I'm not exactly sure what you are saying, but if everything is working, and nothing comes out of the vents, it may be a proportioning valve or vent diverter flap. Does the hot air go out the top vents?

nothing blows out of center vents only floor and top thanks for you help !!!

Chances are it's the diverter flap in the ac/heat duct work that is stuck. It may be as simple as a loose vacuum hose. Do research on-line to see if anyone has posted a YouTube or other how-to. If all else fails get, or borrow, a factory manual.
