Common Chevy Silverado Climate Control Problems
1. Dual climate control issue
We had to start with this issue because it is the most common issue that Silverado owners experience.
The dual climate control issue usually manifests itself when one side, either the drivers or passengers blows cold air and the other blows hot air.
This usually happens even when you have instructed the system to produce either cold or hot air on both sides.
The reason we have listed this as the most common problem is that if you read through various Chevrolet forums, you will realize that many people have reported this issue.
Considering how rampant this issue is, by now, Chevrolet should have at least attempted to fix this problem in newer models.
Only time will tell if Chevrolet has taken note of this problem and prevented it from happening in the 2021 Silverado.
Fortunately, because this issue is quite common, Chevy Silverado owners have devised a couple of ways to fix this problem.
If you are experiencing dual climate control issues, the first thing you need to do is re-program the climate control equipment. To do this, unplug the battery cables for about 10 minutes.
Put them back on and insert your key, but don't turn the car engine on. Move the key to the on mode, wait for 5 seconds before turning it off.
Repeat the on and off process thrice and this should re-program the climate control problem.
The dual climate zones in your car are controlled by temperature actuators on both sides. When you reprogram your car climate controls, the actuators are re-started and this may solve your issue.
However, if you still encounter this problem, then you may have a bad actuator that needs to be replaced right away.
2. Inability to control the type and intensity of air coming into the car
Though not as common as the above problem, if you find it impossible to control the climate in your car, then you may be dealing with a dead actuator.
Air also won't be able to come into your car when you have a faulty fan motor. With the latter, however, you will hear some noises when you turn the climate controls in your Chevy Silverado.
Also, another reason as to why you may not be able to operate the climate controls in your car is when you are dealing with a blown fuse.
Under your hood, there is a fuse box that contains many fuses which play various electrical functions. If the one that has been assigned to control AC in your car is blown, you will have to replace it.
In most Silverado's the biggest culprit for this problem is often a faulty fan motor. The guys at the dealer can easily replace the motor for you.
3. AC only blowing hot air
There have been reports that the AC in some Silverado's blows only hot air even when set to blow cold air.
This can be a menace especially when you are driving in summer and want a cold breeze, only for you to get more hot air.
From most reports, this problem often pops up randomly. And there are times when it may produce cold air for a while and then switch to hot air.
If this happens when you have set the climate controls on auto, then you may have a faulty temperature sensor that will need to be replaced.
However, if this happens even when you have instructed the climate controls to only blow cold air, then you will have to reprogram the system and actuators.
Should this remedy not work, you will have to take the Silverado to your mechanic or nearest dealer and have them inspect the mechanical features of your car's AC system.
4. Climate control panel not working
With time, especially when your truck hits the 100K mileage, certain issues often start to creep in. one of them is a faulty climate control panel.
The first sign that your climate control panel is not working is when there are no lights on the knobs or controls. And if this is the case, check the fuse box first. A dead fuse can cause a total malfunction of the climate control panel.
Please refer to your manual regarding the arrangement of fuses in your Silverado fuse box. The other thing you should check is the HVAC control module.
It has 4 connectors. Confirm if all the connectors are plugged into the control module.
These are the main climate control problems you may encounter on a Chevy Silverado. Most of these problems are unpreventable and you just have to be always on the lookout for any signs and symptoms.
Climate control systems are designed to enhance convenience and luxury when one is driving. So, if yours is malfunctioning, identifying the cause is key as it helps you find an immediate solution.
Can Resetting the AC Solve Most Chevy Silverado Climate Control Problems?
Most climate control problems can indeed be resolved by resetting the AC. This however applies to software-related problems and not mechanical issues.
If an actuator is misbehaving then reprogramming the AC can help. However, if your climate control fuse is blown, you just have to change it. Resetting the AC is not going to fix it.
So, how do I reset the AC on a Chevy Silverado? It's pretty simple. The first thing you need to do is locate the HVAC fuse. This is located in your fuse box under the hood.
After identifying it, with the ignition switched off, remove the fuse for about 10 seconds. Put it back in and wait for 40 seconds for the AC system to reprogram itself. Switch the car on and see if your climate control issues have been resolved.
The above is how to reset the AC. Did you know that you can also reset climate control?
To do this, you will have to start the car and then press the lowest and highest buttons on your AC control panel until the ASC light begins to flash.
Release them at the same time and your system will undergo a complete reset. This should as well fix minor Chevy Silverado climate control issues.
Signs of a Faulty Door Actuator in a Chevy Silverado?
If you have realized some inconsistency with the airflow or you are hearing a knocking sound on the door of your Silverado, the door actuator can be faulty.
To know if it's faulty, you will have to remove it from the door and have a look. Signs of wear should be an indication that it needs replacement.
Actuators can be very tricky to diagnose. Plus, you may think that the problem is with an actuator only for you to find out the cause of your climate control woes is the motor.
Because of these reasons, most people prefer to have the vehicle fixed by an expert. This is a process that takes less than two hours. In some cases, a faulty actuator can affect both the climate control and door lock mechanism.
What about Failed Sensors?
Though not a common issue in Chevy Silverado, you shouldn't ignore the role of temperature sensors in your car. These are responsible for determining the type and strength of air entering your car.
Silverado's feature two sensors, one located outside and another inside. These two work together to ensure you get the most ideal climatic conditions in your car.
If your sensors are failed then your climate control will behave strangely.
Other Chevy Silverado Problems
Now that you are familiar with this car's climate control issues, it's important that you also find out other problems that have been reported against this car model.
We have scoured the internet and found the following to be the most common problems with the Silverado;
- Transmission issues – This is very common in the 2017 model and it is often characterized by jerking and surges. In some cases, owners have had to replace the transmission even before the car reached the 100,000 miles mark.
- Burning oil – It mostly affects the 2009 and 2008 models.
- Knocking noises coming from the engine – Which has been mostly reported in the 2000 model.
Out of all the Chevy Silverado models, 2004 has received the most complaints ranging from malfunctioning interior features to speedometer issues.
If you plan on buying a used Silverado, be very keen on the 2004 model.
However, since 2018, the Silverado line has received fewer complaints related to climate control and other common issues. This is a sign that Chevrolet is doing a job.
