I have a 1.6 Fiat Brava R reg 1998. The Fan heater, the cigarette lighter and the window wipers have stopped working. The fuses all look good and Fiat have told me that while they cannot exclude the Relay as the source of the problem, these rarely need replacing. They have suggested that it may be a wiring problem. I have also had a mechanic replace all the valves, just prior to this problem occuring. Could he have accidently cause a loose connection somewhere?
