Find a Part By:

Searching for your parts in the DENSO part catalog is easy. Simply select the type of part you are looking for along with the year/make/model of your U.S. or Canadian vehicle. For vehicles in Latin America, please go here.


        Search for cross reference part numbers for other manufacturers of the parts you're looking for.

        Cross Reference information is provided as a guide only. Please refer to the "Applications" lookup tabs for more detail. Materials and designs will differ among brands, so plugs are not exactly alike. Always check with your OE service manual for proper installation and settings.

        CONDITION: Field reports indicate the vehicle air conditioning system uses only outside air, even if the recirculation mode is engaged or the recirculation mode doesn’t operate at all.

        CAUSE: It is most likely that the vehicle cabin air filter was replaced with the air blend door in the ‘Fresh Mode’ or the blower assembly door was moved manually, damaging the door shaft or the servo motor located on the blower assembly.

        CORRECTION: To prevent possible damage to the vehicle A/C system, verify the air blend door is set to ‘Recirculation Mode’ prior to servicing the vehicle cabin air filter. The proper procedures are listed in both the vehicle service or owner’s manual.
