2011 2.3 auto, just picked this truck up, runs and drives good. AC works great when driving around town, nice and cold, but when you hit the highway and get over 50 plus, it quits cooling. It blows but not cooling. Let it sit for a bit and back cooling but get it up to speed and same issue. Any info or ideas? Thanks
 
Low refrigerant charge?
 
It shouldn't be, but any possibility you're hitting the WOT cutoff too soon?
