I have a 2007 Sonata. It is freezing outside now, and when I first get into my car the wiper fluid comes out just fine, but after my car warms up it does not come out at all. All other discussions I have found apply to the opposite, and no doubt more common, situation of ice buildup in the lines and then thawing when the car warms up. Is there something that could be expanding when the car gets hot and pinching the line? I do not have this problem in the summer.
FYI: I know pretty much nothing about cars.
