Step-by-Step overview on how to replace a Blower motor Resistor

Here space the simple steps the you have to follow for the straightforward replacement the a blower engine resistor:


1.Locate the Blower motor Resistor

Obviously, the first thing the you have to do is to recognize the ar of the blower engine resistor so the you understand which component will certainly be removed. The is situated right beside the blower motor. The latter, on the other hand, deserve to be commonly found underneath the dash top top the passenger side or in the engine compartment.

2.Take out the Blower engine Resistor

Now the you know the ar of the blower engine resistor, remove it. Girlfriend will require to first remove the components around the blower engine resistor, which include the pigtail associated to the AC and the blower engine cooling duct. In ~ this point, you deserve to now have actually easy accessibility to the blower motor resistor.

Now, all the you have to do is come unscrew the bolts that secure the blower engine resistor in place. Usage a ratchet with a short extension. Once the bolts are out, all the you need to do is to pull the blower engine resistor.

3.Disconnect the Wires

After pulling the blower engine resistor, you have to cut off the wires the are associated to the component. Reduced the wires utilizing the stripper or scissors that room made especially to reduced through wires.

4.Install the new Blower Resistor

Before you continue with the installation, apply dielectric grease come the housing of the blower engine resistor. This will avoid water from acquiring inside, i beg your pardon is a typical problem once you space off-road driving. Use coating around the plastic, i beg your pardon will carry out a type of sealing to safeguard the component.

Place the blower motor resistor on the exact same place where it has been earlier removed. Use brand-new screws to have actually it secured in the position. Connect the pigtail and also at this allude you are done v the job. However, there are likewise some instances inside the pigtail has currently worn out. If this is the case, continue to the next step.

5.Wire the Pigtail

Cut down the old wires and connect the brand-new ones. This need to be straightforward as the wires are probably color-coded. Use the connectors to affix the brand-new wires. Put the pigtail in its original position, and at this allude you are already done v the task.

To do the steps mentioned over clearer, refer to the short video clip that is shown below:

One the the most usual signs of failure would be when the blower engine is grounding on a single speed. Due to the fact that of this, the heater or the fan in the automobile will only role in a single setting and girlfriend will notice that the temperature go not change regardless the the adjustments the you make.There is likewise a problem if the blower engine does not work in particular settings. This can be frustrating as you can be grounding in the very same setting.Another easy means to tell the difficulty with a blower motor resistor would certainly be with performing a rapid visual inspection. If there are indications of wear, such together corrosion and also rust, that would median that you will must replace it.
You should remove the contents from the blower so that you deserve to easily accessibility the blower motor resistor. This will give you a clear vision of what demands to it is in removed.The actions mentioned above will be applicable to the removal of the blower motor resistor that have the right to be checked out in the engine compartment. If it is in the passenger seat, friend will have to remove the glovebox first so that you deserve to remove the component.You might likewise want to check the resistor first with the usage of a multimeter. By law this, you deserve to be sure that over there is without doubt a difficulty with such component and the it is inquiry a replacement.The actions mentioned above have also detailed crimping the pigtail as a essential step when the wires are currently worn. In some instances, the job might also require the need for shrink wrapping and soldering. They might require an ext effort, yet it will be an excellent in regards to making certain that it will no longer be as quickly prone come wear and tear.
