Why is my AC not blowing cold in my blazer?
If your air conditioning (AC) unit is not blowing cold air in your blazer, there could be several potential reasons. The most common issues include a refrigerant leak, a problem with the compressor, or a clogged air filter. Let's explore these potential causes in more detail.
Refrigerant Leak
One of the most common reasons for an AC unit not blowing cold air is a refrigerant leak. Refrigerant is the substance that absorbs heat from the air and allows the AC to cool your blazer. If there is a leak in the refrigerant lines or coils, the system will not have enough refrigerant to effectively cool the air.
Compressor Issues
The compressor is the heart of the AC system, responsible for circulating the refrigerant and creating the cooling effect. If the compressor is not functioning properly, it can prevent the AC from blowing cold air. This could be due to a mechanical failure, electrical issues, or a problem with the compressor's start capacitor.
Clogged Air Filter
A dirty or clogged air filter can also prevent your AC from blowing cold air. The air filter is responsible for trapping dust, dirt, and other particles, but over time it can become clogged, restricting airflow and reducing the system's efficiency. This can cause the AC to work harder, leading to reduced cooling performance.
Other Potential Causes
There are a few other less common reasons your AC may not be blowing cold air in your blazer, such as a problem with the thermostat, a malfunctioning fan, or issues with the ductwork. If you've checked the above potential causes and the problem persists, it's best to have a professional HVAC technician inspect your system to diagnose and resolve the issue.
In summary, the most likely reasons for your AC not blowing cold air in your blazer are a refrigerant leak, compressor issues, or a clogged air filter. Addressing these problems can help restore your AC's cooling performance and keep you comfortable in your blazer.
Why is my AC running but not getting cold?
In some cases, clogged air filters or dirty evaporator coils can also restrict airflow, forcing the AC to compensate by running at high power. To resolve this issue, it's recommended to check for clogged filters, clean coils, and consider having a professional inspect and repair the motor or fan control components.
Is it normal for AC to not cool in summer?
If your air conditioner isn't keeping up with the heat, your air filter may be to blame. A dirty air filter can obstruct the airflow path through the unit. Using a dirty air filter can also cause less energy efficiency and more costly utility bills.

Common Reasons AC Doesn't Run Cold
The most common causes of broken air conditioning leaks or compression issues. If you are feeling cool — but not cold — air, the issue could be a clogged filter, a problem with the cooling fan, signs of radiator trouble, or it could simply mean it's time to recharge your AC.
Where is the reset button on an AC unit?
Power down your AC: Turn off your AC unit and unplug it from the power source. This will ensure that you stay safe while working on the unit. Locate the reset button: Most air conditioning units have a reset button located near the outside unit. It is usually a small button located inside a small hole.

How do I fix my AC cooling problem?
Air Conditioner Not Cooling?: Common Causes and Solutions
If your AC system turns on but doesn't blow out cold air, ensure all the vents are open and the thermostat is set properly. If these aren't the problem, check the air filter. If it's clogged with dirt or other debris, you won't get any air flow.
Why does my AC engage but no cold air?
If the compressor clutch engages and turns the compressor, but the A/C still does not blow cold air, the system is probably low on refrigerant and needs to be recharged.
How do you reset the HVAC on a Trailblazer?
Remove the HVAC/ECAS fuse for a minimum of 10 seconds. Install the HVAC/ECAS fuse. Start the vehicle. Wait 60 seconds for the HVAC control module to self-calibrate.
