I have a 1500 Ram,5.9 auto, 2000 , 75,000 miles
The AC is not cold at all. The AC line that goes into dash (aluminum line) is very cold, zero deg or less. The Low side presure is around 40 psi, don't have gauge to check high side. Compressor cycles 3 or 4 times a minute.
Clamping off heater hose makes no difference. Cruise Control works (seen that posted here as a symptom of a vacuum leak.)
All heater functions work and temp is changeable on heat side.
Is this a problem with the Heater /AC controls?
Thanks
Gary D.
