Default H2 2008 HVAC error code

H2 2008 throws these codes. Anyone experienced this before? I’ve tested rear HVAC actuators seems blend door and mode actuators both working (mode door was stuck which I have to fix) I’ve run short circuit test as hooking multimeter to battery negative post and pulled all fuses related to HVAC system but no lack.
Codes are:
HVAC Control Module (VACCM) 4 problems exist

1.B0433-02

Temperature Control 3 Feedback Circuit Short To Ground

2.B3782-02

Air Flow Control 10 Feedback Circuit Short To Ground

3.B0433-61

Temperature Control 3 Feedback Circuit Actuator Stuck

4.83782-61

Air Flow Control 10 Feedback Circuit Actuator Stuck

the feedback circuit error is probably that your blend doors are stuck in a position that the reohstat is stuck on the ground side. the reohstats are what tell the motors it's travel limits. usually one side is ground the other will have a referance voltage and the wiper arms position between the 2 is it's corrolation in space like open or shut.
