A/C and Actuators not working properly

The A/C would fluctuate between hot and cold air when the opposite setting of heat and cold were set on the control module. I replaced all the actuators including the blend door actuators and I did the re calibration process after installation and then the compressor struggled to start up but once it did it started burning the serpentine belt. So then I started feeling cold air come out when the defrost setting was on and the re circulation actuator wasn't working anymore and neither was the mode actuator. I also tested out the rear A/C control module and its settings weren't in sync either and it would fluctuate between hot and cold vice versa to its setting. I've also replaced the main A/C control module. What i'm trying to figure out is what can I do to get all the settings on the A/C control module to function properly. I also flushed all refrigerant lines and filled them with new refrigerant and put a new climate control orifice on the refrigerant line to the accumulator.
