Hi all new here.. I have a 06 limited and have been having a ac problem for some while now.. Around town both front and rear ac work and blow cold air just fine. While on the hwy 20-30 miles on road outside temp 90+,ac starts to fade, on high you can barely feel it coming out of the vents but it's still loud... Evaporator is freezing up..after a hour plus of hwy driving the rear will slowly fade away also..I can turn off the ac off and around 5 minutes turn it back on and the ac will work good for around 15 or so minutes before fading away again. Had the ac checked out,no leaks,not low on freon. Suggested the front expansion valve be changed..tried that and still same problem..temp monitored from the vent gets as low as 28-30 degree F before fading away?? Any suggestion greatly appreciated..
Thanks Nathan
