The IPC that was repaired by Cluster Fix did not work. The upper light portion would not turn on when pressing the TEST button.
So, I ordered an IPC from Jim Finn. I unplugged the IPC from Cluster Fix and plugged in the one sent by Jim, and it worked like a charm.
What sort of issues with the climate control? The memory of the ECM does get cleared when the battery is disconnected but I don't know of any direct connection to the HVAC system. Good looking car by the way.
