COULD BE A FEW DIFFERENT THINGS. HAVE YOU TRIED TO SWAP THE A/C RELAY FOR ANOTHER? IT COULD BE A BAD ACCUMULATOR SWITCH OR A CLOGGED ORIFICE TUBE, OR A DEFECTIVE LOW PRESSURE CUT-OFF SWITCH. TOO MANY TO LIST. TRY THE RELAY AND LET ME KNOW. HOPE THIS HELPS. BEST OF LUCK. THANKS FOR USING FIX-YA AND HONEST RATING IN ADVANCE.

there is problem that I have seen many times with dodges , and I know because I personally own one , the blend door inside of the A/C case ,broke ,bloking the cool air flowing in to the car and allowing just the hat air going though...I have seen that happen before in many other dodges...not 100% sure , but if you mechanic says that the pressure ais OK so the problem have to be inside the A/C case

HI. Here is a complete check list that will help you trouble shot thsi issue. You will find the problem in one or more of these areas stated below.
1. Check Drive Belts - The air conditioner utilizes a drive belt that supplies power to rotate the compressor, which is basically a refrigerant pump. If the belt fails the compressor has nothing to drive it, inspect and replace as needed to restore operation. If belt is intact proceed to the next step.
2. Check for Compressor Clutch Engagement - Turn the air conditioner to the "on" position and set controls to the coldest setting. Start the engine and allow to idle. Then open the hood and inspect the clutch at the front of the compressor, is it turning? "Engaged" if so, the system has enough refrigerant to activate. If the system is low on refrigerant it will not work properly. In this case an air conditioner recharge kit is needed to recharge the system. If the system is low on refrigerant it could cycle on and off, making a ticking noise. If the compressor clutch is not turning proceed to next step.
3. Inspect for Refrigerant Leaks - If the system has a large leak and no refrigerant remains it will not activate. First test system for a static pressure charge, with the engine off attach an ac gauge to the low side pressure port and check the state of charge. Depending on outside temperature there should be between 50 psi and 80 psi. (Cool and warm). A refrigerant leak detector is needed to inspect for leak, but if you do not have a leak detector there is an alternative method. The air conditioner system is designed to run with oil suspended in the refrigerant to lubricate the system. Check for oily residue outside the system by inspecting all hoses, compressor, condenser, evaporator or receiver drier and replace any component that has failed.
4. Inspect Fuses - Check under dash panel and under hood power distribution center. Replace failed fuses as needed, recheck system. If the new fuse fails when reinstalled a short circuit is present and requires diagnosing with a wiring schematic, follow circuits to locate short, repair as needed and recheck system.
5. Check Temperature Control Vents - The vents inside your car are controlled by a cable, electrical servo or vacuum servo. If the temperature blend door is not functioning properly it will cause warm air from the heater to exit the vents. To check this start the car and allow the engine idle, next turn the blower motor speed on low, switch the temperature control from warm to cold while your ear is close to the vents. You should hear the door move inside the heater box as it swings from open to close. If not, insect for a vacuum leak or a shorted motor in the servo, repair the leak or replace the servo motor.

there are few things you need to check out:
1. if the compressor is overcharged it will shut down and you won't get any cool air
2. the thermostat for your cooling system is bad
3. the link to adjust the temperature is too short (did you feel the switch loose when changing temperature from hot to cold)?
hope this helps.

Is the compressor kicking on? If not and the pressure is in the normal range then I would say that the low pressure switch is stuck. It is located on the canister right beside of where you hook up the freon. Unplug it and cross out the plug and see if it starts then.
