I've got a 90 YJ with the straight 6 cylinder engine and Factory hardtop. It has a rear wiper and washer. The switch on the dash is a two position switch which operates the washer and the wiper both. I need to replace it and have searched exhaustively but cannot find one. Does anyone know where I might find one other than going to a junkyard?

The size of the hole the switch fit's in is the ARB type. I don't know the electronic lingo on looking them up but i think you would need an off/on/momentary switch with the ARB mounting hole. I would guess someone makes them and I'm trying to look it up but I'm not getting very far. Maybe if you sent an email to these people they could tell you how to narrow it down https://www.digikey.com/en/products/filter/rocker-switches/195

I run ARB style switches in my jeep they seem well made despite being made in chyna

I could be wrong but this one looks like it could work https://www.oreillyauto.com/detail/...-amp-6-terminal-rocker-switch/5832611/2622603

It's a off/on/mom switch that's the ARB style but the button on it is for head lights. Most of these ARB style switches you can replace the cover on to anything you want it to have and they do make a wiper switch cover, i would think it would snap right onto that switch but then again you never know until you try it.

Even than i don't know if the factory wiring harness would plug into it directly. you may have to modify the harness.

That is exactly what I was thinking. Everything I see USED on Ebay is around $99. New switch would be under $20. OP could de-pin the factory harness plug, and wire to the switch. I agree that would be the best option.
