On my 98 tour model I have a minor turn signal issue. Seems like some times the right or left side signallisght just goes dark and will not blink, but sometimes after a time it will start to blink. What is the problem? the activator seems a little tough or sticky.
You need to take the switch housing apart, disassemble the switch, and clean and grease everything. My Interstate was doing the same thing in cold weather last year and, after cleaning everything up (it was digustingly dirty), it works like new again. It's an easy, straightforward job, just make sure you don't loose any of the little pieces.
