Hi my name is***** will be glad to try to help. Check the blend door actuators for damage or proper operation. its possible its not moving from a damaged door or faulty actuator. If okay check the heater control for sending proper signal to the actuator. Check that the AC clutch is coming on and engaging the AC compressor for cooling. If not check the system for leaks and also your fuses and relays. Let me know.

Would you be able to tell me where the fuses and relays related to air conditioning are located at?Also the bunk ac is not blowing the cold air.

I do not have the fuse chart for the 2016 but it should be in the drivers manual if not labeled on the panel itself. I usually dont look at them and test all fuses for power on both sides with the ignition switch on. Any fuses with power on one side are faulty and need replacement. For the relays I swap one at a time with a known good one ( either new or an existing one from a known working circuit) for test purposes. Let me know
