i cant get the heating blower inside on my temperature control, blowing the air towards me, just on window or to the floor, is there one more button?
its a 92 super charged

From 92 to 94 General Motors did not give you ability to change where the air is directed. The system will choose where it wants to put the air for you.

However..if you look at the firewall of your car next to the window wiper motor, there is a black container. This is the vacuum canister for your heating system controls. check the hose going to the bottom of it for cracks or being disconnected.
