How to Diagnose and Fix Common Dodge Ram Dual Climate Control Problems

If you own a Dodge Ram, then you know how important it is to have a working dual climate control system. But if your dual climate control isn’t functioning properly, it can be both frustrating and costly. Fortunately, with the right knowledge and tools, many common Dodge Ram dual climate control problems can be diagnosed and fixed quickly.

In this guide, we’ll discuss how to diagnose and fix some of the most common issues that can occur with your Dodge Ram’s dual climate control system.

What Is Dual Climate Control?

Dual climate control on a Dodge Ram is an innovative feature that allows you to set two different temperatures in the vehicle. With this feature, the driver and passenger can both enjoy a comfortable temperature, no matter what the weather is outside.

How Does Dual Climate Control Work On A Dodge Ram?

Climate control works by using two separate thermostats that are connected to a system of air ducts and vents. Climate control also has several settings to further customize your experience, such as defrosting and air recirculation functions. Whether you’re looking for maximum comfort during hot summer days or chilly winter drives, dual climate control provides the perfect solution.

The Dual Automatic Temperature Control system can automatically regulate the temperature inside your car based on the preferences you select. Controls for the fan’s rotation rate, airflow, the entire HVAC system, and recirculation options are all included. Just pressing the AUTO button and entering the appropriate temperature will activate automatic operation.

Moreover, this system allows for separate configurations for the vehicle’s driver and front seat passenger. Every seat has its own temperature control knob, and there’s a “Sync” button for making the controls mirror the one on the driver’s side.

The Rear Climate Control system in vehicles like the 2020 Buick Enclave functions in the same way. You can fine-tune the temperature inside your car by changing the vents in the front and back seats.

Common Symptoms & Causes of Dodge Ram Dual Climate Control Problems

Dodge Ram vehicles, equipped with dual climate control, have been known to experience a range of issues across different models and years. Common symptoms of a Dodge Ram dual climate control system can include air not blowing through the desired vent, temperature imbalances between driver and passenger, and difficulty adjusting fan speeds. Here are common causes of Ram Dual Climate Control issues.

01. A Faulty Thermostat

The thermostat controls the amount of coolant pumped into the engine and is thus responsible for maintaining an optimal operating temperature. Overheating can occur if the engine receives too much coolant if the thermostat gets stuck in the “open” position.

02. A Malfunctioning Water Pump

The water pump is responsible for recirculating coolant through the engine and keeping the coolant level constant. If the water pump fails to do its job, the engine will overheat from a lack of coolant being pumped through the system.

03. A Clogged Or Leak Radiator

The radiator releases the heat that the coolant generates. If the radiator is blocked or leaking, the engine will overheat because not enough heat is being removed from the coolant.

Symptoms includes:

04. Air Not Blowing Through The Desired Vent

One of the most common issues is air not blowing through the desired vent. This can be due to faulty sensors, clogged ducts, or a malfunctioning compressor.

It can also occur when the system is set to “auto” mode but doesn’t detect temperature change in the cabin. If you are facing this issue, it is important to identify the source and get it fixed as soon as possible.

05. Temperature Imbalances Between Driver And Passenger

This is an issue with the Dual Climate Control system, and it’s one of the most common symptoms of this type of problem. You may also experience inconsistent cooling and heating between sides, as well as a lack of airflow through the vents. If you have any of these issues, it’s important to diagnose them quickly to prevent further complications.

06. Difficulty Adjusting Fan Speeds

One of the most common problems reported by owners of the Dodge Ram is difficulty adjusting fan speeds. This can be a frustrating issue, as you may find yourself repeatedly hitting the buttons to try and get your desired level of cooling or heating

Easy DIY Solutions for Troubleshooting & Fixing Dodge Ram Dual Climate Control Issues

The aforementioned issues are only the tip of the iceberg when it comes to what could be causing your Ram’s air conditioning to quit working. The truth is that a dirty cabin air filter is just one of many potential causes of an ineffective climate control system, which also includes a broken blower motor, a loose connection, a muddled wiring harness, and so on.

Before attempting to repair the air conditioning in your Dodge Ram, you need determine the root of the problem. By employing an OBD scan tool, you may read the vehicle’s On-Board Diagnostic (OBD) trouble code and, hopefully, track down the cause of the problem.

If you’ve exhausted all other options, a technician can look over your Ford and tell you what’s wrong. The dangers of working with air conditioning refrigerants make it imperative to hire a qualified HVAC mechanic.

The air conditioner in your Dodge Ram may stop working for a number of reasons, but electrical problems are among the most common. The quickest and easiest solution is to restart the HVAC unit.

Fortunately, you can accomplish this without paying any money at all if you follow the instructions below.


  • Reduce the fan speed as much as possible.
  • Keep the air conditioning or heating button depressed for 10 seconds.
  • If the button’s lights aren’t flashing, release them and press them again.

Well, that wraps things up! When you’re done, your Dodge Ram’s air conditioning should be factory-fresh. A further investigation into the problem is warranted if the air conditioner still does not function.

When to Seek Professional Help for Repairing Your Dodge Ram’s AC

If you own a Dodge Ram vehicle, then you know how important a functioning dual climate control system is for keeping you comfortable. But when something goes wrong, it can be difficult to diagnose and fix the issue. If your Dodge Ram’s AC isn’t working properly or you’re not sure how to fix the problem, it might be time to seek professional help.

My Final Thoughts

When it comes to diagnosing and fixing common Dodge Ram dual climate control problems, it is important to take the necessary steps to ensure that the issue is resolved correctly. Knowing when and how to diagnose the issue yourself, as well as when it’s time to seek professional help, can save you time and money in the long run.

In this article, we have explored some general steps on how to diagnose and fix common Dodge Ram dual climate control problems. However, if your repairs go beyond what you are comfortable attempting or if all of your efforts still do not seem to fix the problem, then it may be time for a professional to get involved.
