did you check for a leak, because if you are getting icing /condensate on the lines you are either out of refrigerant or you have a leak somewhere, those metal lines should never freeze under any circumstance. refrigerant aka r-134a is just like freon, it's contents are under pressure and if you release that pressure really fast you get moisture in the lines which then freeze up causing icing on those lines

If it had a leak,the dryer would not get cold,we had one with the same problem come in at the shop,was a rat nest in the ducts.

glad you got it fixed.

I had the same problem, I found the linkage wire was disconnected from the cold/hot lever. and it was on hot when it happen. you have to disassemble part of the dash or pull out the control unit and check it. Chancayano

My 2007 ranger does something similar. It feels as if the cold air is fighting the hot air and the hot air wins! The compressor works fine, but when I set my controls to AC the hot air wins, when I select Max AC the cold air wins. Sounds like something is wrong with my middle knob which is the hot/cold temperature setting. Am I right???
