I have a FORD FOCUS 1.8 Petrol.
Recently noticed a click coming from fuse box/relays under passenger dashboard when switching ignition on.
Also hear a single click when turning dipped headlights on only.
Everything seems to be working apart from this click noise.
Have only noticed this happening since disconnecting battery to fit a new driver's seat.
Could anyone please advise if I need to change relay or if it could be something else.
Any advise would be great.
