Recently,on my 2012 Buick Enclave, the left side was blowing cold air, the right side blowing warm air. I changed out the right side air actuator, not the easiest thing I’ve ever done, and after starting the vehicle,I’m not noticing any difference.I made sure everything was aligned and replaced properly.A “ buddy” of mine says it needed to be “reset”. Please tell me that there’s a simple fix.

More than likely the problem is with the HVAC control module.
