Troubleshooting Guide: How to Fix a Dodge Durango Front AC Not Working

The most likely cause of a front AC not working on a Dodge Durango is a faulty compressor.

Dodge Durango Front Ac Not Working

If your Dodge Durango’s front AC is not working, it may be due to a variety of causes. First, check the power source for any issues; ensure that all fuses and relays are in place and working properly. If everything looks okay, then you may have an issue with the compressor. If you experience an audible noise coming from the compressor when turning on the AC, this could indicate a failed clutch or bearing, or possibly a fluid leak. Next, inspect the air flow efficiency of the unit by inspecting the ducts for any obstructions or impediments in airflow. Lastly, take a look at the refrigerant level; if it has been emptied out, you will again need to check with your mechanic to see if you need to replace or refill it. The diagnosis of Dodge Durango’s front AC issue requires serious attention and expertise; as such, seeking professional assistance is typically advised.

Diagnosing the AC Issue

When it comes to diagnosing an issue with the air conditioning in a Dodge Durango, the first step is to perform a visual inspection. This may include checking for signs of refrigerant leaks, loose or corroded wiring, and any other components that may be malfunctioning. Once any visible issues have been addressed, it is time to test the system. This can be done by connecting a pressure gauge to the low-pressure side of the AC system and monitoring the pressure readings as the engine is running. If there are any abnormal readings, then further diagnosis will be necessary.

Common Causes of AC Issues in the Dodge Durango

The two most common causes of air conditioning issues in a Dodge Durango are problems with either the air conditioner compressor or the condenser unit. The compressor is responsible for compressing and circulating refrigerant throughout the system, while the condenser unit is responsible for cooling down and condensing high-temperature refrigerant vapors back into liquid form. Problems with either one of these components can cause a variety of issues such as poor cooling performance or complete lack of cooling at all.

Inspecting and Replacing Fuses Related to AC System

In order to diagnose if any fuses related to the air conditioning system in a Dodge Durango are damaged or blown, it is important to first locate all fuses associated with this system. The fuse box containing all relevant fuses can typically be found under the hood on most vehicles; however, some vehicles may require removal of other components before access can be gained. Once all relevant fuses have been identified, they should be inspected and replaced if necessary following manufacturer instructions.

Replacing Worn Switches Related to AC System

If any switches related to an air conditioning system in a Dodge Durango are found to be worn out or malfunctioning, they should be replaced as soon as possible in order to prevent further damage from occurring. In order to identify worn switches, it is important first inspect them visually for signs of wear such as discoloration or corrosion on their surfaces. Once worn switches have been identified, replacement guidelines should be followed according manufacturer instructions for best results.

Assessing Blower Motor and Vehicle Fan Operation

It is important that both blower motor and vehicle fan operation be assessed when diagnosing an issue with an air conditioning system in a Dodge Durango. The blower motor should first be tested by turning on its power supply and listening for any noises that indicate it may not be operating correctly such as loud grinding noises or odd odors coming from its vicinity. If no abnormalities are found then next step would be testing vehicle fan operation by inspecting its blades while they are spinning; if they appear sluggish then further investigation will likely need to take place

Evaluating Refrigerant Level

If the front AC of your Dodge Durango is not working, it is important to first evaluate the level of refrigerant. This can be done by connecting a pressure gauge to the Low Side Service Port and checking what the reading is. If the reading is low, it could indicate that there is a leak somewhere in the system, and this needs to be addressed. It may also indicate that not enough refrigerant was used when the system was recharged. In any case, it is important to check this level before proceeding with any other troubleshooting.

Troubleshooting Electrical Connectors and Harness Wiring

The next step in troubleshooting an AC system that isn’t working is to inspect all electrical connections and wiring harnesses for any damage or loose connections. If any connections are broken or loose, they will need to be repaired or replaced before proceeding with further testing. Additionally, if any wires appear to be frayed or otherwise damaged, they will need to be replaced as well. Once all of these issues have been addressed, you can proceed with testing the electrical harnesses as needed.

Checking Coolant Levels in Cooling System Components

The coolant levels in your Dodge Durango’s cooling system components should also be checked when troubleshooting a non-working AC system. This includes checking for coolant leaks as well as making sure that the coolant levels are at the proper levels according to manufacturer specifications. If there are any coolant leaks present, they will need to be repaired before continuing with further testing of the AC system. Additionally, if the coolant levels are low, they will need to be topped off before proceeding with further tests on the air conditioner itself.

Testing Pressure Differential Switch Functionality

Finally, if all other tests have been completed and no issues were found with them, then it may be necessary to test the functionality of your Dodge Durango’s pressure differential switch (PDS). This switch helps regulate pressure within an air conditioning system and can often cause problems if it fails or malfunctions in some way. To test this switch you will need a multimeter and special adapters so that you can check its voltage readings while running various tests on it. If there are any abnormalities detected while running these tests, then it may be necessary to replace this switch before continuing with further troubleshooting of your AC system.

FAQ & Answers

Q: How do I diagnose the AC issue on my Dodge Durango?
A: To diagnose the AC issue, it is recommended to perform a visual inspection of the system and test it for any potential problems. This will help identify any potential causes of the issue so that you can take the appropriate steps to resolve it.

Q: What are some common causes of AC issues in a Dodge Durango?
A: Common causes of AC issues in Dodge Durangos include a faulty air conditioner compressor, condenser unit, worn switches related to the AC system, and low refrigerant levels. It is also important to check for coolant levels in cooling system components and assess blower motor and vehicle fan operation.

Q: Where are fuses related to the AC system located?
A: Fuses related to the AC system may be located under the hood or under your dashboard near your knees. Refer to your vehicles manual for specific instructions on where they are located.

Q: How do I inspect and replace fuses related to my AC system?
A: To inspect and replace fuses related to your AC system, you should locate them using your vehicles manual and then check them visually for any signs of damage or corrosion. If they need replacing, you can use a fuse puller or tweezers to remove them from their respective slots and replace them with new ones. Make sure you use one with an appropriate amperage rating for that specific fuse slot.

Q: How do I troubleshoot electrical connectors and harness wiring related to my AC system?
A: To troubleshoot electrical connectors and harness wiring related to your AC system, first inspect all electrical connections for signs of corrosion or loose connections. Then use a multimeter tester or ohmmeter tester to check the continuity between each wire connection point. If there is no continuity between two points, then this indicates that there is an open circuit which needs further investigation.

The Dodge Durango Front AC not working issue is most likely due to a lack of refrigerant in the system, a problem with the blower motor, or an issue with the air conditioning compressor. It is important to have your vehicle checked out by a professional technician who can diagnose and repair the issue.
