There is a little gate that is controlled by a motor that allows the flow of air, it's pretty basic, getting to it however is not. It means disassembly of the dash, that's plastic and brittle from 2 decades of sun and heat.

Or maybe that gate is for the heater core? it's been 10 years since I did anything like this on a car.

Your vents are vacuum controlled. If moving the control doesnt flip the gates, you probably have a vacuum leak somewhere.

Has it started to idle shitty or anything like that?

Also, reminder to replace that fucking coolant. Those 2.2ls last forever, as long as you keep the coolant clean. Especially with a 94-97, had finicky heads that liked to blow gaskets.

Alrighty if I have a vaccum leak, where should I look for it. How can I find where the leak is. It does make a racket, like metal clanging together, but I believe that to be due to the fact that when I got it the oil was low and might've damaged it slightly. However, The racket does get louder when I turn the a/c on.

And thanks for the reminder, I do need to get on that. What kind of coolant did these take? I don't have the owners manual anymore.

Thanks /diy/ ! I found the problem. it was a vaccum leak. 2 hoses had popped out of connection. one connected to the vaccum reservoir and the other attatched to the hood close to the window. reconnected them. will probably need to get something to bind them there better,

Thanks for the help!

use small zip ties on the ends like hose clamps, should stop them from popping off
