Delay wipers

I am more than a little curious at this point.

I hope we’re still talking about wiper motors, right? 😛

I got to try the S10 motor today. It almost fits, but the centerline of the motor is shifted to the drivers side about an inch.

On the upside, the crank arm is the same length and compatible with the wiper linkage. I think the Bonneville motor will work well, but I haven't picked up one yet.

I also haven't found the 84-up positive grounding wiper schematics for a G-Body yet, but my Haynes manual is buried in a box somewhere so I may have to go on a garage treasure hunt soon.

That looks promising. So, aside from being off center a bit, it bolts on identically and the linkage arm is the same length. That's cool. Let us know how it works once wired up. Good work! Thanks for your research. 👍

Just try not to let the smoke out.

I'm not so worried about burning up a motor, but I am terrified of burning up that expensive *ss delay switch.

I posted the positive ground system schematics years ago. Now I can't find them. Let me search.

This it?

What all involved in swapping to DELAY wipers? 81 ElCamino

Drove home today in light rain. Sucks not having delay. Is it a switch and wiper motor to swap to a delay set up or is it a bit more involved? May want to swap it over on my 78 Olds Salon too

I dug out my G-Body Haynes manual and found these schematics that show the differences side by side.

Luckily these are for a 2 wire armature motor that my Pontiac is equipped with. There is also a 3 wire variant that is out there, but I am not sure how much different they are.

Yup that's them. I found them too but you guys beat me to it.

Those the bottom one looks correct for 85 up. It's unfortunate that none of the schematics show the range of resistances the delay circuit is looking for.

It looks like later schematics fill in the blank, but it will be a bit of guesswork on what values the switch put out in Low position.

Here are the Bonneville schematics that I will be comparing with. Everything looks pretty straightforward, but see what you guys think.
