Just let the dealer fix it…...

 

For anyone else you experience similar issues, I was able to fix it by opening the cover and tightening the nut under it. When I opened it, it was loose enough for me to hand tighten it a bit but it still fell down after turning on the wiper. When I used a wrench to tighten it further, it stayed up and was able to continue the swiping motion.

You can see an example of how to open up the cover at the beginning of this video -

I will post update on how it holds up. I will be on trip and won't be using the car for a month, so it might be 2 months or more before I'm able to post update.

 

One of my kids pulled on the rear wiper arm and now it hangs down. When I put it back into position then turn on the rear wiper, the motor tries to pull it up but fails and it falls back down again. Is there a quick fix for this? Do I need to replace the entire arm? If so is this something I can do myself and where can I get the part? Thank you!

Try this: remove plastic bolt cover; unscrew the bolt and remove it; take off the entire arm by lifting it off the bolt, then put it back on in the opposite direction (in other words, pivot it 180 degrees); put it back on the assembly and put back the bolt. Test it. That worked for me. I just had to adjust arm placement.

 

I meant "nut," not "bolt."
