Got a 98 s10, noticed coolant smell in cab this morning. Windshield fogged up after sitting at work a couple hours. I think the heater core is toast. Anybody got any experience with this repair? Looks like the whole dash has to come out, and I'm thinking this would be a good job for someone else. I would like opinions on said repair before i spend the $$$$. Its a shame it costs so much to replace a $60 part.
