We have a SLT and the a/c not getting or staying cold is on my list (9 items long) of things the dealer is checking out this week. I do find that the recirc button helps it stay a bit colder...but then who needs a/c here in washington anyway right? Rainy and gray is this week's forecast - typical June here.
Took mine in to the dealer to check a/c. They told me it was the expansion valve. they replaced it, then the system would not hold the full charge of freon. So the dealer contacted Chrysler and they told them to change the condensor. Will let your guys know what happens.
Here's my 2 cents, I thought I'd check my a/c temp after reading this thread. Best it would do was 50deg with outside air at 90. I tweaked the freon level some and got it down to 42. Normally an a/c should cool about 20 to 25 deg below outside air. OEM states 1.12 lbs. I put in about 1.25lbs. Any auto will cool less at idle since the a/c compressor is turning slower thus moving less refrigerant. Watching the a/c gauges optimum pressure is around 900 rpm's when not moving. Oh and yes on recirc mode it will cool better since your recooling the inside air. Granted a/c theory says your removing the heat from the air not cooling it. Ok well there's my thoughts
