I would say its in the dash unfortunately you will have to pull it out to inspect.

Hey there. I've got a 96' blazer and this happened to me as well. Turned out that I was getting the 4 wheel drive checked out because it wasn't engaging and they found that a vacuum hose was loose. The mechanic said that when it is a vacuum hose, the blower won't engage correctly to the desired setting... usually just blows out the defrost. Hope that helps.

Your air leak is in the heater control switch. You have to replace this unit. I have done this in both S10 Blazer and S15 GMC. Remove the front dash cover and remove the control bolts. One control is electric and the other is air controled. You can get this unit from GM or take your chance and buy it from the wrecking yard or off EBay.
Now some one also posted that there 4X4 is not working also. This uint is controled by electronic control. The transfer case has a electric motor on it and is control by the switch on the dash only. There is a canister outside under the front right (pass) side fender that controls the locking gear for the front drive axel Chech this for air leaks.
Now for the banging in the heater unit. It is the blower motor. I have the same problem right now in my S15. It needs to be changed.
