Has anyone found a way to put a wiper delay on the rear wiper? This time of year brings some rain with it here in Washington and a delayed wiper would be handy. I don't know if and when such a thing would've been added to the Runners and how difficult it would be to swap into a 1st gen. Would it just be a switch and relay or would the whole system need to be replaced?

Why a delay? What's wrong with standard cycling? I don't find the standard cycling too fast on Southern California rain. I would not find it too fast for Washington rain, either

Yeah, I know it seems a bit OCD. Honestly I'm impressed someone from Southern Cal knew they had wipers. Even in the rain forest that is Washington I don't use my rear wiper very often I do end up using it. I'm thinking about putting a 12v timer into the system. I don't need a typical delay, every 3-5 seconds. I would rather every 1-2 minutes. I'm going to look into perhaps a digital timer that would allow me to cycle in minute increments. I might have to get creative if it requires constant power to remember the settings. I would probably have to allow it to work continuously and use the switch to connect the path to the motor. Again glad to know you are aware that part exists 😁

LOL! Yeah, I replaced this rear wiper arm piece last year .

Yeah, I'd worked with something similar to this. There must be a variety with adjustable intermittent contacts.

Something like this? It would require some wiring into your existing wiring.

I'm looking into this

It seems it would give me more options on the delay.

The only problem I can see is... Is it going to return the wiper arm to the park position or leave it somewhere in the middle of the window?

Gargoyle_Runner

Good point, hadn't thought about that. If the cycle of the stroke back and forth is say two seconds than I could set the timer to power the motor for two seconds every sixty seconds. I sent the seller a question regarding what I'm hoping to accomplish so we'll see what they say.

But if the stroke isn't timed proper than it would leave it in a bad spot for lowering the window. And I don't know if I can bypass it on the fly.

If I recall correctly, the return to park circuit is in the wiper motor, so one of the wires are always hot. You'll need to find a schematic and verify this.
