Air Con Issues

[horsemeatscandal]

The air con in is my car is out. It doesn't need a regas, there are no leaks and the compressor is working. I've had an auto electrician look at it and he's stumped and has had to contact Honda for some wiring diagrams or some such. But I've had a thought...

The car originally had a touch screen through which you controlled the air con (apparently manufacturers were doing this st as far back as 2002). Before I picked the car up, the touch screen broke so the dealership swapped the head unit for a standard one. While everything else works on this head unit (stereo controls, fan speed, even displays 'AC ON' and 'AC OFF'), could it be that swapping the head units over has had some effect on the connection between the AC button being pressed and the compressor actually firing up? Or am I clutching at straws?

The car is a JDM import 2002 Honda Accord

Hondas had an issue with the A/C relay, not sure if the Accord was affected by this but it might be worth checking?

Yes, my wife's 2008 Civic aircon stopped working and it just needed a new relay, was about £20 and 2 minutes work.

Totally forgot to update this.

Turned out that if you put a head unit from a diesel in to a petrol, the AC won't work (this was the actual cause, not just a coincidence). Sorted now.
