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 it.
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.

GMC Jimmy, S10, Blazer DIY How to Diagnose HVAC Mode Control - Vent - Defrost - Floor Selector
This video should provide a starting point in trying to diagnose a GMC fan
mode selection issue. My 2000 Blazer always blows air out of the dash
vents. This video demonstrates how the vacuum actuators work to divert air
from the vents to the foot wells as well as to the defrost vent. In the
next video I will test the vacuum to ensure that I have sufficient vacuum
to the actuators. Ultimately I believe that I;ll have to replace the upper
actuator, as I believe that it is faulty.
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.

1999 Tahoe HVAC Head Unit Replacement - EricTheCarGuy
Welcome back to another episode of ETCG where we boldly go where we haven't
before, taking apart the dash on this 1999 Chevy Tahoe. To be honest it
was easier than I thought, if I were to do it again I would try first
cleaning the switch and if that didn't work I would just replace the switch
for the problem this truck had. I'm learning things here too you know.

Motorized iPad 2 Install in Silverado
I decided to modify my iPad install to house an iPad 2. In order to
accomplish this, I had to cut the air vent, move the AC controls down and
fabricate a pod to house the AC controls and Kenwood headunit. I used a
linear actuator to motorize the unit. The headunit has Bluetooth and USB
input for hands-free calling and music when I don't have the iPad in the
