  Q: How to Replace an Evaporator in an A/C System on Chrysler Pacifica?

  A:

  When replacing the evaporator, begin by taking the HVAC housing out of the vehicle and unloading the tubes holding the Heater Core. Cut the foam seal out of the HVAC housing seal flange around the points for the fresh air inlet and the expansion valve/evaporator tube under the dashboard. Then, take out the expansion valve from the evaporator inlet and outlet tube fittings, interrupt the HVAC wire harness wire between the Blower Motor and the wire harness on the HVAC housing. After removing the four top screws, move the distribution housing away so you can lift out the hooks holding it to the evaporator housing. Loosen the screws that connect the upper intake air housing to the lower and evaporator housings, placing the screw inside the fresh air intake hole. Lift off the upper intake air housing and you will see the air door and blower wheel assembly; after that, remove the screw and washer from above the recirculation door. Remove the evaporator housing's twelve screws along the rim to uncover the upper section and try not to lose the small rubber plug for the HVAC wire harness evaporator temperature sensor at the same time. Remove the evaporator and its insulation altogether and try to leave the clam shell type seal in place along the edges and bottom. If changing the evaporator, insert 60 milliliters of oil into the refrigerant system when you install the refrigerant. Slide the evaporator and foam wrap down into the lower area of the housing so that the seal sits in place. Put the top part of the housing on the bottom, making sure the rubber grommet and wire harness fit in the groove and hold the two together using twelve 2 Nm screws. Cover the evaporator housing with the upper intake air housing, so the recirculation air door pivot is set correctly and fix it with three screws pulled firmly to 2 Nm. Connect the upper intake air housing to the lower intake air housing with two screws that are then tightened to 2 Nm. Ease the distribution housing hooks into the evaporator housing receivers, put the top of the housing in place and attached it with three 2 Nm screws. Connect the HVAC wire harness into the clips, attach the blower motor connector, add a new expansion valve and put a new foam seal on the HVAC housing flange seal. After that, place the heater core tubes and HVAC unit housing back in the vehicle and calibrate the HVAC Control Actuator using your vehicle's procedures.

  Q: How to Properly Service an Evaporator and Adjust the Refrigerant Oil Level on Chrysler Pacifica?

  A:

  Refrigerant oil level must be adjusted by the mechanic before servicing the refrigerant system in order to avoid causing harm or improper function to the A/C compressor. When only replacing the A/C evaporator, put 60 milliliters (2 fluid ounces) of recommended refrigerant oil into the refrigerant system. Whenever a refrigerant line needs work, make sure to replace its O-ring seals and gaskets. The first step is to set the A/C evaporator in the lower housing, while making sure both the drain and insulator are clean and put in place. Wrap the evaporator tubes with the rubber flange seal and secure the top HVAC housing below the bottom housing. Fasten the two halves of the HVAC housing to each other by screwing 13 self-tappers in. Make sure they are tightened to 2 Nm (17 in. lbs.). In the last stage, securely put in the HVAC housing, include the proper amount of refrigerant oil according to the replaced parts and only use the oil suggested for the A/C compressor in the car.
