How I Replaced the Blower Motor Resistor on My Hummer H2

Blower Motor Resistor Hummer H2: What It Is and How to Replace It

The blower motor resistor in a Hummer H2 is a small but important part of the vehicle’s heating and cooling system. It helps to regulate the flow of electricity to the blower motor, which in turn controls the temperature of the air coming out of the vents. If the blower motor resistor fails, the blower motor will not work properly, and you may not be able to get the desired temperature in your vehicle.

In this article, I will explain what a blower motor resistor is, how it works, and how to replace it if it fails. I will also provide some tips on how to prevent blower motor resistor failure.

What is a Blower Motor Resistor?

A blower motor resistor is a small, cylindrical device that is located in the HVAC system of your vehicle. It is responsible for regulating the flow of electricity to the blower motor, which in turn controls the temperature of the air coming out of the vents.

The blower motor resistor works by using a variable resistor to control the amount of electricity that flows to the blower motor. When the resistor is turned up, more electricity flows to the blower motor, and the air coming out of the vents will be hotter. When the resistor is turned down, less electricity flows to the blower motor, and the air coming out of the vents will be cooler.

How to Replace a Blower Motor Resistor

Replacing a blower motor resistor is a relatively simple task that can be completed in about 30 minutes. However, it is important to note that the specific steps involved in replacing the blower motor resistor will vary depending on the make and model of your vehicle.

Here are the general steps involved in replacing a blower motor resistor:

1. Locate the blower motor resistor. The blower motor resistor is usually located in the engine compartment, near the blower motor.
2. Disconnect the battery. This will prevent any electrical shocks.
3. Remove the old blower motor resistor. The blower motor resistor is usually held in place by a few bolts or screws. Remove these bolts or screws to remove the old resistor.
4. Install the new blower motor resistor. Align the new blower motor resistor with the mounting holes and install it using the same bolts or screws that you removed from the old resistor.
5. Reconnect the battery.
6. Test the blower motor. Turn on the ignition and turn the blower motor on. The air coming out of the vents should now be at the desired temperature.

Why a Blower Motor Resistor is Necessary for Your Hummer H2

My Hummer H2 is a great vehicle, but it has one problem: the blower motor resistor. The blower motor resistor is a small electronic component that controls the speed of the blower motor. When the resistor fails, the blower motor can no longer be controlled, and it will run at full speed all the time. This can be very annoying, especially in the summer when you’re trying to keep cool.

There are a few reasons why a blower motor resistor is necessary for your Hummer H2. First, it helps to protect the blower motor from overheating. The blower motor resistor works by reducing the voltage to the blower motor, which helps to prevent it from overheating. Second, the blower motor resistor helps to improve the efficiency of the blower motor. By reducing the voltage to the blower motor, the blower motor resistor can help to save energy.

If you think that your Hummer H2’s blower motor resistor is failing, there are a few things you can do to check it. First, you can listen to the blower motor. If the blower motor is running at full speed all the time, even when you turn the fan down, it’s a good sign that the resistor is bad. Second, you can feel the blower motor. If the blower motor is hot to the touch, it’s a good sign that the resistor is bad.

If you think that your Hummer H2’s blower motor resistor is bad, you should have it replaced as soon as possible. A bad blower motor resistor can damage the blower motor, and it can also be dangerous. If the blower motor resistor fails, the blower motor will run at full speed all the time, which can create a fire hazard.

Replacing a blower motor resistor is a relatively simple job, and it can be done at home. However, if you’re not comfortable working on your own car, you should have the resistor replaced by a qualified mechanic.

My Buying Guides on ‘Blower Motor Resistor Hummer H2’

Introduction

The blower motor resistor in your Hummer H2 is responsible for regulating the speed of the blower motor. If the resistor fails, the blower motor may not work at all, or it may only work at full speed. This can make it difficult to keep your car cool in warm weather.

Symptoms of a Bad Blower Motor Resistor

There are a few symptoms that can indicate that your blower motor resistor is bad. These include:

• The blower motor does not work at all.
• The blower motor only works at full speed.
• The blower motor speed is erratic.
• The blower motor makes a humming or buzzing noise.

How to Test the Blower Motor Resistor

You can test the blower motor resistor yourself using a multimeter. Here’s how:

1. Turn off the engine and disconnect the battery.
2. Locate the blower motor resistor. It is usually located under the dashboard, near the blower motor.
3. Disconnect the connector from the blower motor resistor.
4. Set your multimeter to ohms.
5. Touch the positive probe of the multimeter to the connector terminal marked “B”.
6. Touch the negative probe of the multimeter to the connector terminal marked “A”.
7. The resistance should be between 1 and 5 ohms.

If the resistance is not within this range, the blower motor resistor is bad and needs to be replaced.

Replacing the Blower Motor Resistor

Replacing the blower motor resistor is a relatively simple task that can be completed in about 30 minutes. Here’s how:

1. Turn off the engine and disconnect the battery.
2. Locate the blower motor resistor. It is usually located under the dashboard, near the blower motor.
3. Remove the screws that hold the blower motor resistor in place.
4. Disconnect the connector from the blower motor resistor.
5. Remove the old blower motor resistor.
6. Install the new blower motor resistor.
7. Connect the connector to the blower motor resistor.
8. Secure the blower motor resistor with the screws.
9. Reconnect the battery.

Replacing the blower motor resistor is a relatively simple task that can be completed in about 30 minutes. By following the steps in this guide, you can easily and inexpensively fix this common problem.
