I've been told from the beginning that the 2003 Dodge Durango 4.7 a/c has never performed well. Brought it to the dealer/mech with little improvement in a/c. Works a little at 70 to 80 temp range but a total failure at higher temps. Has anyone had luck improving efficiency or corrected the problem

 

What are your pressures doing?

 

Hill ding at 100 for both low and high ports. Would indicate compressor issue. Clutch engages. Darn turns on but goes off shortly afterwards which seams to indicate a relay/swictch issue.
