ac vents not putting out much air
#11
That calibration is needed after somebody that thinks they know messes with it.
Here is the correct procedure:
For the other 2 actuators (mode & recirc) be sure the key is in off position.
It is done automagically, no tech interference needed.

Update
Heres an update on my ac problem. I sold the Trailblazer that my 06 was purchased to replace so I registered the 06 and decided to tackle the no airflow ac problem. I removed the knee bolster to get access to the 2 drivers side actuators and with the car running I looked at the actuators as I adjusting the temperature and the mode settings and I could see that were both working perfectly and were within their normal range of operation. So why is there hardly any air coming out if the vents when I can here the blower blowing hard? At first I thought maybe the evaporator was all clogged up and blocking the airflow. I then remembered that the po had changed the blower motor. I wondered if maybe it was blowing backwards. I looked at the blower motor power plug and the color codes on the wires matched so it looked like it was wired correctly. I figured what do i have to lose by reversing the wires to change the blower direction Ive got no airflow now anyway. I unplugged it and reversed the wires and plugged it back in. Presto-ive got a working air conditioner!! Sorry for the long wordy post but I did want to share the solution in hopes that it may help someone else. The blower motor said "unifit" on it so I guess it may be a universal fit and other vehicles must have a different blower air direction

Oh well. I guess If the resistor ends up going out I will know thats the problem but if it was wouldn't it show up right away? Ill let you know if that crops up. Because of the way the squirrel cage mounts it only goes on one way so the vanes would have to be molded backwards. When i start using the car more ill give an update. I still have to replace the front wheel hubs before I drive it too much. One of them sounds like a 4x4 off road tire.😄
