Chevy Silverado Climate Control Problems

Chevy Silverado Climate Control Problems

Chevy Silverado is a durable truck with incredible features. The most notable is a powerful engine capable of conquering even the toughest terrains. The trims are also many; each promises good legroom, high-tech safety features, and excellent towing capabilities.

Although Chevy Silverado has loveable features, it has its drawbacks, like any other truck. This article discusses Chevy Silverado’s climate control problems. Stay tuned!

Common Chevy Silverado Climate Control Problems 

The dual climate control problem is the most common climate control problem with Chevy Silverado. This problem occurs after you instruct the system to produce hot or cold air on both sides. It presents itself by having one side of the car, the passengers or drivers, blow hot air and the other side cold air. 

The dual climate control issue is rampant, with many people reporting it. Fortunately, the rampant reporting caught the manufacturer’s attention, and they developed a way of fixing the issue.

So, if you’re having the dual climate control issue, there’s a way of fixing it. Start by reprogramming the climate control equipment. Unplug the battery cables for around 10 minutes. Then return them and insert your key. However, don’t turn the engine on. Instead, move the key to the on mode, and wait for exactly five seconds before turning it off.

Repeat the process (of turning on and off) three times. After the third time, your climate control problem should be reprogrammed.

Note that temperature actuators on both ends control the dual climate zones in Chevy Silverado. So, when you reprogram your car climate controls, the actuators are also re-started in the process, solving the problem.

Sometimes you may do the above process, and still, your dual climate fails to work well. In such a case, your actuator could be the problem and may need replacement.

AC Blowing Hot Air Only

Another climate control problem of Chevy Silverado is the AC blowing hot air only. Imagine taking a ride in your vehicle on a hot summer afternoon, and your machine decides to blow hot air only instead of cold.

According to most people, this issue usually happens randomly, out of nowhere. And there are instances when the AC produces cold air for some time, then switch to hot air.

Suppose you encounter this problem and you have set your climate control on auto; you may have a faulty temperature sensor. And thus, you need to replace it.

However, if the issue occurs when you have commanded the climate controls to blow only cold air, you may consider reprogramming the system and actuators.

In case this remedy fails to work, consider taking your Chevy Silverado to the nearest dealer or your mechanic, who will inspect the mechanical features of the car’s AC system.

Unable To Control Type And Intensity Of Air Entering The Car

The inability to control the intensity and type of air entering your car may not be a common issue, but it happens. If you experience this fix in your Silverado, you may have a dead actuator.

If you have a faulty fan motor, air would be unable to get into your car. However, it’s easy to distinguish this issue from the dead actuator one. When you have this issue (faulty fan motor), you’ll be able to hear some noises when turning the climate controls in your Chevy Silverado.

A blown fuse is also another reason for the inability to operate the climate controls in your car. A fuse box is located under your hood. This fuse box contains several fuses, and each one of them has a unique electrical function. If the fuse assigned to control AC in your Chevy Silverado is blown, you will have to buy another one.

All these issues can interfere with the ability to control the type and intensity of air getting in your car. However, the most common problem in Chevy Silverado is a faulty fan motor. A spoilt fan motor is easy to replace at your nearest car dealer.

Climate Control Panel Not Functioning

As with anything, your Chevy Silverado will wear and tear with time, especially when it hits the 100k mileage. When your truck hits 100k mileage, issues will start coming one after another. The most notable problem is a faulty climate control panel.

Various signs can show your climate control is not functioning. For instance, when there are no lights on the controls or knobs. If there are no lights on the knobs or controls, begin by checking the fuse box. A dead fuse box can result in the complete malfunctioning of the climate control panel. And the best thing to do here is to refer to your manual on the proper arrangement of fuses in the Silverado fuse box.

Another thing you need to check is the HVAC control module which consists of 4 connectors. Ensure that all the connectors are inserted in the control module.

Should You Reset Your Silverado AC To Solve Climate Control Problems

Although most climate control problems can be fixed by resetting the AC, they are software-related issues, not mechanical ones. Software-related issues like a misbehaving actuator can be fixed by reprogramming the AC. However, Mechanical issues cannot be fixed by resetting the AC. For example, resetting the AC cannot change a blown climate control fuse without replacing it, etc.

Resetting Chevy Silverado is easy and shouldn’t hassle you. Locate the HVAC fuse found in the fuse box under your hood. Once identified, turn off the ignition and remove the fuse for ten seconds. Return it and wait for forty seconds for the Ac to reset itself. Switch on the car and determine if the control climate issues are resolved.

Reprogramming climate control is also straightforward. Start your Silverado and press the highest and lowest buttons on the AC control panel until lights start flashing. Release the buttons, and your system should reset itself. Reprogramming should fix other minor Silverado climate control issues.


The purpose of climate control systems is to give you convenience and make your ride comfortable. So, anytime you encounter climate control problems, find the root cause and fix the issue.
