i just picked this up the other day , its in transient accross the mighty Pacific Ocean as we speak

it simply looks Stunning , or maybe it the first time a seller used golf coarse as a Prop ?

Mat, If you have a spare 84652-60330, I'm trying to find one. I like my modified ford intermittent wipers but am thinking of using one of those switches with a 85940-89101 wiper relay. I will have to modify my motor to switch on the hot side.
 
I've been looking at this 85940-89101 module. There has been some work on this that can be found in the 60 section and other places. I think it can be easily modified to be used with the negative switched wiper motors. This is the module and schematics.

I think connecting the NO contact of the module relay to ground instead of +12v, and adding a relay or transistor switch between terminal 2 and the capacitor to change the polarity of the park switch should make this work fine. Also the 43k resistor can be replaced with a fixed and variable resistor to change the timing.

I used this to inform my intermittent wiper mod. good stuff.
 
Does the mud brain trust have any thoughts on this option?

 
Might peruse this thread if you haven’t already…

 
Would it be just so easy to change the switch to this type model?

Edit: There is said ”negative ground only”, so because the original switch just ground the motor (not feed power to it), I think there is relays needed between the yellow, blue and white wires.

That looks awesome. Wish that was around when I was building mine.
 
I want to explore running a stepper motor using an Arduino as a controller. Then you could program the end points, the speed, the delay, everything you could want.

The trick is going to be making the mounting plate, keeping everything small enough to fit under the cover, and a switch with the right combination of positions to handle it all plus the washer fluid.

It looks like MaTTi's switch would accomplish that
 
The switching on the ground side of the motor is a problem. I've used relays and mosfets to reverse the polarity, neither is an elegant solution. This works pretty well:

So, if the new switch would only control relays (which would ground the wiper motor), it would work? Or are some mosfets needed too?
