The blower motor is located on the front passenger side below the glove compartment. You need to remove the glove compartment from the vehicle for easier access. Once removed, you will see the blower right in front of you. There should only be 3 screws holding it in place. From there, just remove it and number and wires you disconnect. Its a good rule of thumb, to replace the blower resistor and harness at the same time. If you replace just the resistor and not the harness, you likely to short out the resistor you just installed. I have an 2004 Dakota with 97k . I replaced the motor, blower resistor and harness. I haven’t had a problem since. When working on any specific part, its a good idea to replace other parts that connect to it to make it work. That way you don’t have any more problems down the line with the same part. I know sometimes, having the money to cover all the parts is difficult. So shop around for the parts. Rockauto.com, autozone, advanced auto parts, napa, o’reily or the dealer. I hope this helped you. I’m not a mechanic. I just know what works for me, and I try to help others with a related situation.
