    Don't hurt me.. I've been thru the search and I know this is common. I have checked the drain tube #3 and it's not blocked.

    Picture of the lines under the cab, just above my fuel tanks going into the bunk area on the driver's side.

    #1 is my AC line and it's ambient temperature. Not hot, not cold to touch.

    #2 - is very hot.
    I've seen people say there may be a valve. Others said they installed a ball valve. I am unable to locate any such valve.

    Can someone provide a picture and location of the valve, please.

    Note: I added 1 can of refrigerant, it didn't do anything. I'm open to suggestions.

    Thank you.

    #2 is not a ac line. Its hot because coolant is flowing inside. Thats a heater line.:rolleyes:
