I had this same problem on my 2006 colorado. when i purchased a new resistor and went to replace it, I decided to check the resistance of each position on the old one with the resistance on the new one. they were both the same. then I decided to look at the harness. I was told that it needed to be replaced as well but I decided to try just the resistor. The harness had one of the connections in the plastic connector that looked like it had over heated. (IE browned char like look) after installing the new resistor, it ran ok for about 2 days then started acting up again. Then I tried my own solution. I pulled the harness loose from the resistor and with the ignition and fan switch off took a paper clip and manuevered it under the connection with the charring and slightly bent the metal connector out. when complete, the adjusted connector appeared to be a tad too far out compared to the other connectors in the plastic. then I reconnected it to the resistor and haven't had a problem since. I did, just out of curiosity switch out the new resistor with the old one and it too also works with no problems. Of course, the dealership will not take back electreical parts that have been placed in use. This should have been a chevy recall but apparently they don't care about anything but the initial sale of their products. I sent an email to GM and got to not response.

Check the relais module located inside under the rh side of the heather box you can see the connector most of them need to be replaced as they burn out you may need to replace the blower motor as well,high amp draw caused by faulty bearings will overload the blower motor controller

No the motor is not bad or going bad, the heater blower motor resister is bad, thats regulates the blower speeds, its located under dash by heater motor 2 screws hold in heater box with a electrical plug to it.

the resister is usually located in the air box above the passengers feet ,high indicates the resistor needs to be replaced
