SOURCE: locating heater blower motor resistor

the resistor is behind your glove box. open the box and push in the sides to release it and let it hang down...the resistor is right there. I didn't try to replace it, a friend did it, but the part was under $20.

If you are looking for the fan blower resistor, it is located behind the glove box. No tools need to get to it and a nut driver to remove the 2 screws to replace it. A 20$ part.

1. Disconnect and isolate the battery negative cable.
2. Open the glove box.
3. Flex both sides of the glove box bin inward near the top far enough for the rubber glove box stop bumpers to clear the sides of the glove box opening, then roll the glove box downward.
4. Reach through the glove box opening to access and disconnect the instrument panel wire harness connector for the blower motor resistor from the resistor connector receptacle (Blower Motor Resistor).
5. Reach through the glove box opening to access and disconnect the blower motor pigtail wire connector from the resistor connector receptacle.
6. Remove the two screws that secure the blower motor resistor to the evaporator housing.
7. Remove the blower motor resistor from the evaporator housing.

It is pretty much impossible for the blower resistor to be causing the blower to keep running. The blower relay, on the other hand, is very likely to cause your problem. The contacts on the relay can stick and provide power to the motor when it is not wanted. It is located in the "Integrated Power Module" (Fuse and Relay box) located on the drivers side fender area in the engine compartment. There should be a diagram on the inside of the box cover to show you which one it is.
