Should the windshield wipers park on a 1974?

Chris64 · Dec 28, 2024

I finally got around to adding wiper blades so I could try out the wipers. They seem to work but the speed didn't really change much from slow to fast. Also when I turn them off they just stop wherever I turned them off.

Are they supposed to park? Is there an intermittent?

I'm afraid to even test the fluid squirter :hahano:

They park, and intermittent was not an option until later years.

Successfully fixed my wiper parking position switch

After reading several great threads on here, I took out my wiper park switch and found that the contact was being held open by a small "blob" of plastic on the stationary contact arm: The contact points could never meet. After careful scrapping and digging, out it came and now the points meet...

experiencing a similar problem in my 81 k10. replaced the motor/washer assembly because the original would not "park" the wipers but rather stop them wherever they are when the wipers are switched off. Same problem with the new motor assembly. Is there an external module or contact switch?

It should park. The park switch is in the motor. Your wiper switch could be bad or wiring to the park switch or ground.
The thread linked below contains 2 diagrams:

You can test all functions of the motor with removing the harness and connect 12v and check with the grounds with jumper wires.

Be certain your switch is grounding.
