Hey Scotty,
I am experiencing truly "intermittent" wiper behavior with my 2011 Avalon. This car has the "luxury" feature of automatic windshield wiper mode vs the traditional timed intermittent wipers, although they still have a speed adjustment. I assume the adjustment is for the sensitivity of the automatic wipers to engage based on the accumulation of rain on the windshield, but rarely do they work properly. If its light drain or drizzle the wipers often won't do anything, if its raining harder then they usually work better, sometimes even perfectly (speed up/slow down based on changes in rain or speed of the car), but usually I'm just struggling with them.
As a "luxury" car I have found this feature far more frustrating/useless vs traditional intermittent wipers. I'm not sure if there is something wrong with the sensor or these "automatic" wiper features are always problematic...I have to believe they are supposed to work better than this. Unless I can fix this the car only has low/hi wiper speeds....
Thanks in advance,
Warren
Good luck on that one knowing outside of the Toyota dealership could work on that work on that. Even my equipment doesn't access that bizarre of a feature. You'd be paying them whatever $140 an hour to fiddle around personally I'd live without it
But Scotty, I haven't been limited to low/high wiper speeds since my 1977 Toyota Celica...not sure i can go back...
