Because closing the sunroof before using them is a pain.

These just have a single slit in them, unlike the traditional kind. Is there some trick to adjusting them? Can they be adjusted?

 

They aim pretty low on the windshield stock, but they do put the water out with force. Probably unavoidable to get it to not come in the sunroof. You can try cleaning out the nozzle with a needle.

 

Wow, this is a good point.. I wonder how much of mine goes in my sunroof without me noticing! Haha.

I'd try pinching or kinking the feed hose somehow partially, even though that may be bad for the pump. Cheap fix, right? Otherwise, I'm not sure.

 

Really? There's no way to adjust these?

 

you could put a wiper moter and blade on the roof to clean the sunroof at the same time...


Might get some funny looks though.

 

Have you tried putting a pen or a paperclip in the hole and moving it up and down? Might work even with a slit in them.
