High Beam Flashers = Broken
High beams work then pushed forward past the detent for constant on. But they don't work when pulled back for "flashing."
I assume (statistically) that the the combination "knob" (whatever you call it, with blinkers, wipers, etc) is faulty, commonly. But I figured it's possible that I have a fuse that's burnt (and not visually; we're talking HAIRLINE). I haven't checked or changed them... Is it possible for the highbeams to not flash (only constant on) because of a bad fuse?

I've never had trouble with the headlight circuit, but I expect that there is a relay that is energized by the stalk switch. I can't imagine that all the headlight current goes through that switch.
If you have a wiring diagram, you can verify this. Good luck, |

Hey Larry, thanks for the start...
Now, how do I determine if it's the combination stalk or the ext. lamp relay? THX

Highbeams
David the most common failure we see in the combi switch is the optical horn feature.
The same fuse is used on high or flash. MF |

Wow there Nelly!
Thanks a bunch for the tip Mike. But I don't understand. Could you please reiterate your previous post? Thanks again. What is the optical horn feature in the combination switch!?
