Didn't check coolant level of freezing in -30C weather, truck overheated in winter, probably freeing up the heater core and putting tiny hole in it. Truck smelled like anti-freeze whenever heat was turned on. A definite clue, with no cure but to replace the heater core! I think GM must have hanged the heater core from a wire on the assembly line, the built the truck from there out!!
I've had my Blazer for 3 years now and have been fairly happy. This summer, my windows started fogging up. It's worse in the winter! I try to defrost my windows and it gets foggier and smells like fish! Foggy vapor comes out of the vents. I drive with my windows cracked and the vents covered just to see. I have a four year old and one on the way. I can't wait to get a new car. I'm looking into Nissan.
