So here's what's going on...The combination switch in my 88 is shot. I have rebuilt it once and it lasted a while but now I fear it may be beyond repair. The 4runner has intermittent wipers and the p/n on the switch is 84310-35240. The truck has tilt wheel and does not have cruise control.

I have tried unsuccessfully to find a new one. I know there are used switches available on ebay but I feel like that is a crap shoot.

I pulled the original combination switch out and put in a new switch that only has "mist, off, low, and high" wiper functions. (p/n 84310-35180)(aftermarket but seems like good quality) I figured what the hell, I will try this and see if it works since I cannot find a replacement for my original switch. I have read where some people say the wires are too short for this switch to work with a tilt column but I did not have an issue. I was able to gain a little slack in the wiring harness to make up the difference.

The headlights, signals, hazards, all work. The wipers work BUT, If I turn it to "mist" it blows the fuse immediately. So I do not use that function at all. Low and High will work for a while but ultimately ends up blowing the fuse.

I do not drive my 4runner in the rain unless it is unexpected. But I would like to pick some brains here if there is something I can do to make this new switch work without blowing the fuse or if someone has a line on a replacement for my original switch.

I have searched and I must say I am more confused now than when I started searching. I realize this is backwards from how most guys do it. The normal is to go from standard wipers to intermittent. I honestly do not care. I drive this 4 runner only in warm weather and just want the wipers to work for morning fog or unexpected rain.

I've got a couple of those combo switches, but I don't think any are for intermittent wipers.

Forgive any ignorance, but what about the hundreds of replacement wiper controllers on ebay? From what I am seeing they have intermittent, slow, and fast functionality.

I was looking at one to replace the faded controls on my stock wiper controller, but have more pressing issues to resolve first.

I don't know what's available on ebay, it's mostly BS.n

Hey hey, hey hey hey. Don't be poo-poo'ing eBay. I done seen hundreds of intermittent wipers for us to partake in.

And honestly, I'm batting 1.000 on eBay for gen1 parts.

I know you first posted this over a year ago but did you ever figure this one out?
We must have found the same parts vendor. When I use "mist" it pops the fuse with my new combination switch.

We may never know, he hasn't been here since Sept 2023.

Since the fuse blows on 'mist' and eventually on other settings, it might be a wiring issue or a mismatch in the new switch's compatibility with the original system; checking the wiring diagram and ensuring proper grounding or using a relay might resolve it.

Turning my 4Runner off the other day I bumped the wiper arm "up" to the mist position. Oddly enough, it worked. Also oddly enough, all positions are working and not blowing the fuse now.


Thank you Wiring Issue Fairies for coming in fixing this while I slept.

I'm guessing its a mismatch. This was the horn ring assembly and both controls (lights and wipers) for a really low price. I wouldn't have gotten it, but its the only new one I could find.

Parts for '88 Toyotas are getting rare.

That happens a lot.

The Toyota gremlins create a problem, and later the Toyota fairies magically fix it.

Gotta love it 👍
