Do you have any idea what you're doing? Can you tell the liquid line from the suction line? The expansion valve will be at the end of the liquid line just before the evaporator. There should a sensor bulb connected to the outlet of the evaporator connected to the expansion valve. After you've replaced all these pieces, be sure to evacuate the system with a good vacuum pump before putting any refrigerant back into the system. Failure to do that will cause an early failure of the system - pulling a vacuum is not an optional step. Every MH a/c system I've ever seen has a sightglass in the liquid line. Recharge the refrigerant till the bubbles/foam passing the glass clears up and stop there.
