt electric no vacuum. There are three actuators on the drivers side under the panel by the gas pedal. I haven't worked on mine so I can't tell you which one it is but all are the same part and interchangeable take a new one and try it in each position until it works.There is one in the center console and one under the passenger side by the blower motor the console is for rear HVAC and the passenger one is for recirculation after installation it will have to be calibrated . Turn ignition to ON not start push the power button and the recirculation button at the same time hold for 5 seconds lights should start flashing leave it for two minutes or the lights stop flashing. If they don't stop recalibrate until they do. If they won't stop drive for eight miles and it will stop on it own. (but not fixed)
This problem is likely due to a failed part called the blend door, this door has an electric motor drive, to replace it requires the dash be removed form the car entirely. The blend door is a door that moves back and forth between the AC core and the Heater core to provide cold hot or a blend of air flows from both cores to give the desired temperature. Other issues can cause this and due to the cost or repair a through diagnostic should be done to confirm my guess is correct about the door being the problem.
On the central console is the A/C module. Inside A/C module are driver's side & passenger's side air flaps for mixing hot & cold air and directed air flows towards driver's side & passenger's side according to driver commands. The passenger's side flap for mixing hot & cold air according to driver commands is bad. Flaps are actuated by electrical step by step motors. Could be damaged the flap actuator (motor), the flap mechanism (blocked in "HOT" air position), and / or electrical supply wires. You must access the passenger's side flap for mixing hot & cold air, and see what happens when you command cold air to the driver's side: flap mechanism, flap actuator, supply wires, ... Repair & replace bad pieces and test the A/C system.
The drain for the evaporator is stopped up,use compressed air,like a air tank and a blow gun.The drain is directly below where the ac lines go into the firewall.If this was at all helpful,please rate,thank you.
You have to find the motor that controls the blend door and open it manually to find out which one is bad there are 3 blend doors on the HV/AC system one will be where the heater core is. The other will be between the vented air and AC? heating system then the third door will operate vents in dash and defrost condition. If you have someone operate them AC system heating system and watch the blend door motors, the one you find not moving will be the one that has the problem. They have vacuum and electrical motors, if it is a acuum motor you can move the door manually with your hand, if it's electric you will have to disconnect the rod by removing the pinch clip off of the rod.
Yeah Ron, the flap that covers the heater core is open and when you're moving the air is pushed over the heater core and into the cab your in. Possibly just a vacuum line of that controls said flap. Check all vacuum lines for good proper connection to these flaps because all of them are vacuum actuated.
