Question about 2005 Chevrolet Impala
Replace the blower motor module located under the dash on the passenger side near the blower motor. The module has a constant power supply to the high side relay. if the relay sticks the blower stays on all the time. Replacing the module is the usual fix.

SOURCE: If the fan motor from
The blower doesn't have a full time power supply. It gets power to the fan switch from the HVAC switch (the one that selects heat, a/c, defrost, vent..) and should only run if that switch is on. Also, that switch should only have power if the key is on as it is hooked to the accessory wire. Now, the accessory wire can get power if you have something plugged into the cigarette lighter that can back-feed into the system and make the car think the key is on. If you look under the dash where the steering column is, you should be able to find the accessory wire. You'll have to remove the plastic trim if it still has it. There wire is a bit thick and is orange in color. It should be around other wires similar in size with the colors of: yellow, pink, and red. The orange wire should only have voltage to it if the key is in 'run' or 'acc' positions. If you have power to it otherwise, you might just have a bad ignition switch or a short to that wire.

Check the resisitor in between the blower and the wiring under your dash.it is a small gadget. Not an electronic resistor as you would see in TV or other electronics.
