2001 RKC with sidecar...sidecar brake and turn signals on right signal. headlight modulator Some time ago I noticed the left directional would blink 3 times normally and then start going faster than normal. If I am moving it will sometimes cancel the blinker even going straight after about 10 blinks. This does not happen stopped. The malfunction does not happen all the time but quite often No TSM/codes are indicated, and both rear and front directionals are working equally,both left and right. Bulbs are not LED. Don't quite know where to start.
