Just recently when I turn on my defroster, air blows out of the front vents instead of the top vents. When I switch to the front vents the air blows out good and when I switch to the floor vents, they also blow good. It's just the top defroster vents that won't blow now.

It sounds like the mode actuator has stopped working correctly. Here is the location of the actuator so you can change it out. You might have to try to reset the HVAC system by following this guide:
