CHEVY NO HEAT

2000 Chevrolet Impala

Heater problem
2000 Chevy Impala 6 cyl Front Wheel Drive Automatic 65000 miles

The blower blows cold air. Thermostat has been replaced. Coolant levels are OK. Both hoses are hot. Fuses are OK. No leaks have been found. Any idea of where we should look next?

The temperature is controlled by the use of an air mix door that is operated by an electric motor/actuator. This door can be jammed or the actuator can be inoperative or have stripped plastic gears internally.
