2009 Honda S2000 BaseSECTION Blower/Evaporator Unit Component 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 (SP-10) (see A/C REFRIGERANT OIL REPLACEMENT ).
  • 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 (E) 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 (see RECIRCULATION CONTROL MOTOR CIRCUIT TROUBLESHOOTING ).
  • Make sure no air is leaking from the upper housing (F) the lower housing (G).
