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.
