94 gmc sierra stepside pick up, how do I find and fix this interior problem. happens using ac or heater, assuming hoses going to blower and or cooling unit, it is inside nasty coating of antifreeze? ac freon?
Coolant will be orange or green in color
Freon evaporates although if an AC leak a slick oil can appear
