Hi. been trying to read up on all threads regarding this job,but have not been able to find anything in relation to any further complications involved if your corrado has Diavia air con! does anyone know of any? also if the matrix has gone and has been by-passed, does that mean the aircon will not work? (obviously it did before the matrix went.) sorry i'm probably sounding a bit dense now,and theres an obvious reason why it doesn't work now. Thanks for any advice on this ,as I will be attemting it in the next couple of weeks. Cheers. Purplebaghera.
