GM & Chevy HVAC control module

GM and Chevy's HVAC control module consists of the following parts:

Control panel
Display screen
Blower motor control
Heater core
A/C evaporator
Mode door actuators

This module is what tells all of these parts how to work together to provide you with the perfect temperature in your Suburban. A common HVAC control module would have three separate inputs: one for the temperature sensor, one for the blower motor, and one for the A/C compressor, but with GM and Chevy, there is only one input for all three. This makes it easier for the module to overheat and fail.

If your HVAC control module does fail, don't worry, ISS Automotive has you covered. We offer a high-quality replacement module that is a direct fit for your 2003 Suburban.

The remanufactured climate control module

The remanufactured climate control module is a great option if you're looking for a high-quality replacement that doesn't break the bank. We take your old module and rebuild it to work like new.

All of the parts are cleaned, tested, and replaced if necessary. Then, we recalibrate the module to match your Suburban's specific year, make, and model.

This is a great option if you're looking for a replacement that will last just as long as a brand-new one, but for a fraction of the price.

Direct Replacement for Suburban Climate Control Module

Whether you choose a remanufactured or brand-new suburban climate control module, you can be confident that you're getting a high-quality replacement. Advanced vehicle knowledge is required to properly troubleshoot, repair, and/or replace a failed HVAC control module on your own.

Having the original equipment manufacturer (OEM) part number from your Suburban's climate control module is also helpful to ensure you get the right replacement for your unit the first time.

If unsure, it is always best practice to consult with a certified mechanic or your local dealership to ensure that you are ordering the correct part for a proper fit for your specific vehicle make and model.

Common Questions for Suburban Climate Control Replacement

What does the climate control module do?

The climate control module is what tells all of the parts in your Suburban's HVAC system how to work together. This includes the blower motor, heater core, and A/C evaporator.

Connector quantity and shape can also differ between modules, so please be sure to check your part number and compare it to the pictures provided on our product pages before ordering.

If any one of these parts fails, it can cause the entire system to fail. So, if you're having any issues with your Suburban's climate control, it's best to replace the entire module.

How can you tell the climate control is not working?

There are a few signs that your climate control module may be failing. These include:

The blower motor not working
The A/C not working
The heater not working
Hot and cold air coming out at the same time
Strange smells or noises coming from the vents

If you notice any of these issues, it's best to replace the entire climate control module. Make sure to bring your unit to a trusted dealership/shop to ensure that the replaced or fixed part is working at optimal performance and has undergone proper installation.

There are a few possible reasons why your climate control may not be working. These include:
