My left hand side switchgear has completely stopped working suddenly. All buttons, cruise, lights, esc, horn etc along with the thumb wheel no longer work. Ive taken the lower cover off and sprayed contact cleaner in but no joy. Anybody experience anything similar. I think it may be a wiring issues as all buttons failed simultaneously and not one button at a time. Anybody have a guide on how to dismantle the unit?? Strangely the heated grip on that side works perfectly
