Blower Motor: Service and Repair
Components Replacement
Blower/Evaporator Unit Components Replacement
Note these items when overhauling the blower/evaporator unit:
-
The recirculation control motor (A), the power transistor (B), and the blower motor (C) can be replaced without removing the blower/evaporator
unit.
-
If you're installing a new evaporator core (D), add refrigerant oil (KEIHIN SP-10).
-
If necessary, remove the expansion valve (E).
-
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.
-
Reinstall the evaporator temperature sensor (F) in its original location.
-
Before reassembly, make sure that the recirculation control linkage and doors move smoothly.
-
After reassembly, make sure the recirculation control motor runs smoothly.
-
Make sure no air is leaking from the upper housing (G) and the lower housing (H) fitting.
