I am only getting heat from the passenger side. I have a Tahoe with the Dual digital controls. I tried re-calibrating and it did not fix the problem. What else can I do or do I need to replace parts?
When I did the re-calibrating I did see gears under the dash on the driver side working properly but after the process still cold air blows and not hot.

Please help me.

First check the engine coolant level.

If okay move onto checking the operation of the driver’s temperature door actuator located under the passenger side of the dash. There is a high probability that the actuator has failed.
