I have heat but it doesnt blow through my vents, it blows through the floor and through the slots by the window, but not through the vents, anyone has this problem?
I think what you're describing is an underdash vent tube problem. may be deteriorated or have come disconeected somewhere. I take it that you can't change from like heat to dash to defrost either? The panel control may be broken or the vac line under the hood against the firewall on the passenger's side may be bad. Good Luck.
I agree. Check the tubes underneath the dash -- especially if you've been back there for a stereo or something. There should be a canister on each side of the dash (left and right). Check to be sure those are connected to the vacuum line that runs to each of them.
