HIGH BEAM/LOW BEAM SWITCH

[Michael Stiles]

The headlights on my 87 R10 are stuck in the high beam position. When I try to switch them with the turn signal lever it will not click...and for some reason I though replacing the turn signal lever itself would fix the issue. I found out this was not it. So what I could use help with is whether it would be the white switch on the lower part of the steering column that needs replacing or is it the switch on the steering column where the turn signal lever hooks in to?

I hope that all made sense and if you can help it would be greatly appreciated. Thanks gents!

IIRC, there should be a rod that the lever pushes when going from high to low beam.
Can you check that it's engaging the switch on the column?

Edit:

Thinking more about it, your turn signal switch/cam may be all in one.
Turn signal and dimmer switch.
Hopefully someone can verify.

You can also connect a new one outside the column to test. If that works then you can install permanently.

Another quick question, is it tilt steering or straight column?

If it is tilt, the knuckle being loose will affect the high/low switch. Did that in my s-10 blazer, had to tear the column down and rebuild the knuckle it was so bad.

Top of Page 43 - not a truck column, but the upper is the same. See the weird looking black piece ? When you pull the wiper switch arm, you are pushing that, which by means of that curved end rod, transmits hat motion to the dimmer switch on the lower LH side of the column.

That switch may be out of adjustment.

Sorry for the delay in response, but the truck does have tilt wheel. When I try to switch from low beam to high beam I do see the switch at the lower end of the steering column move. This being the white switch that I assume the rod goes to. It just doesn't "click" like it usually would when it was in working condition. I may just end up tearing down the column to see if I can see everything and get a better idea of what's going on.

Goldie Driver, thank you for that document. Huge help for getting eyes on what I'm looking for without actually having to tear anything down yet. I will use this to trouble shoot. Thank you again!

That switch can be adjusted - I would try that 1st.

Glad that helped , by the way !
