Going by your original ECU, you have a factory T5 ED?
2DAD is an EB2/ED XR6 Manual ECU and the original:-
3DAC is an ED Manual, LWB. according to my listings.
I suggest you put the old ECU back in to check the aircon works properly. They may be incompatible.
I have been told that the ECU doesn't affect the aircon but there are a number of vaguely documented instances of climate control wiring differences between EB2 and ED, I don't know if the older ECU is contributing to this.
I no longer have an EB2 XR6 T5 ECU to try out in my factory T5 EDs to compare behaviours.
Can you try out the 2DAD in another car to see what happens, maybe an EB2?
Let us know how you got on, will you?



What goes around, comes around.
