"All of us using R-134A would experience an additional 5 degrees of cooling if we would keep our hot air from being expelled and raising the interior temp of our Benz. "

Sometimes I have a real hard time with other than technical issues. I examined this sentence at least three times trying to figure out whether you were talking about the recirc door or heater control or something.

I think that I finally figured out the source of the hot air. Thanks for the laugh.
