clutch wouldnt engage, now it has.  Doesnt
disengage and cab only blowing hot air

cab not opening???

Check the actuator motor, it controls heat to cool.

I checked all 3 door actuators earlier this week. No wears, damage inside or out...


No leaks found either...


Low now reads 10/ High reads 135- 140

Remember the hotter the temperature, the higher the pressure should be. If it's 90° outside, the high side should be over 250psi minimum. 100° ...290psi


From what i can tell, without dismantling, sounding like evaporator core and/or expansion valve is blocked or clogged. What do u think. The only other thing not checked is the doors them selve for faults or breakage....

I think you're right. especially since line gets cold. It either has an expansion valve or an accumulator and orifice. I don't know which Dodge has.

There is an orifice tube filter in the high side line. Do not know were on that vehicle but there is a disconnect some were in the line that takes a special tool to take line apart. Once line is disconnected you will need a pair of needle nose pliers to remove filter from inside of line.
