Ok I have a 2001 Montero Sport that I can't figure out what the heck is going on with the AC system. I took it to 2 dealerships they can't fine anything wrong either, Ok, from the start, My truck only blows cold if it is moving. I had the freon level checked (dealership) it was on point, I had the compressor checked (dealership) they said it was fine (dealership). They check the drier receiver,evaporator, expansion valve, and condenser and fan, all were ok... The dealership was so confused they didn't charge me for the visit....I have no idea whats going on with this truck...does anyone had any idea's...... I don't know if there is an orifice tube in this system, but that would be the only thing that was not changed out,,,,by the way when the 2 dealerships could not find anything, I changed the following; drier receiver,evaporator, expansion valve, and condenser and fan. I'm lost,,,,,HELP
