Blower Unit Component Replacement
Note these items when overhauling the blower unit
Scheme 96
- The recirculation control motor (A), the power transistor (B), the blower motor (C), and the dust and pollen filters (D) can be replaced without removing the blower unit.
- Before reassembly, make sure that the recirculation control linkage and doors move smoothly without binding.
- After reassembly, make sure the recirculation control motor runs smoothly (see «RECIRCULATION CONTROL MOTOR TEST»(/acura/rsx/i-2004-2006/remont/automatic-hvac-system/#climate-control-system) ).
Scheme 97
Scheme 98
Scheme 99
- Recover the refrigerant with a recovery/recycling/charging station (see «REFRIGERANT RECOVERY»(/acura/rsx/i-2004-2006/remont/automatic-hvac-system/#climate-control-system__refrigerant-recovery) ).
- Remove the bolt, then disconnect the suction line (A) and the receiver line (B) from the evaporator core.
- Remove the blower unit (see «BLOWER UNIT REMOVAL AND INSTALLATION»(/acura/rsx/i-2004-2006/remont/automatic-hvac-system/#climate-control-system) ).
- Remove the self-tapping screws and the expansion valve cover.
- Carefully pull out the evaporator core without bending the pipes.
- Install the core in the reverse order of removal, and note these items: If you're installing a new evaporator core, add refrigerant oil (KEIHIN SP-10) (see «A/C SERVICE TIPS AND PRECAUTIONS»(/acura/rsx/i-2004-2006/remont/automatic-hvac-system/#climate-control-system__ac-service-tips-and-precautions) ). 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 the refrigerant oil on the vehicle; it may damage the paint. If the refrigerant oil contacts the paint, wash it off immediately. Make sure that there is no air leakage. Charge the system (see «SYSTEM CHARGING»(/acura/rsx/i-2004-2006/remont/automatic-hvac-system/#climate-control-system__system-charging) ).
