At the end, 8 hard wires, 7 jumper wires and 10s of soldering bridges were used to repair the board.
Initial bench testing went fine so applied conformal coating.
The moment of truth.
Several scenario testing including the Function & Operation checks using my eye, hand, head, face and leg to watch and feel the actual air flow.
Mode 3 testing.
The owner sent the display module together with the CCU board as he didn’t feel comfortable separating the display from the board.
While checking the illumination control, found that both light bulbs were dead.
So, replaced them with the new ones.
The original ones were already blackened inside the bulb and the socket was already turned into burnt brown.
Now, the back lights work fine.
Passed all of the testing and happy with the result.
Final test report and sent out the package yesterday so hope it’s with the owner today.
With the amount of service work, days, etc, this board became the 2nd place for the worst board that I have ever dealt with.
As mentioned like 100s times on here, please have your CCU board serviced before it starts showing any sign of issues. It saves the time and cost for both of us.
Thank you for using my service and hope you will enjoy your A/C in NSX again.
Now back to servicing another NSX.
I need to replace my A/C evaporator and the compressor in the near future before the spring arrives….
