Fiesta headlights flicker, indicators skip, and wipers change speed on their own.

[Stewart0777]

Having an issue with a ford fiesta style mk6, mostly issues with electrical components of the car, they most often seem to occur after about 20 mins of driving. The Indicators are skipping, the headlights flicker, the wipers change speed on their own, you can hear a clicking noise inside the car, which only happens when the other problems start. Sometimes the abs and handbrake lights flash up together other times the airbag and battery lights flash up but are not on constantly.

Sounds like water/ corrosion in the underbonnet fuse box, a good clean in and under the box should sort it
