I had this same problem on my 2003 Chevy Silverado. It is the resistor pack that is bad. Not the switch or the knob that you turn. It is loacated on the passanger side underneeth the glove box. You have to take a cover off to replace it. This is a dealer item, so you will have to get it from a GM dealer parts dept. You will also have to replace the plug that goes to it as it will be overheated. The resistor pack was about 69.00 but the plug was outrageus about 160.00. I chose not to use the plug.
Soldered on some wires directly to the resistor pack and then soldered them to the wires on the truck. Good Luck

SOURCE: 2003 silverado blower fan stays on..

under the passenger side dash, right above floor board there is a wire connector. That connector is for your blower resistor. If you unhook it, the blower will stop running, hook it back up and you will have a blower. You can also remove the fuse. Point being you can use your truck. Order the new part and replace it. I can't remember how many wires went to it off hand, its rectangular, mayber 6-7or 8ish.

2003 chevy silverado 2500hd heater fan goes on and off in cold weather


If it does it at all speeds, I would look at the controller. Loose plug or contact inside it. If it does it only in low speeds or only high, replace the resistor, behind the blower.

The heater/ac blower only works on high


Mos likely the switch on the dash for the speed settings for the blower motor has gone out. You can check this by using a test light and checking each connection coming out of the switch. If you have fire coming from all the terminals then the blower itself could be bad.

Heater fan works on high only


These trucks have what is called a "blower motor resistor". It is used to lower the voltage reaching the heater fan which results in a slower speed. It could also be a bad heater fan switch, but is likely the resistors... see it all the time.

Go to advanceautoparts.com, put your vehicle in there and do a search for "blower resistor". You'll see a picture of the part.

2003 silverado abs/brake light and service 4x4 light comes on heater blower quit working at the same time.


Possible bad ignition switch. Check out video on YouTube called 2003 Trailblazer, no blower, abs and brake lights on. I know it says trailblazer, but it applies to most of gm full size trucks. 2003-2007 including Silverado. Video tells you how to test to see if that is the problem.
