my left blinkers come on at random. My bike is a 04 ultra with 30000 miles.I checked all the wiring inside the handlebars,changed bulbs.Where is the module located that turns off blinkers.Any other suggestions would be appreciated. thank you Gilly

 

moisture or water in the handlebar controls... a good cleaning followed by a silicone lubricant / waterproofer should do the trick.

 

It may be a bad switch. I had the same problem with my 05, it would come on randomly. Eventually it it stayed on all the time and wouldn't turn off. It's a bitch only making left turns...HAhahahaha....Anyway, I replaced the left turn switch and the problem went away.
