On my Chevy blazer.
It looks like it's all vacuum actuated. I believe it may be the AC/ heater control switch. Even with the dial turned to off, a bit of air still comes in at the feet when the vehicle is cruising at highway speeds. I just need to take the trim on the dash out so I can get to it. The lines are small so checking it may be difficult.
Rock Auto has the part for $140 shipped. Anyone have any cheaper alternatives? There's always junkyards, but how do I know the one I pull isn't faulty either?
