If you are referring to the blower motor resistor then it is inside mounted on the evaporator case.
There is only one blower motor resistor and it is located in the evaporator housing.
It is located under the dash on the right side in the evaporator case.
Recommend you check the blower motor resistor.
Replace the blower motor resistor.
faulty blower motor resistor
If your wondering because you only get a 2 or 3 selection for blower instead of 5. and your replacing blower resistor, im told go behind glove box? never tried it. The blower motor is directly above the glove box. Directly in front of that is the resistor for your ac/heat.
i had a 03 Chevrolet Colorado, and the resitor was located under the glove compartment, where the motor blower is, the resistor is screwed to the side of the blower. hope this works for you. the resistor is usually located there.

You either have a blown fuse, defective blower motor, defective blower motor switch, or a defective blower motor resistor pack.
It is under the hood on the passenger side firewall.
