When your Chrysler 200's AC compressor is not turning on, it can lead to a lack of cool air inside the vehicle, especially during hot summer months.
To troubleshoot this issue, start by checking the simplest and most common culprits. These include checking the AC fuse, ensuring the AC system is properly charged with refrigerant, and verifying that there are no leaks in the system.
If these common culprits are not the cause, further troubleshooting may be required. This could involve checking the AC relay, inspecting the compressor clutch, and testing the AC pressure switch. Additionally, it is important to check the electrical connections to the compressor and ensure they are secure.
If the issue persists after checking these components, it may be necessary to consult a qualified mechanic or technician who can perform a more in-depth diagnostic.

They will be able to assess the situation and identify any underlying issues with the AC compressor that may need repair or replacement.
Furthermore, it is important to regularly maintain and service your Chrysler 200's AC system to prevent future issues and ensure its optimal performance. But let us explain everything in order and in more detail.
Begin the troubleshooting process by ensuring the AC controls are set to the correct settings and the temperature is appropriately adjusted.
Confirm that the vehicle is running, as the AC compressor typically engages when the engine is on. These basic checks help rule out any simple oversights that might be contributing to the problem.
Inspect the fuse
First of all, navigate to the fuse box and inspect the fuse associated with the air conditioning system. A blown fuse could be a straightforward explanation for the compressor's reluctance to engage. This step emphasizes the importance of examining fundamental electrical components that influence the AC system's functionality.
Examine the relays
AC compressors are often controlled by relays. Investigate the relay linked to the AC system, checking for any signs of damage or malfunction.
Swapping relays with similar ones can be an effective diagnostic tool to determine if the issue persists, guiding you toward the root cause of the problem.
Refrigerant levels
Low refrigerant levels can impede the AC compressor from activating. Employ a pressure gauge to measure the refrigerant levels. If levels are insufficient, it may indicate a refrigerant leak that requires attention. This is how you can maintain proper refrigerant levels for optimal AC system performance.
Check for any leaks
Perform a visual inspection of AC components and hoses to identify any signs of refrigerant leaks. Leaks can lead to a loss of pressure, preventing the compressor from engaging. Detecting and addressing leaks early is crucial for preserving the integrity of the AC system.
Inspect the AC clutch
The AC clutch is a critical component responsible for engaging and disengaging the compressor. This section guides you through inspecting the clutch for visible damage, wear, or signs of burning. If the clutch is found to be faulty, it may necessitate replacement as part of the troubleshooting process.
Temperature sensors
Modern AC systems actually incorporate temperature sensors to regulate compressor engagement. Faulty sensors can inaccurately communicate temperature information, preventing the compressor from activating. Remember the role of temperature sensors and their impact on the overall functionality of the AC system.

Diagnose electrical connections
Examine the electrical connections to the AC compressor for loose or corroded wires. Damaged wiring can disrupt the flow of electricity, impeding the compressor's operation.
Pressure switches
It is not a secret that a lot of AC systems feature pressure switches that monitor refrigerant pressure. A malfunctioning pressure switch can incorrectly signal the system, preventing the compressor from engaging.
Scan for various error codes
Utilize an OBD-II scanner to check for relevant error codes in the vehicle's computer system. Error codes can offer valuable insights into specific issues affecting the AC compressor.
Professional inspection if needed
If all else does not work for your problem, consider seeking assistance from a qualified mechanic or HVAC technician. Professionals possess the expertise and specialized tools to conduct a thorough diagnosis and identify complex issues that may be beyond the scope of basic troubleshooting.
Why does it happen?
Hopefully, now you know how to easily fix the problem. However, we would like to discuss one more question. Why do such situations of the compressor not working arrive actually? Let us show you some of them:
Lack of cool air from the vents
One of the most noticeable signs of a faulty AC compressor is a lack of cool air coming from the vents. You may feel warm or ambient air instead, even when the AC is turned on. This can significantly impact your comfort during hot weather or when trying to cool down the interior of your vehicle.
Noisy operation of the AC system
If you notice unusual noises coming from your AC system, such as grinding, squealing, or rattling sounds, it could be a sign of a malfunctioning AC compressor. These noises often indicate issues with the compressor's internal components or the clutch assembly.
AC system cycling on and off frequently
A malfunctioning AC compressor can cause the AC system to cycle on and off more frequently than usual. This frequent cycling, known as short cycling, not only reduces the effectiveness of the air conditioning but also puts additional strain on the compressor, potentially leading to further damage.
Well, these are the most common possible reasons. Hopefully, you will be able to avoid such unpleasant situations in the future if you face them at the moment. Now let's conclude everything said above.
A few words to conclude
To troubleshoot a Chrysler 200 AC compressor that won't turn on, a systematic approach is required. This involves conducting simple checks as well as more complex diagnostics.
By following this comprehensive guide, you'll be able to identify and address any potential issues that may affect the AC system's performance.
This will ensure a reliable and efficient cooling experience in your Chrysler 200. Keep in mind that a well-maintained AC system significantly contributes to overall driving comfort.
