Hi just asking around . I live in seattle now for a month, I was driving to work when I heard a pop snd saw smoke coming from my engine. . I pulled over and popped the hood and no smoke so I looker closer at the windshield and a saw a quarter sized crack with smoke coming from it I turned off the car and let it cool then turned it back on with the defrost off and no smoke or heat was there when I got to work. . Any ideas?
