Default '70 GP Wiper Switch?

Replaced the motor and pump, but no workie. Is the switch something that I can rebuild? How do I remove it?

Thanks! Bill

before relacing parts do some testing,

is power getting to the switch

if so is power leaving the switch when you put the switch to the appropriate setting

btw, GP dashpads had fiberglass rather than steel so grounds at the switch can be a common issue

Default Grounds behind the dash panel, 1970 GP

Factory grounds were overlapping thin pieces of steel.

When the car gets old 2 things can happen to these grounds. One is that the metal starts to rust &/or corrode. And the other is the plastic mounts that hold threads which in turn hold the screws which hold the metal strips tight up against one another can crack or break off the back of the dash pad carrier.

Some times the threads in the plastic get weak, that or the threads are stripped out from over-tightening. The wiper switch uses one of it's "mounting tabs" that one of the ground strap end overlaps. That one plastic mount right beside the wiper switch in the dash pad has to be in good shape so that the ground is nice and tight.

Default Grounds

All phases of the wiper work off of grounds it just switches the ground at the motor for high low and wash power should be constant !
