My car is GMC Terrain 2016, the ac system not working, it blowing hot air. I thought it was the blend door actuator which I replaced a new one but the problem is not solved.

The problem could be either electronic or mechanical. Is your compressor running? What are the high and low system pressures? The electronics would need to be diagnosed with a professional-grade bidirectional scan tool.
