Your problem is most likely an actuator.These actuators require a recalibration ,if power is ever lost or disconnected.I would start with a recal process.If your control is still not responding correctly,you should scan the body control system with a class 2 scan tool .There very well may be codes set,some of these codes will cause the controlling computer to go to a default setting.

Important: The module memory will not clear if the battery positive voltage circuit fuse is installed in less than 60 seconds.

I sent reply hope it got thru. i'll try again. I rechecked 5 actuators that I found. I removed motors and manually opened and closed doors on 3 XXXXXside 1 on passsenger
no difference. 1 behind glove box do not know what it controls but it moves 1 for rear air moves. driver air about 30- 40 f hotter than passenger side on cooling. cooled air must be mixing with heated air on driver side. recalibration didn't help. any more ideas. thanks
Have you checked the BCM for failure codes & viewed data from a/c system ?
Did you use an output test on a class 2 scan tool to run the actuators full scale ?
there are no codes showing.
do not have scan tool , but with dash disassembled I can watch them open and close
I am sending information for the air mix actuators for driver & passenger sides to help you.Your question has not been accepted.

Caution: When you are performing service on or near the SIR components or the SIR wiring, you must disable the SIR system. Refer to Disabling the SIR System. Failure to follow the correct procedure could cause air bag deployment, personal injury, or unnecessary SIR system repairs.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten Tighten the fasteners to 1.4 N·m (12 lb in).
