The expansion valve is located inside the evaporator box either behind the glove box or inside the mid dash console behind the radio and climate control. It has to be removed to gain access to the valve. Not a job for the weak at heart. Take it to a reputable repair shop or dealer. There should not be a need to replace the expansion valve. If your A/C experiences moments of being clogged, (which is exhibited by warm air blowing from the A/C vents) but then after a while the A/C blows cool again from the vents, you probably need to evacuate the system and pump it down to vacuum out any contaminants and to remove the moisture. Recharge until there are no more bubbles or a foam stream present at the site glass on top of the accumulator. If those were the symptoms, the only other suggestion would be to reverse blast the expansion valve with nitrogen prior to sucking down the system, which should dislodge anything blocking the expansion valve orifice. Just because an expansion valve is partially blocked, doesn't mean it won't still function; moisture in the system is the culprit which turns to ice and completely blocks the opening. After it has been blocked for a while, the ice will melt unclogging the opening and the freon will start to flow again into the evaporator - the system will again function blowing cool air from the vents. Up until the moment moisture contamination makes its way around back to the small orifice to freeze again, blocking the flow of freon to the evaporator.
