Question about 2004 Chevrolet Silverado
HI. This will be the cause of a defective resistor switch. The speed variables have been damaged. This will happen, overtime. The necessary action will be to have this damaged switch replaced. This will be the actual switch that is located, and housed within the control cluster in the dash.(Speed selection switch)

You have a problem with the resistors on your blower motor. 95% of AC/Heater blower motors are located under the glove box in the passanger foot well. When you remove the motor you should see a resistor plate. Resistors are not servicable and will need to be replaced. This is a relatively cheap part, that you can replace yourself if your handy, if not take it to your local tech.

Its the Blower Resistor....If it was the switch, it probably wouldn't work at all....But the Resistor will give you those symptoms, of working on high med or low

check the coolant level possible leak at the intake manifold very very common problem on gm v6 or possibly your themostat is sticking and the increased rpm could force it open
