2019 - 2023 Chevrolet Blazer Climate Control Module (OEM)

Here's what to consider when buying a replacement climate control module:

• Check Compatibility: Even though this module fits several vehicles, confirm it's the right one for your specific year, make, and model.
• Condition: If buying a used module, ask about its condition and history.
• Warranty: Look for a warranty, especially on used parts. This provides peace of mind.

Quality indicators:

• OEM Part: OEM (Original Equipment Manufacturer) parts are made by the same manufacturer as the original part, ensuring proper fit and function.
• Testing: Used OEM parts should be tested and inspected to ensure they're working properly.

What's included:

• Typically, you'll receive just the climate control module itself.
• Mounting hardware and wiring harnesses are usually not included.

Replacing the climate control module is generally a medium-difficulty job.

• Difficulty Level: Medium
• Estimated Time: 1-2 hours

Special tools needed:

• Screwdrivers
• Socket set
• Panel removal tools (optional, but helpful)

Critical steps and tips:

1. Disconnect the negative battery cable before starting any electrical work.
2. Remove the trim panels around the climate control module.
3. Disconnect the wiring harness from the old module.
4. Remove the old module and install the new one.
5. Reconnect the wiring harness and trim panels.
6. Reconnect the negative battery cable.

DIY or professional installation?

• If you're comfortable working on your car's electrical system, you can probably handle this job yourself.
• If you're not confident, it's best to have a professional install the module.

Let's compare your options for buying a climate control module:

• Used OEM: These are genuine factory parts that have been removed from another vehicle. They are tested and inspected to ensure they're in good working condition. They offer excellent value because they are significantly cheaper than new parts.
• New Aftermarket: These are brand new parts made by a third-party manufacturer. They are designed to meet or exceed OE specifications.

Both options can be good choices. Used OEM parts offer the best value, while new aftermarket parts offer the peace of mind of a brand-new component.

Consider replacing these parts at the same time:

• Blower Motor Resistor: This resistor controls the fan speed. If it's failing, it can cause fan speed problems.
• Blower Motor: The blower motor circulates air through the vents. If it's weak or noisy, it should be replaced.
• Cabin Air Filter: A dirty cabin air filter can restrict airflow and make the climate control system work harder.

Replacing these parts at the same time can prevent repeat failures and ensure the climate control system is working at its best.

A climate control module typically lasts 8-12 years.

Factors that affect longevity:

• Climate: Extreme temperatures can shorten the lifespan of electronic components.
• Usage: Frequent use of the climate control system can put more wear and tear on the module.
• Maintenance: Regular maintenance, such as replacing the cabin air filter, can help prolong the life of the module.

Here's a general idea of what you can expect to pay for a replacement climate control module:

• Used OEM: $75 - $200
• New Aftermarket: $150 - $350

Labor costs:

• If you choose to have a professional install the module, labor costs will typically range from $75 to $150.

Total job cost estimates:

• DIY (Used OEM): $75 - $200
• DIY (New Aftermarket): $150 - $350
• Professional Installation (Used OEM): $150 - $350
• Professional Installation (New Aftermarket): $225 - $500

Some vehicles in this range have known issues with the blend door actuator, which controls the temperature of the air. If you're experiencing inconsistent temperatures, check the blend door actuator as well. There may be Technical Service Bulletins (TSBs) related to climate control issues for your specific vehicle. Check with your dealer or online resources for more information.

After installing the new climate control module, verify that it's working properly:

• Check Airflow: Make sure air is flowing from all the vents.
• Test Temperature: Verify that the air temperature changes correctly when you adjust the controls.
• Listen for Unusual Noises: Listen for any unusual noises from the blower motor or other components.
• Check the Display: Make sure the climate control display is working correctly.

If everything seems to be working properly, you've successfully replaced the climate control module!
