How to Service and Repair the A/C Expansion Valve in a System on Ford Windstar?

First step in servicing the expansion valve requires you to take out the A/C evaporator core. Split the insulator tape and take off its clip before using wrenches on both fittings to detach the A/C connections without harming their fittings. Once the core is clear take off the thermal expansion valve from its place. To set up the new valve use the new O-ring seals and clean YN-12-C oil with WSH-M1C231-B Ford specifications that you apply on hidden connections. Join together the refrigerant tubes particularly the A/C liquid jumper line and the A/C suction jumper line. Press the bulb and clip into place with ESA-M99G50-A insulator tape before putting back the A/C evaporator core. Perform one last test to confirm system performance works as intended.
