new member here, I have a 2009 RAM Laramie with an AC issue ,AC properly serviced ac works great in recirc mode, heat plenum works, great airflow, good sweating on compressor line, when I change it to fresh air, very little cooling, good airflow, compressor line stops sweating, all zones/heat plenum works, any ideas of what is going on ?

Might check for blend door actuators. There are two behind radio and one that is accessed thru glove compartment. These three are relatively easy to change. Two that are on top of HVAC that are hard to change. Several videos on utube about check and changing the actuators. This has been a continuous problem with my 2009. Change all 5 about 2 years ago. I need to change some again before Winter.

Mine has the automatic temperature control, I think it has only one heat door actuator, which I can see operate when I change the temp. I am going to change the expansion valve next , hopefully that is it.
