The air is cold while moving but gets warm at red light after stopping maybe within a minute. It will turm cold when I start moving. I charged it anyway but did not help. There is a small fan on the driver side beside the radiator that I think may not be working
A?C air blows hot while sitting still but very cold while moving on 2004 Dodge Ram 1500

The fan should run while the compressor on the a/c system runs.If the fan is opperating properly then you may need to check the a/c high and low side head pressures.

i have an 05 that had the same problem. the small fan is the condenser fan and you will hear it if it is working. i am not a mech and i had no problem replacing. the part wasnt too expensive (you just need to buy the motor). you will need a way to pull the system down to pull the condenser. also advise having something to put over the a/c line once they're open to keep debris out of the system while you work. i used pieces of tape.
