The air con is not working on my focus. I have tested the wires and there is no live going to the pump. Does anyone have a wiring diagram so i can trace the wiring or any advice.

Thanks

had this on my climate ..theres a safety built into the circuit ..if the pressure drops then the relays wont activate ..mine was because the rad had a pin hole in it (thanks for the cr8p rad ford) local rad place said he gets more fords in because their ally is poor quality ..fiestas focus mondeo etc ..the diagnostic check was free but the rad and regas cost me £165 all in with a lifetime re-gas and a service on the pump

best call out a mobile expert to test the system as said it camn be a pressure switch it could be a wire it could be many things its far cheaper to have a pro diagnose rather than replace parts in the hope it fixes it

Can you not get a Haynes manual, They are worth their weight in gold for the home DIY'er.

haynes can show you but without the specialist equipment you wont get far i use the pros they will find the issue easily
