Why a Peterbilt Blower Motor Resistor is Necessary
As a Peterbilt truck owner, I’ve learned the importance of having a blower motor resistor. The blower motor resistor is a small, but important part of the truck’s heating and cooling system. It helps to regulate the flow of electricity to the blower motor, which in turn helps to maintain a consistent temperature in the cab.
Without a blower motor resistor, the blower motor would run at full speed all the time. This would not only be very loud, but it would also waste a lot of energy. The blower motor resistor helps to prevent this by reducing the amount of electricity that flows to the blower motor when the temperature in the cab is already warm.
In addition to regulating the flow of electricity, the blower motor resistor also helps to protect the blower motor from damage. When the blower motor is running at full speed, it can generate a lot of heat. The blower motor resistor helps to dissipate this heat, which prevents the blower motor from overheating and damaging itself.
If you’re a Peterbilt truck owner, I highly recommend that you keep an eye on your blower motor resistor. If it starts to malfunction, it could cause a number of problems, including decreased airflow, excessive noise, and even damage to the blower motor.
Here are a few signs that your blower motor resistor may be failing:
- The blower motor is running at full speed all the time, even when the temperature in the cab is already warm.
- The blower motor is making a loud noise.
- The temperature in the cab is fluctuating wildly.
If you notice any of these signs, it’s important to have your blower motor resistor checked by a qualified technician as soon as possible.
By following these simple tips, you can help to keep your Peterbilt truck’s heating and cooling system running smoothly and efficiently.
My Buying Guides on ‘Peterbilt Blower Motor Resistor’
What is a Peterbilt Blower Motor Resistor?
A Peterbilt blower motor resistor is a device that is used to control the speed of the blower motor in a Peterbilt truck. The resistor is located in the engine compartment and is connected to the blower motor and the battery. When the blower motor is turned on, the resistor sends a signal to the blower motor to increase or decrease its speed.
Why do I need a Peterbilt Blower Motor Resistor?
There are a few reasons why you might need to replace the blower motor resistor in your Peterbilt truck.
- The blower motor is not working. If the blower motor is not working, it could be because the resistor is bad. The resistor can fail due to a number of reasons, including:
- Overheating: The resistor can overheat if it is not properly ventilated. This can cause the resistor to fail.
- Damage: The resistor can be damaged if it is subjected to physical damage, such as being dropped or kicked.
- Electrical problems: The resistor can fail due to electrical problems, such as a short circuit.
- The blower motor is making a noise. If the blower motor is making a noise, it could be because the resistor is bad. The resistor can make a noise if it is loose or if it is rubbing against something.
- The blower motor is not blowing air. If the blower motor is not blowing air, it could be because the resistor is bad. The resistor can prevent the blower motor from getting enough power to turn on.
What should I look for when buying a Peterbilt Blower Motor Resistor?
There are a few things you should look for when buying a Peterbilt blower motor resistor.
- The correct part number. The part number for the blower motor resistor is located on the old resistor. Make sure to get the correct part number so that you get the right replacement resistor.
- The correct resistance. The resistance of the blower motor resistor is measured in ohms. The resistance of the new resistor should be the same as the resistance of the old resistor.
- The correct size. The size of the blower motor resistor is measured in inches. The size of the new resistor should be the same as the size of the old resistor.
- The correct mounting style. The mounting style of the blower motor resistor refers to how the resistor is mounted to the truck. The mounting style of the new resistor should be the same as the mounting style of the old resistor.
How do I install a Peterbilt Blower Motor Resistor?
Installing a Peterbilt blower motor resistor is a relatively simple task. However, it is important to follow the steps below carefully to avoid damaging the resistor or the truck.
1. Locate the blower motor resistor. The blower motor resistor is located in the engine compartment. It is usually located near the blower motor.
2. Disconnect the battery. Before you begin working on the blower motor resistor, you must disconnect the battery. This will prevent you from accidentally getting shocked.
3. Remove the old resistor. To remove the old resistor, you will need to disconnect the electrical connectors and remove the mounting bolts.
4. Install the new resistor. To install the new resistor, you will need to connect the electrical connectors and install the mounting bolts.
5. Reconnect the battery. Once the new resistor is installed, you can reconnect the battery.
A Peterbilt blower motor resistor is an important part of your truck’s cooling system. If the resistor fails, it can cause a number of problems, including the blower motor not working, the blower motor making a noise, and the blower motor not blowing air. By following the steps in this guide, you can easily and safely install a new blower motor resistor and keep your truck running smoothly.
