New here. Having some rear A/C issues on 05 Escalade and 12 Denali

[Mackdaddy]

I have a 2005 Cadillac Escalade where the air conditioner control module in the rear would only put out fan speed. I have one bad actuator and one good actuator when I put the new module in. I have no fluctuating output to the Temperature actuator after replacing the control module. Has anybody tested the input side and maybe have a pin out?

My other problem is on my 2012 Denali, I have the same problem and cannot find any information where the actuator is mounted. I took it off the interior and it’s bare on the side where I thought it would be. See picture attached. Can someone tell me where is mounted because I can’t find it anywhere on the Internet?
