It is unlikely that the problem is a fuse, as all of the dash lights will normally run through a one or two fuses, ie they will all go out, not just one. The problem will be a single bulb or LED which illuminates that area of the display. It can be quite awkward to change the offending buld/LED. It is usualy necessary to strip down the dash to some degree and airbags etc may need to be disconnected, and possibly the steering wheel removed, it all depends on make, model, year etc. Unfortunately you may have to take the car to a garage
