Locate the blower motor and look around the outside and close to the motor for a 2-by-3-inch plate held on by two or four small screws. There will be an electrical connector plugged into it with five or six wires, depending on the vehicle type and heating and air conditioning type of control panel.
Test the resistor before replacing it. It is always recommended to test any electronic unit before replacing because there are a multitude of things that could cause the same symptoms. It only takes a few minutes and can qualify the assumption that a part is bad. It will save money to replace or repair the right part the first time.
Check the speeds by turning the fan conrol to all positions. Take note which fan speeds work and which speeds do not work. If the fan works only on one speed the blower motor resistor is very likely bad.
Check the fuses if the fan speeds do not work. The fuses for the interior heating and air conditioning fan are usually under the hood in the fuse and relay center. If the fuse looks good, then take it out and turn the ignition key on and use the volt meter set at 20 volts DC. Check to make sure that there is voltage to the fuse. If not, check for an open circuit to the fuse.
Check the relay to determine if there is power at the fuse. The relay should have two of the four terminals showing power. With the key on and the fan turned on, remove the relay and put it back in, listening for it to click. If it does not click, then replace the relay.
Check the voltage at the electrical connector on the blower motor resistor to see if the fuse and relay are good. Make sure that power is present at the connector with the key on and the fan switch on. There should be power at two terminals of the blower motor resistor. If only one terminal has power, replace the resistor. If two terminals have power, replace the blower motor itself. Remove the screws and unplug the connector to remove the blower motor resistor. Put the new one in its place by screwing it back in and plugging in the wiring connector.

It is under the hood in the heater case (passenger side), the right side of the case near the firewall as you face the engine.

Look under the dash on passenger side and just to the left of the blower motor housing you will see the 4WD control module.Remove the 2 screws holding the module and let it hang down and your resistors are behind this.Remove the 2 screws holding the resistors and remove.
Now I am assuming you have manual climate control and not electonic.

check in the duct work around the blower motor they put the there to keep them cool.

The blower motor resistor is located near the blower motor. It is held in place by 2 screws, and has a wire clip connected to it. Very simple fix.
I hope this helps you, and I wish you luck on your repair.
