    As in the earlier post, there were lots and lots of leaves, dust, etc inside the evapo of this NSX.


    Quite normal for our NSX as there is no pollen filter at the entrance of the blower motor fan.



    In fact, there is nothing at all to prevent the debris from entering the fan so almost everything will be directed to the surface of the evapo.

    So, started removing lots of parts to prepare for the compression check before start of the service.


    I’m also going to replace all cooling system hoses and cleaning the A/C evaporator so doing several things in parallel.


    The battery is also going to be replaced with a new one and having the blower motor fan out of the way will make the replacement of the coolant hoses much easier so started working under the bonnet.

    After testing the damaged circuit, listed up the sections that required extra parts to be used to re-create the dissolved track and pads.


    Two jumper wires, two hard wires and four soldering bridges were decided to be used for the repair.
