• Q: How to Service and Repair the A/C Expansion Valve for the Auxiliary Climate Control System on 2003 Ford Windstar?

  A: Start the process of expansion valve service and repair for the auxiliary climate control system by taking out the A/C evaporator core. Start by cutting the insulator tape and unclipping the additional piece before disassembling the fittings while using wrenches for each fitting to protect them from damage. The service begins by taking out the thermal expansion valve from its place in the core. The installation process starts by fitting the new A/C evaporator expansion valve together with green O-ring seals which need lubrication using PAG Compressor Oil YN-12-C for Ford specification WSH-M1C231-B. It is important to note that the green O-ring seals remain hidden within the connections. You should now attach the refrigerant tubing which includes the A/C liquid jumper line and the A/C suction jumper line. The A/C evaporator core must be reinstalled after you apply ESA-M99G50-A insulator tape to the bulb and clip. The system must be checked for proper operation during the last step.
