2004 Chevrolet Silverado vent control

No matter what position I set my vent control knob to, air only comes out of the dash vents. Will not direct air to the defrost, floor or any other combination. What can I do to fix the problem? Thanks!

    My girlfriend has the same issue, and I am sure that it has to do with the actual knob adjustment ... it seems to be stripped out. I have looked a little bit for a replacement knob but no luck thus far.

There is an actuator located at the bottom of the dash .. just remove it and turn that little shaft with a pair of pliers gently one direction or the other and see if that's the problem if so replace that actuator,, ((((((( be shure to unplug the actuator before starting the truck )))) and disconnect your battery when u install the new actuator .... so the climate control can relearn its position for accurate door travel...

2004 chevrolet silverado ac is not blowing through dash vents only through defrost vents


these trucks are equipped with an electric vent door motor known as a vent actuator. I believe the actuator that controls this vent is located behind the dash on the driver side.

AIr always comes out of the dash vents no matter where the controls are set.


Sounds like a vacuum motor problem which controls the blend door and its position inside the dash board area where the flapper directs air from the heater core to the defrost vents or the vents, or the floor, as directed by climate controllers on the dash. Good luck on this repair.

2004 chevy k2500 no air out of defrost vents, temp controls work fine cannot direct air to defrost vent


You may have a problem or bad connection in the a/c-heat control unit I'd remove that and inspect that first. As long as you do have heat elsewhere you can rule out the blend door actuator. There are vents that open and close and you will need to be able to access and check them. You will need to remove dash to be able to get to them.

The AC air comes out defrost sometimes and comes


what position is the control switch in? does this occur when accelerating?

the door that directs air flow is controled by a vacuum motor. the default position for the door directs air flow to the defrost vents in the event of vacuum loss to ensure the windsheild will be clear of mist. if there is a small leak, vacuum will temporarily be removed when accellerating and the motor will revert to the default position. there are vacuum lines from the control knob to the motor you must check these lines for leaks. the diaphram in the motor may be bad. also check the main vacuum supply line to the control knob. usually red in color. if there is a vacuum storage cannister. it may be leaking. this cannister will maintain vacuum for the circuit when accellerating. engine vacuum decreases when accellerating.

No air flow through the rear vents with ac or heat on high


make sure the control knob on the dash is on "RR". This lets the driver control all the vents in the back. The heat only comes out of the floor vents, if you have the knob on the blue dots that represents the air conditioning in which the cool air will come out of the vents up above in the back. There is also an area on the control knob on the dash where you can turn the knob to shut the heat and air conditioning off. If the knob is in this position then you can control everything with the knob up above the seat right behind the driver's seat.

Dash Vents wont blow as selected


THE COMPRESSOR IS SUPOST TO RUN NOT MATTER IF IS IN HOT OR IN COLD MODE SOME TIME THERE IS A POSITION WHERE THE A/C WILL BE OFF AND THIS IS ON THE KNOB CONTROL WHERE YOU SET DEFROST AR FT VENTS
ALSO ON THE THE SWITCHING FROM DASH TO FLOOR CHECK FOR ANY VACIUM LEAKS FROM THE ENGINE COMPARMENT SINCE MOST OF TIMES THIS IS CONTROLED BY VACIUM ACTUATORS
