Default Clown car troubles!

Recently, my 89 Sammy is acting up funny. I shift to 5th gear, and the windshield wipers turn on uncontrollably! Shifting out of 5th stops it. Using the regular wiper controls operates the wipers fine.

Not only that, but the horn also stopped working, and instead decides to activate the windshield wipers! What a joke!

I pull out the windshield wiper fuse, and that stops any of the funny business from happening. The wipers stop working. Does that mean the wiring problem is after the fusebox? What other diagnostic things can I do?

The fact that you ask this question indicates a lack of experience with things electrical - maybe it's time to call in a professional.

Pretty much all of the wiring is "after the fusebox", so yes, it does mean that, but the real reason the wiper's stop when you pull the wiper fuse is that power to the wipers is supplied by that fuse, so when you remove the fuse there is no power to them and they will stop.

If you consider the battery as the source of all power, the power flow is from the battery via the fusible link (which acts as the main fuse) to the fuse box, and from there to the ignition switch (for ignition controlled accessories) and then back to the fuse box for distribution.

There is a "fifth gear" switch on the transmission, and I believe both that and the horn switch provide a ground to their respective circuits, you're most likely going to have to visually look for a damaged portion of the harness.

Please forgive my ignorance.

I was hoping that pulling the fuse would show whether the short/wire decay occurred in the harnesses in the engine compartment or if it was in the dash. I guess it doesn't work that way.

You are right in that the horn does provide a ground, and probably the 5th gear switch. That's helpful! I should be tracing the wiper ground to see where it is shorting perhaps?

I would suspect that the ground point for the horn and fifth gear switch has failed and they are now trying to ground via the wiper circuit. Lost grounds/earths can cause all kinds of stupid things. I would try running an extra ground of the black wire from the horn and see if this stops the problem. If so then find the faulty ground point or just leave your new wire on.
Rather large pic but it needs to be

Looks like it may ground via the washer motor then the intermittent relay. I could be completely wrong though .

Interesting theory! I will have to try it out! Will keep posted.

Default Problem fixed! Not completely sure why...

So, after prodding around alot, we found that the horn solenoid ground and the 5th gear switch ground contact was bad. The screw that held those two grounds onto the firewall was just loose enough so that the grounds didn't register. Tightening that screw stopped the phantom windshield wiper action and restored horn functionality!

Looking through the wiring diagram, I'm still not sure WHY the ground failure would cause the windshield action...

Awww, rats.

I guess that's the end of the clown car & all the funny business.

Well, congratulations are in order and good job tracking it down.

I always loved when all those guys started piling out of the car and running around it.
