For some reason that I can't figure out, my MIST, INT, and II settings on my windsheild wipers don't work, leaving me with only the I setting. Any ideas as to why the other settings don't work and how I can fix it? Thanks!

Pull the switch and take it to an electronics shop to be inspected and repaired. The contacts inside the switch may have worn down, something may have had a melt-down or it may be the old RX-7 standard of shitty soldering. You'll have the switch back quickly and cheaply, as opposed to forking out hundreds for an OEM one...

From what I understand, this is simply a relay that has gone bad. Take a look at this website. Might help you some.

Good luck.

thanks, I'll check that relay tomorrow.

Bad relay in the wiper switch, replace relay #3.

What about if your wipers won't turn off? Is that a relay problem as well?
(currently if I plug in my windsheild wiper motor it will just keep going and going and going and the switch does nothing)

Icemark

Either the relay is stuck on or the switch is jammed

Icemark

Amur's answer here is wrong. The relay failure is common. The switch contacts almost never wear down.

The relay contacts get dirty and the relay fails.

the wiper problem is very common! i've had to replace mine and so has a friend of mine. check your local junkyards.......i got mine for $15

I was thinking of the contacts in the headlight switch, and assumed that the components in the wiper switch would be similar. The contacts in my 1st headlight switch did wear down. Found out the hard way while delivering pizza one night. The contacts could not, according to the fellow who inspected the switch, be replaced. I got a used switch to replace it.

Icemark

If the contacts in the switch went, you would get one setting malfuctioning or all the settings malfunctioning. You would not get 2 or three settings malfunctioning.

BTW zelgadiss-san, you may wish to also search next time, as this problem is common and has been covered quite a few times.

I'd do the new relay swap in lieu of one out of a wrecking yard. I went thru at least two out of a wreck yard before getting smart enough to just replace the relay.

And ICEMARK, what are you doing with a rear wiper relay in yours. Don't you have a convertible????? humor.

Go to this thread https://www.rx7club.com/forum/showth...threadid=35372 for part numbers and other vital information. Icemark and Asherwood seem to be the key people on wipers. I've fixed two and made a royal mess out of my third spare one(way toooo much heat and sloppy soldering). There is a guy on http://www.fc3s.org who will repair them. Icemark has made the same offer before.

The electronics in FCs are Own3d !

Or the penultimate thread, try this one with good part numbers and prices: https://www.rx7club.com/forum/showth...threadid=48605

Icemark

Not an actual picture of mine... and mine I cut the extra opening straight across.

Icemark

Yeah, I am all out of cores right now, but I can repair one sent to me for about $20 + shipping back to you.

HAILERS

That is more than just a good deal on the twenty bucks and shipping. Where was this guy when I needed him!

MaxRX7

that's what I'm thinking

NixxoN

How do I fix either of these problem?
I took apart my switch and I don't have a Relay #3 that is in that photograph, I don't even have a relay 1... just a 2... damn GX :P
I can turn the switch just fine, and the part the switch is connected to is turning as well so i dunno...

NZConvertible

Icemark, I have the same symptoms; no mist, intermittent or high speed, plus they won’t park on their own. I replaced that relay as per the TeamFC3S write-up but it made zero difference. Convertible wiper switches are as rare as rocking horse droppings over here, so I need to repair it. Any ideas?

Icemark

Are you sure you don't have relay number three? It may be hidden behind the plastic, if the switch has not been repaired in the past.

Coupes without the rear wiper and 'verts will not have relay number 1.

If you can see the circuit board and the relay is really not there, that would be your problem, although I would be curious on how the wipers worked even in the low position.

Icemark

Let me dig up my schematics in the morning and see what else you might look for

NixxoN

So how exactly do I take the plastic off? just break it... or....

NixxoN

n/m I figured it out.. I went with the flathead screwdriver heated on a stove technique :P
