    As expected, DM10 and 11 had to be removed in order to check the
    nearby tracks and clean the area.

    These old components have to be carefully removed without breaking them

    They are not RoHs compliant.

    While carrying out the Eng Refresh, another owner sent in his A/C CCU board
    for preventative maintenance.

    He wanted to clean his cabin temperature sensor due to lots of dust
    trapped at the aspirator fan (and possibly making annoying noise) and

    he thought it would be a good idea to have the CCU serviced while
    the centre console was off.

    As in my previous blog A/C CCU Board service A-01 and A-02,
    the previous service caused more damage than repairing the board.

    I already knew that it will cost a lot if I repair this board so I checked

    Before going out for the test driving session, wanted to finish
    the A/C CCU board service.

    As reported earlier here (Eng Refresh 02), I found that
    the R & L condenser fans and the A/C compressor switched themselves on
    even when the CCU was in Off position.

    Addition to the CCU, the Fan Control Unit could be faulty but first thing first.
