heater controls

Postby tkelley [OP] » Aug 08 2011, 7:01pm

I just got a 90 silverado, and my heat and ac work fine but only out the front vents,the defrost doesnt work neither does the floor.When i push for the direction for the heat to go to the floor or windshield it just keeps going to the top and then when i hit the button for it to go down it goes all the way without stopping.Anyone know what that could be?
