Temp 78 degrees 55% humidity- driving to Detroit from Mackinac area. Air conditioning on low temp---fan on hi---about 1/2 way home after 1-1/2 hrs from Waters Mi last food stop, air temp from outlets in dash became just cool ---was cold for entire trip and since new (7/14) -125k miles--We stopped rest area, turned off engine-I checked under hood--no noises with engine on-----after 15 minute walk break- air conditioner returned to "cold" again and stayed cold all way home. . I took refrigeration classes and this one stumps me, although I am a novice. Frozen evaporator? Then thawed out while off for 15 min? This has an auto temp control as well as rear evap but was on "low" not 68 or 70 degrees. Thinking that low setting should have took computer out of equation and temp probe in cabin (as far as ***** being modulated thru evap)......low to me means wide open and ***** wide open on all time correct? Wonder any tsb ever on this with 134a. ..ps ...lifetime Mopar warranty...125k on front brakes still good. Motown
