Just found this site and it is great.
Was driving to northern Montana in January to go ice fishing and could not stand the heat in the truck on the drivers side. The problem was the passinger was freezing. Took it in to the local dealrship and they fixed it as they said that they know that there is a problem with the sealer used around the core and they had some new stuff to try to fix it
