Yeah I get that, it’s hard to explain what I’m trying to say but it feels like when max a/c is on and going highway speeds, I guess the wind pushes past the open recirculating door. So that means the blower isn’t pushing all the air through the vents and making excessive wind noise. I’m not entirely sure if that’s the issue, just my thought on it. I know that you’re going to hear the blower running, but I don’t think it’s normal to hear the wind outside from behind the glove box. Maybe it’s jusr bad design, but any other car or truck I’ve driven never had that much wind noise from that areaS What gets me is that at some points when driving at those speeds is that the wind will suddenly stop, like something is closing back up again, yet I can still hear the blower as normal. It’s a really bizarre problem.

The heat is just that the core was leaking so I disconnected it for the meanwhile. So on colder days my girlfriend would just turn off the vents on her side, but she still feels the air coming through them. (I’ve gotta have air blowing through so I usually keep the ac on, despite her pleas). For the manual, individual vents there’s a door in there that opens and closes to block the air. Being that this blazer 18 years old, I guess there was some sort of rubber flap or something on the black door (the one that is right before the vent controlled by the dial underneath it) that deteriorated. It looked like there was glue on it so I’m guessing that it had something attached. I just wanted to know if anyone else noticed it and what kind of material is supposed to be on it?
