I have lost the 'positive click' action on the indicator cancel button. The switch still cancels the indicators, but it is now very sensitive. Can the switch be opened up for repairs or is it time for a new one ? (I have posted a wanted ad just in case). Could this have happened when the front brake master cylinder was recently replaced by my dealer? Any advice would be great, thanks. Its on a 1150gs with abs/heated grips, 2002 model.
