Dumb Question

[Seke69]

I only say dumb because I did something about a week ago, and now I can't do it again...WTF?

I need to take the gauge cluster off, to put the one I pulled out the junkyard, in. I JUST took one off, not even a week ago.... on to the question.
the wiper knob comes off with a kind of tensioning screw, how does the light knob come off? I tried a pliers around the shaft to hold it while I gave the knob a turn, but that didn't feel 'right'... I seem to remember the triangular rod being threaded... ugh. help. it's the only knob I have left, because I dropped the one from the junkyard in the mud (along with a million other knobs, screws, and fancy chrome stuff), the junkyard one came off a little too easily if I remember (maybe it was broken?). I don't want to mess this one up.

thanks in advance...

On the light switch itself there is button that you push and it releases the knob with the rod intact. You must reach for the light switch in the back of the guage cluster.

Thank You! it's a good thing I didn't try 'unscrewing' it anymore than a half turn! the junkyard one must've been broken... thanks again.

He does explain the headlight switch removal on this page.
