Blower motor will not operate.

There are only a couple of things that could cause this issue, and I would start with the simplest thing first, and that is to check your fuse panel. Your blower will operate only on high because it is wired to do so on the number 4 setting as it bypasses the blower motor resistor. If the fuses are good, then the blower motor resistor is the next step, and this can be found close to the blower motor, as the blower motor, when on, cools the resistor, when the resistor gets old and to hot, it will blow, thus causing your fan to only work on high. If the resistor is good, then the last thing that you would check is the fan selector switch. I seriously doubt that it is the switch, it is usually the fuse, or the resistor.

OK. So the blower notor isn't operating. Do you have power to the blower motor? The resistor is new from what I got. If you don't have power to the blower motor, then check the speed control switch and fuses. If you have power at the blower motor, replace the blower motor

In the Dodge Dakota the blower motor resistor is located under the hood, on the right side firewall.

Dodge Dakota Blower Motor Resistor Location:



Dodge Dakota with a complaint of no blower operation. After unplugging the harness connector and removing the two screws, you could remove and examine the resistor coils for damage. The heat and subsequent rust damage are clearly visible in the picture below.

Try replacing the fan resistor they are about $40.00. The resistor is located on the side ( usually the underside ) of the heater box under dash below the glove box.

The front blower motor is controlled by the blower resistor module.This is usually the problem with the front blower not working.I looked up the schecmatics and I don`t see separate fuses for the front and rear.But the fuse for the front blower is in the under hood fuse block.If this is good then The problem is probably the resistor module.It is next to the blower motor.The connector from the resistor connects to the blower motor.If you want to confirm this you can check for power and ground at the blower motor connector when you activating the blower switch on.This can be done with a test light.Make sure you have power going into the resistor module also.If you have power going in and no power at the blower motor then replace the resistor.Hope this helps.Good luck.

Check the blower motor speed control resistor pack is ok.
(The resistor pack is usually located in the blower fan ducting in the air flow).
Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen.
Check operation/replace any blower motor control relay,
Check the blower motor will run if +12v directly applied to the blower motor.
Check operation of the blower motor speed control switch is ok.

Check the blower multispeed control resistor pack is not faulty.
The resistor pack is usually located in the air ducting, in the blower fan airflow.
Basically, +12v power is supplied (via fuse) to the fan speed control switch, which then passes via the selected speed control resistor, to the fan motor. Often a interface relay is used to switch the blower motor high current.

Check fuse supplying fan is not blown,
Check blower control switch is operating OK,
Check relay controlling fan is operating OK,
Check variable speed resistor pack is not faulty (the resistor pack is usually located in the blower ducting, in the blower airflow),
Check blower motor ground connection is not missing.

its under your pass side dash but start with the resistor first put your blower motor on high and push around on your resistor under your glove box,if it will come on by moving it around its your resistor

The thermistor is in the winding of the blower motor. Letting it cool down will let it run, but probably not long. the thermistor is not replaceable, replace blower motor
