If the freon is topped off to the correct level check the pressure switch if the compressor clutch isn't engaging. Also check for power to the compressor clutch.

Not sure what the pictures are supposed to show, but is the radio aftermarket?

if it is not blowing at all like the blower motor is out try playing with your ignition switch. wiggle it back and forth and see if the air comes on. their was a recall on some of the half tons for this issue because the switch goes bad due to dc useing a small diamater wire for the switch. the recall replaces the ignition switch and comes with a two wire harness that plugs in to the big pin connector, the small pin connector for the ign switch, and the blower motor if my memory serves me.
