Wiper Switch

Another challenge!

You could easily count on one hand the number of times this car has been caught in the rain but on one of my last outing, danged if I didn't get rained on.  No big deal really except that the wiper switch on the turn signal stalk quit working and I was unable to turn off the wipers.  (I did so by unplugging the connector under the hood at the wiper motor.)

I have removed the steering column because I already had it loose to address the starter switch replacement, so it was just a few more easy steps to get it out of the car.  I was able to remove the pin that secures the outer shell of the switch and when inspecting, I found a loose, very small ball bearing the appears to set under a spring in the speed selector rocker?  It could have come loose just taking the switch apart.  Nothing looks broken, per se, but something was clearly wrong.

I checked the Tech Manual and couldn't find anything there in terms of a diagram that shows how this is supposed assemble/work.

No doubt some of you have shared this experience.  Any advice?

Thanks,
Harry

My advice: Send it Sead (one of our members who specializes in rebuilding these).

There is some info here:

And it does mention that the small ball bearing can become dislodged causing the issue
