When I first got my car a few weeks ago, my windshield wiper mist feature did work, because I remember accidently turning it on when I was first trying to use the wipers. However, since then it has failed me. The wipers go, but no fluid is released. It is very cold, so I thought maybe it was just frozen (although it is supposed to be good to -30 degrees). However, it was in the 40's the other day and it still didn't work. Is anyone else having this issue?
