I am new to this forum and I hope someone can help me with this problem. As you can see, I have a 2001 Durango 5.9 R/T.It hasabout 60,000 miles on it. All worked fine last summer. Over the winter the compressor started cycling on and off continuosly. In the summer I added freon which stopped thecycling issue, however the frontonly would blow luke warm air. The rear unit is fine and blows ice cold. I had the system evacuated and recharged, but it did not help with the problem. I am at a loss. Thevents seems to be working, since when I turn the controls to hot, the heat works just fine. Thanks in advance for any help you can offer!

 

could be a blend door, could be the front evap, could be debris that got past the cabin airfilter

 

H valve or w/e it's called.
