Question 2003 Trailblazer Climate Control Panel

I have replaced my climate control panel with one from a used parts shop.
The one I got was from a 2003 trailblazer or envoy (who knows).
I installed it and it works for mostly everything except the two slider blend controls seem to work the opposite (blue is warmer, red is cooler).
Also, I do not seem to be able to get air to flow thru the floor vents in the
front and nothing to the rear vents. I have heard about a servo calibration or something that needs to be done when swapping controls. Is this true?
What else can be my problem?

hmmmm
the only thing I can think of... and I dont know if it will work, is to place the vents in the position that will blow hot air. disconnect battery, and then slide the thingy to the red. then reconnect.
maybe this will force it to learn that position.
ive heard of newer cars losing the vent door positions after battery is disconnected.

I think I read somewhere here that you must turn everything off after the battery disconnect and then it will recalibrate after about 15 minutes as long as you do not touch anything.

After a battery disconnect, and 2 one hour trips, I still had hot air coming out of my defroster, no matter what the setting on the controls. (Even with everything turned off)

Another battery disconnect for about 20 minutes did the trick and it works fine now.

Air flow control panel

Did the problem start with little or no flow??
Thanks Dave

Hello and Help

First off Hello! I am hoping for a little help regarding My 2003 EXT Trailblazer. My rear climate control does not respond to any of the buttons I push. I turn the fan up/down or the temp up/down and it blinks at me then goes off. Any ideas on this?
