Sounds like you may have disconnected the cable that diverts the blower ducts up and down. Sorry but the radio may have to come out again to access it.

AC issues


The problem is either an actuator or the door associated with it. Sometimes the gear strips, especially when the system goes thru a recalibrate after power has been removed and reapplied. Below is a diagram of the locations of the actuators.

2000 Ford Taurus SEL ac/heat blows through floor and defrost vents only


There is no vacuum to the controls. Look for a vacuum hose that is no longer connected to the engine intake manifold and repair it.

Air will not blow out of any vents in my 06 ss trailblazer


If the air only blows from the defrost vents, your problem is a vacuum leak more than likely under the hood either to or from the vacuum tank. The vacuum tank commonly looks like a plastic ball with vacuum lines attached to it. Check for cracked lines, disconnected lines or a cracked vacuum tank.

Air will blow out of floor vents and defrost vents but not air vents


Vacuum hose for air vents is not connected. These black hoses should be accessable by feeling under the dashboard. The hose just slides onto the air vent intake. Hope this helped.

Replaced battery in 2004 chevy trailblazer 4x4 8cl., then air conditioner doesnt blow out the face vents only the defrost and feet. any ideas?


Typically, you have a vacuum issue, air flow system is designed to FAIL in the defrost mode, so no vacuum, doors are spring loaded to blow out defrost ports.

Ac and heat will not blow threw vents just floor and defrost


Sounds like your selector switch is messed up to select where you want the flow of air to go. When you turn the switch to where you want the air to go does it work on floor and when you turn the switch to vent it doesn't?
