The issue of the driver's side heater not functioning while the passenger side works could be due to a few reasons. Common causes include a faulty blend door actuator, which controls the flow of hot air to each side, or a problem with the heating core, such as clogs or leaks affecting only one side. Additionally, low coolant levels or air trapped in the system can also lead to uneven heating. A thorough inspection of these components is recommended to diagnose and resolve the issue.
