How do you install a blower motor resistor

Once the blower motor resistor fuse is located, the next step is to test if it's working properly. To do so, use a 12 Volt test light and connect it from one side to the ground and the other side to the fuse terminal.

Monitor the behavior of the power on the terminals and see if the fuse is working properly. Both terminals should have power indicating that the fuse is working just fine. However, if they don't have power, the fuses burnt and require replacement. Following the same steps mentioned earlier, make sure to unplug the blower motor and connected it to the 12 Volt test light. It's important to do the Test this way to prevent any confusion coming from components within the electrical climate control system in your vehicle.

When you perform the task, it is important to adjust the blower motor to different speeds to determine if there is any problem at certain speeds. If the blower motor is not working properly, you'll notice that it loses power at certain speeds. Keep in mind that if you set the blower motor to higher speeds and realize that there is no power, the problem can also be linked to a bad switch because, at certain high speeds, the blower motor receives the power from the switch.

If you realize that the blower motor works just fine at higher speeds but not at lower speeds, then your problem is linked to the blower motor resistor itself. Blower Motors rely on certain grounds connected to the vehicle's body, and sometimes a bad blower motor can happen due to a problem with the ground itself.

Rounds can wear out over time resulting in the intermittent function of your blower motor. Thus, if none of the mentioned tests indicated an issue with the blower motor resistor, you need to look at the blower motor ground because it might be the faulty component.

When you adjust the air conditioning speed, you're basically adjusting the amount of electrical current passing through the blower resistor motor. When the blower resistor motor does not work properly, you will notice one of the following symptoms :. When the blower motor resistor goes bad, you'll notice that the airflow coming from the vents is not going to be strong enough. Thus, if you notice that once you turn on the air conditioning or the heating system and the air is not as strong as before, you need to check the air blower motor as it might be the main culprit for the problem.

The air blower motor might wear out or get weaker over time reviews, preventing it from allowing the right amount of air to flow from the vents. Highest Level Of Integrity. Walter 46 years of experience. Request Walter. Awesome job walter.

The The timing belt is a belt made of rubber that keeps your camshaft and your crankshaft synchronized so that your valve timing is always right. Some vehicles have a timing chain instead of a belt, but it serves the Read more. The The AC condenser fan in your car works to convert refrigerant into a liquid form. Essentially, it takes heat away from your air conditioning system by delivering air to the condenser. In removing heat from the AC system, it How do I find the part number on a wiring harness?

Most wiring harnesses will have identifying part numbers in different places on the harness. The number will be on a piece of tape wrapped around the harness. If you cannot find any, then you will have to identify it by Interior driver's side door latch is broken Hello, thanks for writing in. In order to give you a proper information you will need to supply the vehicle year, make, and model to us. Otherwise we cannot give you a procedure or quote. These come with a lot of electric wires.

The house is a covering to protect these structures from effects. It also keeps the tool safe from various harmful effects. The temperature control remains stable due to such devices. Open the dashboard and each the old tool for its removal. The detachment of electric connections is necessary during such procedures.

Therefore, turn off the electric supply of your truck. It reduces the chances of errors and other such accidental conditions. The detachment of the electric wires requires pulling tools. There is an electric wire harness on the blower resistor. The tool has a connector that can join the electric passage.

Remove the connecting joint with the help of a screwdriver. Remove and detach the screws on the top of the heating box. It removes the resistor from this heating tool. Use high-quality screwdrivers according to the size and design of the screws. The accurate detachment allows the removal of the device properly.

Once you have removed all the screws, the device loosens. You can conveniently free it from the connecting joints. The tool loses the workability to work in correlation with the heat box. Disconnect the blower motor resistor assembly from the housing by pulling it gently out. You may need to remove two screws. Loosen, but do not remove the two screws on the assembly.

Remove the single rearward screw from the assembly, and remove the blower resistor. Install the new blower motor resistor. Install and tighten the rearward screw, and tighten the two front screws. You do not need to remove the slotted front screw assemblies and screws. Connect the wiring connector to the blower motor, and to the resistor assembly.
