    So long story short.. AC went out 2 months ago. TA replaced the compressor but wasn't able to replace the dryer as its striped. I got to take off the hoses and replace em. My AC with MAX blows 70... Shouldn't that be closer to 50? What could be causing it to be blowing 70 lol.

    This is a 07 INT 9400i

    I think 55 is about right. Though, if it's taking in 100+ temps from outside . . .

    Hard to say could be many things,low charge,high charge,not pulling a good vacuum.
    Does the condenser get hot?
    How often does the compressor cycle?

    Have you got it set to recirculate or fresh air? That will make a difference.

    Replace the condenser and orifice tube. They're plugged up with crap from the failed compressor. Ive never seen a 9000 series ih that wouldn't blow under 40 degrees when working right.

    What was the reason for replacing compressor?
    If it was just the clutch went bad,the rest is probably ok.

    It was leaking when i bought the truck air was ICE COLD then after 1 month it leaked away to nothing. They said everything else was fine it was just the compressor.
