Thanks Rondo, extremely helpful. Here were my symptoms related to this MFS. The right signal, brake light indicater, blinkers didn't work (the bulb would not light up). I replaced the flasher relay (suspected that would not solve my problem but it was $20) and that didn't fix.
To diagnose, I plugged in the whole light assembly into the left and all bulbs and functions worked as they should. So that left me with wiring from the assembly back to the MFS as the root cause. I wiggled the wires on the MFS unit itself and occasionally the switch reacted as it should but it was intermittent. I looked for a loose wire as others have described but couldn't find anything. I just popped in a new OEM MFS, for $100 well worth it. It works like a charm.
Why OEM? With the number of functions this thing has, I didn't want to take a chance with an inferior part. Hope this helps someone.
