7. Disconnect the connector (A) from the dashboard wire harness. Remove the mounting bolts and the rear heater-A/C unit (B). Plug or cap the lines
immediately after disconnecting them to avoid moisture and dust contamination. Disconnect the connectors (C) from the rear blower motor, the
rear blower resistor (heating/air conditioning), the rear power transistor (climate control system), the rear air mix control motor (climate control
system) and the rear mode control motor, then remove the wire harness clips (D).
8. Install the unit in the reverse order of removal, and note these items:
-
If you're installing a new rear evaporator, add refrigerant oil (DENSO ND-OIL 8).
-
Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the correct
O-rings for HFC-134a (R-134a) to avoid leakage.
-
Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.
-
Do not spill refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.
-
Do not interchange the inlet and outlet heater hoses, and install the hose clamps securely.
-
Refill the cooling system with engine coolant.
-
Make sure that there is no coolant leakage.
-
Charge the system.
