Chevrolet C/K truck mode and blend door actuator replacement
Here's a video covering a common repair issue on GM C/K series trucks.
If you are having problems with no heat, no cooling or air coming out from
the wrong place and you've confirmed that the control panel isn't burnt up,
then chances are you have a failed actuator.
Air door actuators are cheap and fairly easy to replace on these vehicles.
However, ensure that the control panel IS functioning and sending commands
to the suspect actuator before condemning it.
There are three actuators which do three different things, so make sure you
have identified which one is defective before buying a replacement.
1. Mode door: Mounted on end of case near driver's right foot. Controls
where airflow comes out at.
2. Blend door: Mounted on rear(tailgate side) of case roughly behind the
ashtray. Controls how hot or cold air is.
3. Recirculate door: Mounted on top of case, very hard to access. Controls
whether air is fresh or recirculated. Most people don't bother replacing
WARNING: DO NOT "TEST" ACTUATORS WITH THEM DETACHED FROM THE HVAC BOX!!!
THEY WILL OVERTRAVEL AND BE OUT OF INDEX AS YOU'LL SEE IN THE VIDEO. YOU
CANNOT REPAIR THIS EASILY, SO ALWAYS HAVE THE ACTUATOR MOUNTED TO THE BOX
BEFORE ANY KIND OF TESTING TAKES PLACE.
ALSO, INSPECT THE FLAPS THEMSELVES TO ENSURE THAT THEY ARE NOT HANGING UP.
AS WE ALL KNOW ANYTHING IS POSSIBLE WITH GM.
Blend Door? Or ... ?
Here is a video to help solve a real problem: The Heating and A/C controls
would not work. The air would only come out the Defrost Vent. Here is the
simple solution I found to solve this problem for free. Normally for such a
problem as this, you would change the Blend Door Actuator module, however
as you will see, you can first check your dash switches to see that they
are plugged in. Here is how you do it ...
Jeep Dash Removal
We are removing the dash from this jeep to fix a common problem on Jeep
Grand Cherokees. The problem is that the recirculation door breaks and
falls down on top of the blower motor causing the blower motor not to be
able to blow any air out of the vents. We show the broken parts and where
they are located in this video.
02 Ford Explorer Heat Blend Door Actuator Simple Fix - No Tools Needed
This is a 02 Ford Explorer that has a broken and worn heat blend door
actuator. The labor at a dealership with parts is approx $700-800 if you
take it to the pros, The cost of the part is approx $65.00 if you want to
do it yourself, or you can give this a try and save even more.
The part I will be referring to later in the video is a plastic flap, which
is approximately 3" long and is located almost directly behind the wires
you see in the video along the edge of the wall compartment. It needs to
be pushed down, and you will hear it as it reaches the correct position.
Once you locate this, it will only take a few seconds to change in the
The blend door will easily work with the air condition control knobs, but
once you switch it to cold air, you will need to switch this back manually
as in the video.
Hope this tip helps.

Chevy Blend Door Actuator Replacement - Part 1
This video describes the basic task of replacing one of the cooling system
blend door actuators. As described in the video, we have a 2010 Traverse
that all of a sudden started only blowing HOT air into the passenger seat.
After days of internet study, I found that it was most likely the "blend
door actuator". I found a cool parts diagram of the AC system, so knew
where to look. After finding the bad actuator, I removed it, ordered the
part, and am ready to install the working part.
How To Unclog a Heater Core - EricTheCarGuy
Heater problems in the winter suck. But with a little diagnosis you can
usually figure out the problem. Heater cores can get clogged from time to
time and this video presents a solution to that problem should you have it.
BTW, the product used in the video was CLR. If you KNOW you have a clogged
heater core this procedure is a good thing to try to help fix the problem.
However, if you are having heating problems I would suggest you check for
air in the cooling system first before performing this procedure. The #1
cause of heating problems is actually air in the cooling system. More
