My wiper motor continued running after switch was turned off. I had to unplug power to it to get it to stop. According to the Tempest shop manual the problem is most likely the park switch.

So I drilled out the 8 rivets that hold the wiper assembly together. After separating the 2 halves I could see the park switch on bottom side of terminal board and it had a piece broke off. I attempted a repair by soldering a small piece of flattened copper wire to replace broken piece. I didn't trust my repair as a long term solution.

I spotted an NOS Delco wiper terminal board on Ebay and bought it so I could do a proper repair. It came with screws and nuts to mount it. I had to solder the motor wires to the new terminal board. I had rivets to reassemble the 2 halves back together. My rivets have a flat head as opposed to oval but nobody will see the bottom.

I was able to use the 2 gears that I have but I did see NOS gears available on Ebay.
