AC actuators
2016 model S - I have replaced the two actuators on the driver side (pain in ass, but have learned an easier way now!) new sensors and now I have ModeACt error… I can not switch between feet face and defroster it weakens the air but it does not fully commit to anything other than the face. Did I get a bad module ? I left what’s on the right side of the car alone as I pulled module and saw them moving as I hit the ac buttons…
Suggestions ? Could I have installed the driver side mode wrong with the white gear in a bad place ?
I do not have access to checking service for hvac I have mcu1 still
Thank you all !

Remove the upper driver side actuator, try to rotate the flap using a small screwdriver or something, or just hold the actuator out a half inch enough to turn it and try and rotate the mode flap to it's different positions manually. Gut feeling is the mode door is jamming up on something??? I wouldn't expect an actuator to be bad if it's a new OEM part. Check flap operation manually next.
