Thinking either the compressor/clutch or a switch somewhere. Two shops have given up since I won't pay them 300 to diagnose.
How big of a job is it replace this thing?
I think a new one is $75 or so from the dealer. Don't buy a used one as it's probably dried out too.

The compressor clutch was worn out.
It seems when the clutch coil gets hot it does not have enough power to grab the clutch plate if the plate is worn. The plate gets worn from excessive cycling due to a low refrigerent charge or from many years of normal use.
My mechanic also showed me that there are shims on the clutch plate shaft that are used to set the gap between the plate and the clutch magnets. If the plate is not badly worn you can remove a shim or two and get the correct gap. If the gap is correct it will work and your problem is solved. Unfortunatly I don't know the correct gap but you can experiment by removing 1 shim at a time and see if it works.
This solved my problem but if the clutch plate is badly worn it will have to be replaced. Unfortunatly Dodge only sells the clutch as a unit with the compressor($300-500). If this is too expensive for you try to get a used compressor from a wrecker or try to get the clutch assembly seperatly.
Good Luck
For what it's worth, 4 years ago we had the same problem and paid $900 to have the evaporator coil replaced. I suspect that if I had figured this out before then, I would still have that $900.

Drivers ac ok passenger not so good, have replaced all blend doors. Someone please respond
i see everyone is looking at the blend doors. Dose anyone think that it could be the Ambient Air Temperature Sensor ? The blower seams to be working fine. The A/C had done this in the past I thought that the evaporator was freezing up we would shut down the sys for 5min and the sys would work for an hour or two then repeat this happened when the truck was new then this started happening I think that it is the T-Stat. Is there a T-Stat for both sides?If anyone has another idea PLEASE HELP :sick:

Any help would be great.

If it is a gasoline motor add coolant into the radiator cap opening with the engine running and heater on at idle, give it some time as it takes a while for the air bubble to work its way thru the engine and into the radiator. Then just follow the same as above filling until it isnt bubbling anymore. Take your time it isnt easy to get out the air bubbles. Adding coolant to the tank does nothing to help if your coolant has dropped below the thermostat.

Checked system refrigerant charge and it is Normal at 43 pounds.
About 1 hour later while driving AC cooling output gets warm and stays there. I also noticed when the AC air gets warm the dual climate control gets hot to the touch on the up right face of module.
Could the climate control module be the problem?
I checked all the fuses when AC gets warm and all are SAT.
All HVAC doors work blowing air in all switch positions.
Any one seen this problem? If so please advise. Thanks'
