04 durango 4.7l dual air new compressor, new expansion valves, new drier, new circulation switch, all lines cleaned. if you put the 1.875 lbs for single unit the compressor cycles with no cold air, if you raise the 134 to 2.50 dual unit the compressor will not cycle.

 

Wrong section. You have a second gen Durango. Regardless, expansion valve systems don't cycle as much as the older "oriface" style. I also don't know what your question is. But again, you need the 2nd gen section.

 

Moved to second gen.
