Good morning,

I attached the procedure for you along with the pictures of the components that need to be removed.

Release the retaining clip holding the blower motor while an assistant from the passenger side compartment reaches through the blower motor cage and turns the blower motor housing 45 degrees clockwise to release and remove the blower motor.

Make sure the blower motor isn't drawing too many amps. That is a common cause of the resister going bad in the first place. This guide can help us.

Please run down this guide and report back.

If you don't know where it is how do you know it's bad?You need to see if the motor is getting power and ground if it is then you have a bad motor. If it isn't getting both power and ground then it's something else. But here is how you replace it.
REMOVAL

1. Remove the lower passenger side footwell trim.

2. Detach the floor level ventilation hose.

3. Remove the blower motor.

1. Disconnect the plug.
2. Remove the three screws.

REMOVAL

1.Remove the lower passenger side footwell trim.

2.Detach the floor level ventilation hose.

3.Remove the blower motor.
*1.Disconnect the plug.
*2.Remove the three screws.

INSTALLATION

1.Remove the middle ventilation nozzle and open the glove compartment. NOTE:
*Procedure if there is a concern over whistling noises from the heating system.
*Set the air distribution switch to "Head area" and the temperature control switch to "MAX cooling"

2.Unclip the passenger side defrost nozzle air duct and lay it down over the open glove compartment cover. NOTE: Procedure if there is a concern over whistling noises from the heating system (continued).

3.Remove the two-part plastic joining tang on the heater housing.
*Cut the joining tang at the top end using side cutters, break it off at the bottom and discard it.

NOTE:
*Procedure if there is a concern over whistling noises from the heating system (continued).
*Do not allow any parts of the joining tang to pass behind the fascia crash padding.

4.Cut the sealing tape into a 50x50 mm square. NOTE: Procedure if there is a concern over whistling noises from the heating system (continued).

5.Feel for the gap in the heater housing, affix the sealing tape over the gap from the inside and press it firmly in place.
*The sealing tape must not be applied higher than the position shown in the illustration.
*1.Heater housing (shown in cross section)
*2.Sealing tape NOTE: Apply the sealing tape in the position shown.

WARNING: SHARP EDGES ON THE HEATER HOUSING.

NOTE: Procedure if there is a concern over whistling noises from the heating system (continued).

6.Refit the components in reverse order.

You don't really test the resister itself. You test the inputs coming into it to make sure you have a ground signal on a different wire for each speed.

Sure you can

Disconnect the connector at the blower motr and check if your getting too wires that are shorted together or if any of the power wires are shorted to ground. If you have any of the above symptoms youll have to check the harness. If not check the blower motor to see if its internally grounded causing the fuse to blow.

Anything else on that circuit besides the blower motor?

It sounds like you could have a fuse that is blown here is a guide so you can help test and the fuse location in the diagrams below.
