H3 Crazy Wipers

You might be able to swap the wiper relays out with other relays inside the box. If so, just make sure not to swap out a relay that is required for the vehicle to run. That saves you from having to purchase a relay when it is not needed.

I have a box full of relays and fuses at home and I know there are a few 0202's in there.

I cleaned out an auto parts store that was having a going out of business sale about a year ago... You wouldn't believe the stuff I have.

I've had it happen a few times over the years. I'm going to go with the Multi-Function switch (Fords are notorious for this). It is definitly between the switch and the BCM (or internal to the BCM) as the wipers are returning to the off position. Since it seems like you can replicate this, when it has an eppisode, flip the turn signal on and see if it still does it. The turn signal turns off after a min or two so you won't look like a dork for that long.

It's been a while since I had the collum apart on the H3, but on most vehicles the switches are prety easy to swap out.

I'll give that a try next since replacing the relays didn't fix my problem.

If you do the switch, make sure
to put the front wheels in straight ahead position
pull the sir fuse
lock steering column in place (you do not want to have the column spin and remove the index to the sir coil)
mark location of steering wheel to steering column
to pull the SIR fuse and keep the steering column aligned with where the wheel is prior to removing.

This happened to me the other day and then as I pass a semi on the interstate the running lights I have on top flew out the carrier and starting to beat the crap out of my roof. I'm convinced the H3 is haunted.

Unusual coincidence, today morning was the first time my 3 does this. Rear wiper spazzed, and only once

Mine had the ghost wipe periodically though it has been awhile so I haven’t messed with it. No sunroof and no wet bcm. What I found in researching the issue is the circuit that controls the intermittent part is a board on the side of the motor/gear box of the wiper motor. If you remove the black cover you will likely find corrosion on part of the circuit. Once cleaned the issue should be resolved. That circuit portion is replaceable as well and you don’t have to replace the whole motor.

I saw saw a write up on one of the forums but can’t remember which one.
