    Hey everyone I have a 2010 kenworth w900
    I recently changed my a/c compressor and a/c lines. I filled the truck with Freon and started the truck turned on the ac. The front ac vents blow cold but the sleeper bunk ac blowing warm. Has anyone had this issue before since tomorrow is Saturday planning on finding the issue. What should I be looking for.

    Make sure the hot water is turned off. Or the expansion valve is bad in the bunk hvac unit.
