2005 Mercury Sable Evaporator Parts Questions & Experts Answers

• Q: How is the evaporator core serviced and what steps are involved in its replacement on 2005 Mercury Sable?

  A: The evaporator core service includes the entire core assembly as well as instruments such as internal doors seals and door linkage. The housing replacement process needs the transfer of blower motor with wheel assembly and heater core and cover along with dash panel seals and vacuum actuators. An entirely new suction accumulator is required only after a failed A/C compressor causes contamination or when the suction accumulator itself becomes damaged. The first step to remove the heater core and evaporator core housing requires the removal of the heater-to-dash panel seal together with the air conditioner tubes-to-dash panel seal and the air conditioner evaporator drain tube seal. The process to accomplish removal starts with electric automatic temperature control modules by first unhooking electrical connectors then removing nuts before vacuum harness detachment and lastly undoing two screws. Start by disconnecting the electrical connector of the temperature blend door actuator followed by its screw removal and subsequent shield removal then action. The procedure requires detachment of the A/C evaporator case damper door assist spring and a careful remover of the damper door lever without causing any damage to it. The vacuum harness of manual climate control vehicles should be detached from its mounting bracket. The process begins with cover removal while unscrewing the temperature blend door then twisting the blend door and removing the heater core. Manual climate control vehicles require the removal of both the blower motor along with the blower motor resistor. To replace the blower motor speed control in vehicles with electronic automatic temperature control you must disconnect the vacuum hose and remove three screws before taking out the assembly of blower motor and blower motor speed control. Separate the in-vehicle temperature sensor hose with bracket from the air inlet duct while you disconnect the vacuum hose and remove three screws. The vacuum control motor requires removal by first detaching both vacuum hoses and then disconnecting the screw before lifting and rotating the motor to extract it. Recording the current vacuum system and powering components' positions should be done prior to their removal. The installation process should follow the opposite sequence of removal by first installing the vacuum components and wiring harnesses according to their locations then the vacuum control motor, shield, and air inlet duct followed by the bracket. When installing automatic temperature control vehicles you must put the in-vehicle temperature sensor hose and the blower motor in combination with the blower motor speed control system unit. The installation sequence for manual climate control vehicles demands replacement of both the blower motor and blower motor resistor. The installation of heater core requires you to rotate the temperature blend door while fitting the cover completely. Manual climate control vehicles should have the vacuum harness installed onto their mounting bracket. Proceed to attach the metal link and A/C evaporator case damper door lever while maintaining its shape and then install the A/C evaporator case damper door assist spring and temperature blend door actuator. Complete the vehicle installation by connecting electrical components and vacuum harnesses of the RCC module for electronic automatic temperature control while applying seals for the heater-to-dash panel and air conditioner tubes-to-dash panel and air conditioner evaporator drain tube.
