Today i ran out of washer fluid after that i poured new rainx bug wash. But when i turned the rear washer on it wasn't working & neither the wiper. So i swapped the 15A fuses but nothing worked. After that i rolled down the rear window & back up again AND IT STARTED WORKING.....
Hmmm, that might come in handy. The last few mornings the mirrors have been heavy with dew but not the back window. I wonder if I crack the back window a bit if the mirror/rear defog button will still defog the mirrors? I found on my FJCruiser if you didn't have dew or ice on the rear window then the heating element on the rear window would discolor badly. On the other hand, I could take a few seconds to wipe the dew off the mirrors and not worry about it...
haha, this happened to me too. called the dealer and the tech told bout this trick, sure enough. i must have put my hand on the window switch getting in and moved it down a bit.
After my battery ws replaced the rear washer & wiper did not work. The rear window was fully up but had to be re-initialized by putting half way down, then fully up and holding the up button for an extra few seconds.
