Doctor Gollum, Chazza 12 and Kevin Wood ...thank you so much for posting and trying to help me. All of your help is much appreciated by me. Firstly to Doc Gollum, no the previous owners did not remove or change anything. The air con and all was working fine and did so for a few weeks after we bought it. The radio stopped suddenly at the same time as the demisters on front and rear window and air con and fan (yes climate panel dead) but put in code for radio and that is working fine. No the air con is not working. The fuses have been checked and they appear to be working and fine. The whole circuit is dead...and these items are all on the same electrical circuit as far as I understand....the aircon, the demisters and the fans for blowing hot and cold (manually) are all dead and all on same circuit. Have already tried the reset of system as described as it is written in the owners manual but no good. Think I need to have a diagram or info on the wiring so that I can get in there with an electrical tester to see if a wire has burnt out or a relay not working. My electrical tester has given up the ghost but I can purchase a new auto electrical tester but cant do it if I dont have any way of knowing what I am testing. Hope what I have written makes sense to you guys? Thank you so much for all your help, I am in France and doing all this in French too....and the temperatures here are now over 40 degrees....so I desperately need to get this fixed if possible and there is no garage I can turn too (if there was one who agreed they would want me to do that with a blank cheque and they can be a bit untrustworthy so I am loathe to do that but anyway so far no garage has agreed to take on the work and I cannot find an auto electrician except for one who is very far away and is booked up for the next two months....so I have no choice but I must do this myself). Please continue to help me if you can. Does anyone know how I can get a workshop manual for this mode,l Omega reg 2002, 2.2cc diesel manual saloon DTI...? or any way of posting me the electrical circuit? or any relevant bits of the workshop manual or write an explanation of the wiring or anything at all further to help me please? Thank you so much....so glad to have found this forum for Omega owners....
