Outside air pooring in passenger side under dash

Hello all,

I have a 94 CCW and outside air comes in from under the dash on pass side. Why and what can I do to fix it?

Thank you in advance, Paul

Did you check for rust holes? Is it cold, hot, clean, gassy? Did you have a cohort look for the entry point while you are driving? Does it come in while driving only, or while you are parked? Did you check for cracks in the ducting? Is your heater fan missing?

I think it has something to do with the fresh air door being stuck halfway open. No rust holes, happens while driving, it's cold when it's cold out and hot when it's hot out, clean air not gassy. Are you serious about the fan missing?

You would not believe what some people say, and what is actually the issue. I have seen things that are far more bizzare than the heater fan missing.

Used to wrench, so I would believe it.
