Common Causes of Dodge Ram AC Working Intermittently:
Low Refrigerant Levels
Low refrigerant levels are among the most common causes of AC problems in Dodge Ram trucks. If the refrigerant level is low, the AC may work intermittently or not. Low refrigerant levels can be caused by leaks in the system, which can occur due to damaged hoses or seals.
Faulty AC Compressor
Another common cause of intermittent AC in Dodge Ram trucks is a defective AC compressor. The AC compressor compresses the refrigerant and circulates it through the system. If the AC compressor is not working correctly, the refrigerant may not circulate effectively, leading to intermittent cooling.
Electrical Issues
Electrical issues can also cause the AC in Dodge Ram trucks to work intermittently. For example, a faulty AC relay, fuse, or wiring can prevent the AC from turning on or cause it to turn off intermittently.
Clogged Air Filter
A clogged air filter can also cause the AC to work intermittently in Dodge Ram trucks. If the air filter is clogged, it can restrict airflow to the AC system, leading to poor performance and intermittent cooling.
Blower Motor Failure
The blower motor is responsible for pushing cool air through the vents of the Dodge Ram’s AC system. If the blower motor is not working correctly, it can cause the AC to work intermittently.

How to Fix Dodge Ram AC Working Intermittently?
Troubleshooting and resolving intermittent operation of the AC system in your Dodge Ram can be approached through do-it-yourself (DIY) solutions or by seeking assistance from a professional mechanic. Here are detailed explanations of both options:
DIY Solutions:
- Check Refrigerant Levels: Begin by assessing the refrigerant levels in your AC system. If the levels are low, you can rectify the issue by refilling it. Conveniently, refrigerant refill kits are available at most auto parts stores. To prevent overfilling, diligently follow the instructions provided with the kit.
- Replace Air Filter: A clogged air filter can hinder the proper functioning of your AC system. Locate the air filter housing, typically situated on the passenger side of the engine compartment. Carefully remove the old filter and replace it with a new one. Ensure that the new filter is securely positioned within the housing.
- Check Electrical Connections: Verify the integrity of the electrical connections associated with your AC system. Examine each connection to ensure it is secure and free from corrosion. If any loose connections are detected, tighten them appropriately. In case corrosion is present, employ a wire brush or sandpaper to clean the affected areas.
Professional Solutions:
- AC Compressor Replacement: When faced with a faulty AC compressor, it is recommended to entrust the replacement procedure to a professional mechanic. This repair is more complex and requires expertise. The mechanic will carefully remove the malfunctioning compressor and skillfully install a new one in its place.
- Electrical System Diagnosis: If a suspicion arises regarding an electrical issue causing intermittent AC operation, consulting a professional mechanic is advisable. With the aid of specialized tools, the mechanic will conduct a thorough diagnosis of the electrical system. This process involves examining the wiring, fuses, and relays, while promptly replacing any defective components identified.
- System Leak Detection and Repair: Low refrigerant levels often indicate a potential leak within the AC system. Seeking assistance from a professional mechanic is crucial in this scenario. Utilizing specialized tools, the mechanic will conduct comprehensive leak detection and repair procedures. This may involve replacing damaged hoses or seals to restore the system to its optimal functionality.
Preventing Future AC Issues in Your Dodge Ram
Preventing future AC issues in your Dodge Ram is crucial to ensure that your vehicle’s air conditioning system is working correctly when needed. Here are some tips to keep your AC functioning accurately and avoid future issues:
- Regular maintenance: Regular maintenance is key to preventing future AC issues in your Dodge Ram. Follow the manufacturer’s recommended maintenance schedule and get your vehicle serviced regularly. This includes changing the air filter, checking for leaks, and replacing worn-out parts.
- Keep the cabin clean: Dirt, dust, and debris can clog up your Dodge Ram’s AC system, leading to poor performance and potential damage. Keep your vehicle’s cabin clean, and avoid eating or smoking in your car to prevent the accumulation of dirt and debris.
- Use your AC regularly: Using your AC system periodically helps prevent issues like refrigerant leaks and compressor damage caused by long periods of inactivity. Turn on your AC at least once a week, even in winter, to keep the system lubricated and operating correctly.
- Avoid overuse: Overusing your AC can cause unnecessary wear and tear on the system, leading to potential issues. Use your AC system appropriately, and avoid setting the temperature too low or leaving it on for extended periods.
- Use high-quality refrigerant: High-quality refrigerant can help prevent leaks and damage to your AC system. Stick to manufacturer-recommended refrigerant and avoid using cheap, low-quality alternatives.
By following these tips, you can help prevent future AC issues in your Dodge Ram and keep your vehicle’s air conditioning system functioning correctly for years to come.
