This morning i was in a city street had just left home and turn on the front defogger, after 2-3 min. i noticed some smoke and smelled something burning. then i heard a crackling sound. i looked around and didnt know what was burning. i then turned around to head back home. there was no one else on the road. i then turned off the defogger and noticed the cracking sound was my windshield had cracked from the bottom left side above where the vin # is located. now im afraid that my truck will catch on fire if i turn on the front defogger. so, i wondering if you have received any complaints regarding the defogger.
