Question about 2004 Dodge Dakota

2004 Dodge Dakota

Blower motor worked only om high speed for a while, now doesn't work at all. I replaced control switch still didn't work. I ran 12 volt wire to positive side of blower motor blower ran fine. I checked for voltage on blower resister, no voltage. I checked for voltage on blower 12 volt wire 12 volts present. I automatically think, bad ground. I ran temporary body ground to ground wire on blower motor, blower ran high, but would not shut off. I am unable to find wiring diagrahm for blower circuit. Do you have any suggestions? It's cold here!

    I eliminated the problem down to the resister. I figured out that the blower speeds are controlled by a variable ground. This should have been disclosed by someone before I had to go through all the grief. In the future remember blower resister varies the ground not voltage. The presence of voltage"12 volts" does not mean the resister is OK. Thanks for giving me a chance to give input.

Replace your resistor if you haven't already. I had the same issue with mine, it only worked on high.

This is definitely the Blower Motor Resistor located near the Blower Motor. It is defined with 3-4 wires going into it. It is easy to remove and replace. Purchase the part at the auto parts store versus at the dealer to save you a lot of money.

Limited heat


first, check the fuse for the blower motor. If ok, you may have a bad switch or bad blower motor. If you are a techie, you should jumper 12 volts to the blower motor hot terminal. see if it blows then. You also have a blower motor resister that gives you the 4 blower speeds, but usually when it fails, you have high speed only.

good luck

The heater/defroster/ac switch


Sounds like a card located under dash behind your blower motor, on passenger side.When card starts going bad you will only have off and high (for awhile), then none. change the card, this thing controls your speeds on the motor at your control on dash. I have a 2002 Dakota had same problem... but keep in mind not all Dakotas have this card.
