The indictors (which work off the indicator/wiper switch) have just stopped working. The switch still works the wipers, full headlight beam etc BUT will not 'click' in the indictors. Also the Hazard warning lights will not flash. ANY SUGGESTION please - I don't think it's a fuse (as having looked the fuse is for the brake lights too - which work). Could it be a loose wire/earth OR is a new conmtrol stick needed... Thanks
