The blower motor resistor is defective. The resister is located under the glove compartment all the way on the right side. You do not have to remove any covers to see it. The first thing you will see is the blower motor itself. The blower motor resistor is right next to it. The only tool you will need is a Philips screwdriver. Remove the two screws that secure the resistor to the blower motor duct and pull it out. Next disconect the plug that has the wires on it. Install the connecter with wires before installing the new resistor. The blower motor resistor should cost about $25.00.
You need to replace blower motor resistor.
