1996 Chevrolet Corsica heating system

Yes, it seems to sound like the air is blowing like it should. This sound comes from the right side of the dash, of courts that's where the mother is though. Otherwise you don't hear much if you're on the drivers side. Also, yes all the settings work right when you switch them from vent to defrost, etc. It sounds to me like all the air is going somewhere behind the glove compartment. But we're not sure and also aren't so sure about how to get to that area to see. Kind of afraid to start taking the dash apart unless we know what we're doing.

Oops I think I hit the wrong letters or my autocorrect changed them. My reply was supposed to say : of course, that is where the motor is, not mother lol.

OK, my bf thinks the fan may be blowing backward, I'm not sure how it would have got that way. He asked at the parts store about the wiring and was told that reversing the wires won't reverse the fan. The people we got it from had fixed some things on it, maybe the fan was one of them and they put it on backwards? Anyway, he plans to check that. We also have a Corsica with either blown heads or head gaskets so if the fan's bad we can use the one from it. If what he checks doesn't help we'll check for blockage. I'll let you know what we find. We may also need advice on taking the dash apart to do that too if we end up needing to. Thanks.
