2003 Trailblazer Vent Actuator?

Hi- I've been told the vent actuator door is stuck on my 2003 Chevy trailblazer. No AC/Heat from front vent, but floor and defrost ok, as well as back seat vents still working. Apparently a common problem with this make/model. Any fixes? Trying to avoid going to dealer and pay $$ for simple fix. Mechanic wanted $600 to take apart dash, but I remember reading a more simple fix where dash could remain in place???? I'm not able to do work, but looking for some help in Baltimore area. Thx for any info.

THE CAM SHAFT ACTUATOR IS LOCATED IN THE CYLINDER HEAD ON THE FRONT RIGHT HAND SIDE JUST ABOVE THE POWER STEERING PUMP. AFTER YOU REMOVE THE ACTUATOR CHECK TO SEE IF ANY OF THE SCREENS ARE DAMAGED OR MISSING. IF SO REPLACE THE ACTUATOR. ALSO CHECK THE CRANKSHAFT END PLAY. IT SHOULD BE BETWEEN 0.0044" - 0.0153". if excessive crankshaft end play is causing this concern, it will be obviously out of specification by as much as.050" or more when a pry bar is used to move the crankshaft back and forth. IF THIS IS THE CASE AN ENGINE REPLACEMENT IS RECOMMENDED DUE TO THE AMOUNT OF DEBRIS IN THE ENGINE. IF NO EXCESSIVE CRANKSHAFT MOVEMENT NOTICED REPLACE THE CAM ACTUATOR. IT WILL ALSO BE NECESSARY TO DO AN OIL CHANGE.

SOURCE: front fents not working on chevy 2004 trailblazer other vents ok

yes, if you vent is not working when adjusting direction control, the problems is behind the ac control unit, common problems with GM. you going to have to tear into the dash and see what linkage broken or came off, not hard to do on blazer if have some mechanical incline background and some tools, it not hard but time consuming. Or drive behind any dealership and ask any mechanics does he know any one does a side work, you be surprise, many shop have mechanics that does side job, saving you lots of money from shop cost. 35-40 buck to fix with out part.

SOURCE: ignition actuator rack broke from acuator rod

Yes unless the rack has been broken also, most parts stores carry them. Just turn your key and see if it moves or not. The out side shell of a colloum is mainly for looks.

SOURCE: How to put an actuator in a 2002 Trailblazer

Lots of things can be called an actuator. Door lock Mirror adjust, overdrive, and 4 wheel drive to name just some. The door lock is the most common and it's held with one rivet near the bottom of the door and the new actuator will come with a new revit. With the door panel removed and you reached around and made sure that your on the right one drill or chisel out the old revit, pivit arond the actuator to get the wire unpluged, Look at the new one to see how it goes. unhook the lingage on an angle and slip in the new one. Not bad to do if your used to doing stuff with out watching your hands. ( sort of like under the covers at night ) Then you'll get it done fine. The other actuators you need to say whitch one, 4 wheel drive?

I change my radio on a 2004 trailblazer LS an my front face A/C & Heat Vent stop working any idea what might have happen...all the other vents are flowing correctly...


yes it happens more than you know vent doors are actuated by vaccuum and electrical wiring. pull the radio back out and look for unplugged lines or see if vent doors around the radio area are jammed or broken, could have something hung up in the wire area. when the radio is out turn on the a/c and move the vent controls and see what happens in the radio rest area checking for vent/ actuator movement

I am working on a 2003 Chevy Trailblazer and the vents just blow out warm air, and will not change to the defost vents or the floor vents. Can this be the blend door actuator? And if so where is it


yes it could be the blend door, could be broken, or the actuator, or could be the climate control too, if you know where the heater core is then you just found the blend door, goodluck. Thanks

The air condition in my 2003 trailblazier works in the back, side, and floor. The vents in the front will not blow out any air. Sometimes it works and sometimes it will not.


{: ) You can try this: Turn a/c and ignition switch off. Wait a few seconds, then turn ignition on but don't start yet. Wait forty seconds while tring to listen for some unusual noise underneath the dashboard (near the gas pedal area). Something like an air vent door getting stuck or binding.
Afterwards start the vehicle,wait another forty seconds again before you check again a/c operation. If the problem persists, the possibilities are: a faulty mode actuator, a binding air vent door, or the HVAC actuator harness. The last two possibilities may require removal of dashboard, partly or wholly. I just hope you get lucky.

2004 trailblazer dash vents fail to blow heat. All other vents work normally. I could not locate a vacuum hose that I thought might operate the upper dash vents. what do you suggest? Thank you.


this vehicle has electronic acuators that move the doors and do not use vacuum. the mode door actuator is bad causing this problem. there is a defrost acuator that works the defrost position and a mode door that works floor/vent operation. the defrost moves and diverts airflow up defrost vwents this is why you can still have defrost and floor.

2003 Chevy trailblazer, the 4 front dash air


{: ) Check first the fuse labeled HVAC1 10A at the rear fuseblock. If okay, the mode actuator could be faulty. You can try this: turn ignition switch and a/c off for a minute. Then turn ignition on, wait forty seconds. Afterwards, start the engine, and check your a/c again.

My vents on my 2004 Chevy Trailblazer won't blow heat or air


vent actuator control has lost vacume source. check for disconnected vacume lines at actuators at blend doors.also check vacume lines in engine compartment. these small vacume lines brake easily also can be deteriated near battery due to battery acid contamination

2003 Trailblazer No air from front face vents


first check to see if you have power going to the actuators when you switch the switch to it location if no power replace controller if you have power and no movement from actuators replace actuator. if actuators move remove hvac box and check for broken blend doors.
