Bringing this over here as well, thanks for the help in advance!

 

I have now pulled all the relays I know of, all the ones in the fuse box, and the ones in the 2 small boxes on the driver's side fender. No change, only way to shut them off is the square pink #106 fuse.

I have ruled out the multi-function switch, I took the column apart and took the entire switch out, they STILL stayed on.

So at this point, unless someone knows somewhere else to look for relays, I think I'll have to dig out the motor itself and start checking wiring.

Any other ideas?

 

Sounds like your GEM is starting to go.

 

I doubt its the GEM, there are no other symptoms and no water.

There is some kind of solid state controller that controls the wiper motor, at least that's what i see in the prints, it could be the problem. Just putting it out there.

 

I found a switch inside the motor, which is the park switch (wipers down). This should only have power when the key is on. I suspect you have something going on with the ignition switch, or the custom wiring has put power where it doesn't belong. If it's the rat's nest... I don't have a diagram for that to aid you with.

 

This might help.

 

Ok, so I've been doing research, and as far as I can tell the relays for the wiper motor are built into the motor itself.

So as far as I can tell, looking at wiring diagrams the only option is to replace the motor. I highly doubt it's the GEM or VSM.

Thanks to those who have helped so far!

 

Sorry I cant help but that has to be one of the most annoying things in the world. I obsess over the speed of my wipers in relation to the rate of the rain drops hitting the windshield. Having wipers stuck on when it's not raining might just drive me totally insane.

 

Well, the wiper motor relay is definitely the issue. Took it off, plugged in just the motor, still on.

Tapped it a few times with a small hammer... shut off and worked briefly. 2-3 miles down the road (wipers on due to rain) it got stuck open again.

Oh well, guess I'll have to choke up the dough for a new motor.
