This is 100% the Blower Motor Resistor, located adjacent to the Blower Motor. This is a common problem with Dodge. I had to replace my own and several dozen others on Chyrsler's, Dodge's, Plymouth and Jeep.

Make sure you disconnect the Battery and wait for 2-minutes to discharge the Air Bag System. Remove your Passenger Side - Dash -Glove Box for easier access.

Let me know if this helped...

ps....I am assuming this is the Front and not the Rear Motor...

I took the liberty to look up the Part/Availability and Price. (NO I do not work for either store/company!)

At Autozone:

Part #JA1465 for around $16.

Part #20300 for around $16.

At Advance Auto:

Part #RU1074 for around $26.

The fan motor pulled to much current causing the resister to blow and the harness/wire to melt. So for safety reasons I just replaced it all.

Blow motor resistor harness- Part is 05017124AA
Resistor- Part is 05174618AA

Here is a link with pictures to how to replace the harness and resistor.

Where is the heater resistor on a 2005 dodge dakota? Behind glove box?

should be just above the blower motor. You will need to remove the glove box door to gain access.

My 02 durango's A/C & heater fan only works on high. I bought and replaced the panel that contain the fan switch. What else could be wrong

The resistors or the relay . The resistors for all the other speeds are defective. High speed doesn't go threw a resistor that is straight B+.

Blower motor only works on high

This is a pretty common complaint and is almost certainly due to a failed heater fan resistor.
This is a stepped resistor with taps that set the different speeds on your blower and if any part of it goes bad, the whole thing doesn't work any more and the highest speed is the only one that bypasses this part.
These are often mounted on the fire wall but may not be exposed so you really need a service manual (Haynes or Chilton will do) to locate it in your car.
