I'm in the snow storm in Ocean City, MD and my drivers wiper stopped working. The ice was preventing full movement earlier but I thought I cleared it all off. The drivers moves about a quarter up and then stops. Its also loose..I can move it up and down freely by hand. I need to drive 3.75 hours home tomorrow and it'll be slush hitting my windshield. Any quick fix or repair I can make? I have no tools unfortunately with me..probably an autozone nearby. Thoughts?
