2012 Wiper+Wash goes on by itself - Toyota Yaris Forums

lopat08865 · 03-10-2016, 06:56 PM

Cancelled my diagnostic tom'w w/dealer. Back to CTScott's original plan to replace stalk 1st, then wiper motor if stalk replacement fails to fix [it didn't].

Figuring even w/rain, I can pull washer fuse & still drive w/wiper function. Saw no crimped wiring in engine compartment & way too much to tear-out-to-track-down the wire's full run.

Still thinking it's washer-switch electrical problem since BOTH go on intermittently.

But saw something here saying that switch inside motor fails to show ground at "park" [or bottom] position, so wipers keep moving until it finds it. So let's try that?

Still appreciate any advice on this thread. I will keep it open until solved.

Opened another thread looking for pdf/imagery/video/or just plain advice on how to get at the wiper motor in a 2012 Yaris H/B.
