blower speed control

2005 g6 ,it only blows aire.hot/cold in the last speed control(1,2,3, speed is not working)?

If you have a manually controlled system the blower motor resistor must be your problem. It is located on the blower motor. Not sure about your model but should be located on the passenger side under the dash.

By the way Welcome to the forum!
