Possessed Windshield Wipers

So...I'm driving down the road the other morning and my windshield wipers decided to just start going by there selves. I messed with the switch and nothing. The only way to turn them off was to pull the fuse and kill all power to them. Any ideas what could be causing this? Only thing I can think of is a short inside the switch on the column.

 

I think you nailed it. How's ye ole warranty lookin'?

 

I would check the relay.... easy to do... just swap it for another one and if they don't turn on you found it.

 

Do you have rain sensing wipers? I was driving a Ford Expedition Eddie Bauer Edition, and the wipers just started freaking out on me. I found out later that it has rain sensing wipers, and it reacts even to just road dirt/water being spit up by the vehicle in front.

 

No, no tacos do....

 

Your floor mats got in the way and they will need to trim your wiper switch.

 

Sounds more like the "Park" tab broke in the wiper gearbox. It's the peice that tells the relay when the wipers are at the "bottom" of the stroke.....

Chevys are famous for it and you could get a new electrical portion for the gearbox for about $20..... Don't know about the Tacomas.
