How to replace a blower motor resistor on a Jeep Liberty?

This is a video on how to replace a blower motor resistor in a Jeep Liberty M/Y 2002-2007 (KJ). Tools required are a Phillips screwdriver (or 7mm socket), a 1/4” drive 5/16”/8mm short and if desired a 1/4” drive universal socket, a 1/4” extension with a 1/4” ratchet and a small flathead screwdriver.

What are the symptoms of a failed blower motor resistor?

Blower motor resistor problems. Problems with a blower motor resistor are common in many cars. The most common symptom of a failed blower motor resistor is when the heater fan only runs at high speed and doesn’t work at low speeds.

Why does my blower motor only work at slow speed?

Blower motor only working on low speed. Another common symptom of a faulty blower motor resistor is that the blower motor only works at slow-speed. This can be caused because of bad wiring between the blower motor resistor and the blower motor itself.

Where is the blower motor resistor located on a Ford Escape?

In the 2008-2011 Ford Escape, the resistor is located behind the glove box on top of the HVAC unit air duct. It’s held by two screws and is easy to replace. See the photo. In the 2008-2011 Ford F150 the blower motor resistor is also located behind the glove box, but is installed in the right side of the plastic air duct.

How does a blower motor resistor control the fan speed?

The blower motor resistor controls the fan speed of the blower motor and the resulting change in air pressure produced by the movement of the blower fan. It accomplishes this by regulating the electric current that powers the motor.

How much does a blower motor resistor cost?

Depending on the manufacturer and model, a blower motor resistor can go anywhere between $3 and $335 on CarParts.com. The replacement parts come in individual units, sets of two resistors, or as part of a blower motor resistor kit.

How to replace a blower motor resistor thermal fuse?

Blower Motor Resistor Thermal Fuse Replacement 1 Order the Correct Fuse. The part I ordered is from NTE Electronics. 2 Remove Old Fuse. Now the instructions say to use the crimps and only make mechanical connections. 3 Continue Removal. 4 Tin. 5 Solder the Crimps. 6 Add the Fuse. 7 Rinse and Repeat. 8 Another Shot

What causes a bad or failing blower motor relay?

Blown fuses. One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse. If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current…

How does a blower motor resistor pack work?

The way the resistor pack does this is by shortening or lengthening the circuit through the coils to add or subtract the amount of resistance it takes to get the speed you want. So naturally, three speeds, four pins.

Can a failed motor resistor cause a blower to stop?

In fact, even the diagnosis of a failed blower motor resistance is actually simple and requires no special skills or even basic knowledge, as the resistor serves only one purpose – to limit the blower to different speed settings. A failed blower motor resistor will usually cause symptoms that can be easily identified.

How can I tell if my blower resistor has burned out?

Find the blower resistor and detach it from the rest of the circuit, Once the resistor is positioned and detached, it is often possible to say whether or not the resistor has burned out or not judging by simply looking at its condition. A burned out resistor needs to be replaced via the correct alternative.

What are the symptoms of a bad heater motor resistor?

Symptoms of a Bad or Failing Heater Blower Motor Resistor. 1 1. Blower motor stuck on one speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower 2 2. Blower motor does not work on certain settings. 3 3. No air from the vehicle’s vents.
