Avalon Hybrid Wiper Failure

I had the same issue on my Avalon. Check the wiring harness near the wiper motor. It's a common spot for corrosion. Does it affect your turn signals as well?

Turn signals are fine. Which connector exactly near the motor? Any tips on getting to it without breaking anything?

Okay, good on the turn signals. It was a faulty plug for me. If I was you, I would get it checked at a workshop.

Appreciate the input! Turns out it was the plug, just like you said. 95€ later and it's fixed.
