Mystery Wipe, Has this been figured out ? Options

[jim_hoyland]

I have an intermittant relay installed. I continue to get mystery wipes when makiing a sharp turn--not always, just occasionally. These mystery wipes seem to always occur when the windshield has just enough grime to really mess up the view.

OK: Could I be grounding the wiper switch when turning the wheel, or does the intermittant relay just go bonkers and give free wipes at its descetion ? (IMG:style_emoticons/default/confused24.gif)

Who's figured this out ?

Your problem is a loose ground connection. This connection is through the steering housing and not a brown wire. There are 4 screws that hold the turn signal / wiper switch in place. This is where the ground comes from. I had one steering column where the boss that the screw screws into was a little low. This means when you tighten the screw, the contact point on the back of switch doesn't fully make contact with the housing. I believe it is the top right screw that is important. Try placing a small brass washer on the underside of the switch where the screw goes through.
