Have a weird issue which seems to have just started with my Focus. Whenever I engage the rear windscreen wiper, there is this weird clicking sound coming from around the fusebox area/centre console. When the wiper moves across the rear screen, you hear this "click click". Now before you ask its not the usual sound the wiper makes as it moves across the screen, but a distinctive clicking sound which wasn't there before.
Anyone come across this before or have any idea what it might be. Was thinking of changing the fuse should there be one for the wipers.
