Where does the fresh air come in for the AC/Heat? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1985 K10 regular cab short bed truck. My cab fills up with exhaust fumes every time I drive the truck. It seems to get worse as I'm stopped at a light. I just put a new exhaust system on the truck thinking that would help the fumes and smell but it didn't. Now I'm wondering what else could be going on.

Where does the fresh air come in for the AC/Heat? I'm going to start there and try to trace the path to see if anything jumps out at me.
