Hope somebody can help here, I have 456 with potentially 2 faulty window / central locking controller's and would very much like to borrow or buy a replacement in order to confirm a it's controller or wiring problem.
Eurospares will have a replacement control box, it wont be cheap though!!! You need to be more specific as to the fault, it may just need the windows drop re-setting or a low battery. Ferrarichat has lots of info on windows etc. for 456.
