SOURCE: expansion valve location
raven 1g: Your car doesn't use an expansion valve. It uses a fixed orifice tube which is located in the smaller of the two A/C lines, just before they enter the cabin area of the car.
Just disconnect the line and pull the orifice tube out of the line. Be careful not to break off anything and leave it in the line.

try adding freon with a dye in it, sounds you have a leak,pay special attention to the a/c lines that run under the truck. notorious for having pin hole leaks,check these and get back to me we'll go from there. hope this helps get back to me Thanks Ray

I am in the process of doing the same procedure on my 2001 durango 5.9... condensor, compressor, accumulator, followed by both front and rear expansion valves. I pulled the rear passenger side trim off after following the pipes to the back. It looks like the expansion vale is the first component hooked to the pipes just as they come through the body into the cabin. It appears to be wrapped in a black sticky mat... I did not unwrap yet so it may not be... What are your failure symptoms? I have a slow leak and a blockage inside the system to where it cannot be fully charged without releasing pressure from the rear of the compressor. I sure hope its not in the evaporator core...
