Why 1998 Olds aurora heater half cold and hot?

A 1998 Oldsmobile Aurora experiencing uneven heating—half cold and half hot—could be due to several issues. Common culprits include a malfunctioning blend door actuator, which controls the mix of hot and cold air, or a faulty thermostat that may not be regulating engine temperature properly. Additionally, low coolant levels or air trapped in the cooling system can lead to inconsistent heating. It's advisable to check these components to diagnose and resolve the issue.
