2010 Yaris Windshield wiper malfunction - Toyota Yaris Forums

WalterWhite61 · 07-13-2019, 04:56 PM

Wipers work only at fast speed and when turned off do not park. I read everywhere that this means its the switch. Installed a used switch and wipers did the same. Thinking that maybe the used switch had the same problem, installed a brand new switch - still the same !

Anyone ever run into this issue ?

I've been trying to get a schematic without buying a whole book. Does anyone have something they can share ?

I don't think the car computer has anything to do with circuit
I guess the wiper motor could be at fault but doesn't seem as likely for this type of problem.

Any help would be appreciated.

Wipers don’t park. Does this mean they stop moving when you turn off the switch?

In my 2007 service manual. The wiper motor has two speed inputs. One for Fast and the other one for Slow. It also has a park switch in it. So it could be the motor assembly or the wiring harness that powers the motor.

it happens few times to me while wipers operate at full speed regardless the stalk input. Unplug and plug again the negative battery terminal solve my problem
