So I bet you've always wondered what went on inside your vacuum wiper switch, haven't you? Me neither, until I tried to remove the knob while disassembling the steering column (it just pulls off by the way). I tried turning it past it's operating range, thinking maybe it screwed on. Nope, all I did was strip the gear inside. Oops.
So I thought, might as well try to take it apart, I can't make it worse right? The back cover is crimped in place, I used a little 1/8" punch to gently tap those crimps open. A light tap on the shaft and the rear cover popped off, inside is a gear on the shaft, and that gear engages some teeth formed onto the cable which when turned moves said cable to operate the wiper motor valve.
I had stripped the teeth on that little gear where it meshed with the teeth on the cable. I used a punch on the end of the shaft and backed up the gear with a socket so there would be somewhere for the shaft to go as I tapped it out. Inside, a wave washer to keep some tension on the assembly.
I flipped the gear over, reassembled it onto the shaft and meshed it with the cable after pulling the cable into the proper position. Put the rear cover back in place (after giving it all a little shot of light lube, I used LPS 1) and gently tapped the crimps back in place with my punch. Ta da, good as new!
