Hi! My 2005 GMC Yukon Denali XL (6. 0L V8) has been having issues with the turn signal activating the hazard lights. It used to be only when I used the right turn signal, the hazards would come on, but now it randomly happens with both. It'll do it for maybe 15 minutes or maybe up to 3 days. I read on Edmunds. com that someone with the same issue replaced the multifunction switch and it didn't go away. I think this GM TSB might have an answer, but am not sure: gm technical service bulletins number 01946 Any ideas? I hate to mess with the multifunction switch (expensive) if that won't fix it. Thanks!
