SC WIndshield wiper switch recommendations
I have this non parking issue with the wipers. I know how to solve it. Problem is it returns every 6 months or so because of the plastic parts in the switch being jelly plastic.
I am quite willing to invest in a new switch -even though they cost gold- but I see they are still the same ***** design. I am guessing this is just URO new old stock from 1975. What did you do? Suggestions?

Those switches were OEM from SWF or Valeo, IIRC. Who I believe still make/supply them today. When I bought my car ~20 years ago, it had 230,000 miles on the tub. The headlight/indicator stalk felt kind of "soft" and sloppy - although it seemed to operate OK. After a few months, it began to flip the headlight lights to high beam whenever the indicators (flashers) cancelled. At first just now and then - then, quite quickly, every. single. time. Seemed as though the resistance to flipping to the "high beams" position just wasn't there any more. I dropped the switch and peered at it. Seemed clear that the reason the action was mushy was because plastic detents provided the "switching" action, and that nothing I could easily do (given that the mechanism was riveted together and not trivially fixable) was going to improve that. So I replaced the switch with one ordered from our host. Something less than 30 minutes after fitting it and noting the stiff, crisp, positive action of a brand new switch, I marched over to a computer and ordered a matching one for the washer side. Which similarly improved that... They still operate perfectly 50,000 miles later. Had to settle for SC-style legends on the stalks rather than the period-correct middie ones. But the car is a driver, so no biggie. My $0.02? Column stalk switches are wear items. Replace them when they're worn out and you'll be a lot happier.

thanks for looking . I have seen some non OEM switchess at 911 design, but they also seem to copy the plastic nipple thingie that causes the problem.
I am wondering if the OEM parts are newly manufactured or NOS. If it is NOS the plastic has degraded even before I put hem in. It is very expensive for a part where they did not bother to solve the problem at the base....

The wipers don't park on my '74. I put in a new SWF wiper switch that did not solve the problem. The Haynes manual says to check 31b ground on the motor and to clean the cover contacts.
The wiper motor axle has fine splines. How do you put the motor in park position so that you can put the wiper arms in park, then install the motor?

Answering my own question: My non-parking wipers was found to be a green connector that broke free. The motor has connector housing with normal spade connectors on one side. On the other side of the housing are larger terminals with wires that go into the motor. These wires aren't soldered on but kind of spot welded on, but one was just floating in space. I soldered all 5 terminals on and connected the motor w/o installing for testing. I verify that the motor no longer stops the instant that the switch is turned off. It continues to park position. With the motor in park I'll put the wipers in park position and assemble.
