  Q: How to service and repair the evaporator core on Lincoln Blackwood?

  A: Before removing the evaporator core you need to perform a leak test whenever leaks are suspected. New suction accumulator installation is required only when contamination comes from a failed A/C compressor or when suction accumulator damage occurs. The first step requires the recovery of all refrigerant followed by removing the instrument panel. The service requires removal of the splash shield from the junction box followed by disconnecting wires ends then taking out the junction block bracket by unclipping the electrical connector followed by screw removal and pin-detaching procedures. Match the hose clamps to the Heater Core inlet and outlet before using suitable tools to pull the heater hoses towards the core to release them with crimped clips. Start by disconnecting the spring lock couplings of the evaporator from both inlet and outlet then eliminate the screw and right-hand demister adapter during the procedure. Detach the defroster duct along with the left-hand demister adapter through screw removal. Unfasten the nuts and cut loose the vacuum lines attached to the parking brake release solenoid and panel/floor vacuum control motor. You must detach the heater core and evaporator core housing after unfastening multiple screws then pull out the 15 screws from the housing cover to extract the evaporator core. The installation process requires reversing the removal steps while cleaning and lubricating heater hoses with coolant hose lubricant or plain water if needed and lubricating the refrigerant system with the correct amount of clean PAG oil or equivalent. Additionally, new O-ring seals must be lubricated with clean PAG oil or equivalent. The refrigerant system needs evacuation followed by leak testing which leads to system charging.
