Blower Motor Resistor
We will be demonstrating on a 2005 Dodge Magnum, but procedures will vary from one vehicle to the next, so be sure to know the specifics for your vehicle before getting started. If you’re not completely comfortable doing this yourself, we’d be happy to recommend a professional technician in your area.
Step 1: Disconnect Your Negative Battery Terminal
Start by disconnecting your negative battery cable. Set it aside someplace where it can’t touch metal.

Do It Right: Do It Right: If your blower motor resistor was in use before doing this job, let it cool for at least five minutes before working with it. |
Step 2: Remove the Glove Box
Next, you’ll remove the glove box. It’ll be easier to work with if you empty it first.
With the glove box open, remove the support strap from the hook on the outside.
Use a flathead screwdriver to pry the tabs on either side inward to disengage the stops, and carefully lower it.
Pivot the bin downward and disengage the hinge hooks from the instrument panel hinge brackets.
Carefully lift the glove box out from under the dash and set it aside.
Step 3: Replace the Old Resistor
Remove the screws that secure the blower motor resistor to the housing, and put them someplace safe.
At this point, you can remove the resistor from the housing.
Disengage the wire harness locking tab, and disconnect the wire harness from the blower motor resistor.
Put your new resistor in position and connect the wire harness to the blower motor resistor. Then engage the wire harness connector locking tab.
Now, install the resistor using the screws that held the old resistor in place.
Step 4: Reinstall Your Glove Box
To reinstall the glove box, engage the glove box hooks on the instrument panel hinge brackets on each side, and pivot the bin upward.
Re-engage the stops by pushing inward on both sides of the glove box, and pivot the bin into the instrument panel.
Install the support strap on the outside hook. Close the bin and make sure it latches.

Do It Right: Do It Right: If you removed any items, don’t forget to put them back. |
