Did it just start doing this? Many GM cars have a feature that allows the windows, radio and other accessories to operate for several minutes after the key is turned off and even removed or until the door is opened. Try opening the door and see if it goes off.

SOURCE: Blower won't shut off

I had the same problem, 2004 Silverado. If it bothers you to have the blower running while you are working on replacing the resistor, disconnect the positive batter cable before starting. I bought a BWD blower resister (part # RU1064) from Action Auto for around $28. It will work, however the mounting brackets are not the same, so I used black tape to stablize the unit. I think you COULD buy the OEM one, probably a little more $. Step by step solution as I did it:
1. Use a 7mm ratchet to remove the 4 screws holding the large plastic cover under the dash. You will need a small extention for the middle screw. Remove the cover.
2. Locate the motor resistor to the right. Using a 5.5mm ratchet, remove the 2 screws holding the unit in place. Remove the 7 pin connector from the old unit. Follow the 2 strand wire up and remove the connector from the blower. A small screwdriver is helpful for removing the connectors.
3. Connect the new, 2 wire connector to the blower. Connect the 7 wire connector to the new resistor. If you are installing the unit I mentioned, you may want to secure it with a couple of strips of black electrical tape.
4. Test the new unit to make sure all connections are good, then re-place the cover.

What is underlying cause of 2005 Toyota Corolla electrical issues. Blower motor work then not work, also continued to blow even with keys removed. Stopped working at all. All fuses good Relay melted.

This is most often caused by a failed blower motor, the brushes are worn out or sticking and not making good contact to the armature of the motor, one other possible cause is a defective blower motor switch and or connector

Blower motor continues to run after key is removed from ignition, is this the resistor?

No, I doubt if the resistor would cuase the motor to keep running. I would check the blower motor relay.

Your blower motor relay is probably stuck on. Sometimes you can tap on them and it will turn off but you will have to replace that relay.

Blower motor continues to run when vehicle is off

Your problem is the Relay which is encased inside the Heater/AC Resistor Module. This is a very common problem with GMC and Chevy Trucks. The Relay's return spring fails and the relay is held closed by gravity. The only fix is to replace the Resistor Module. I have a 2004 Silverado and have replaced the Module 3 times and the Blower Motor twice. The Orange wire feeding the Module is always Hot (12V) and feeds the Relay Contact for Highest Blower Speed. Hence the Blower runs all the time even with the Key off and removed.
