A/C Comressor Runs in Heater Mode

2009 LT: When I select the floor outlets the compressor runs. Snowflake button is not lit and recirculation mode is off. Relay has been replaced. I don't think the compressor is supposed to run in heater mode.

Compressor will run in heat mode if the button isn't all the way in floor mode. Try it one notch further counterclockwise. Any position in defrost will turn the compressor ''ON''.
