My daughter has a 1999 model Fiesta 1.25 Zetec, it seems the electrical relay that operates the indicators (amongst other things) has stopped working. This happened only last month and was replaced with a new relay, but now its bust again. Is this a common fault with these cars? is there anything I can do to prevent it happening again? She came home this evening in floods of tears after driving 15 miles with no indicators. Any advice welcome. Thanks.
