2011-2018 Dodge Durango A/C Control Module: A Guide to Failures & Compatibility

Symptoms of a Failing A/C Control Module 🎬 Watch this overview of common bad climate control module symptoms

When the A/C control module in a 2011-2018 Dodge Durango begins to fail, it can cause a range of frustrating issues. Because the module controls the entire system, symptoms can sometimes be mistaken for other problems like a bad blower motor or a refrigerant leak. Always start with the simplest checks, like inspecting fuses, before assuming the module is at fault.

• Unresponsive Controls: Buttons, dials, or touch-screen functions do not respond, or there is a significant delay. You might not be able to change fan speed, temperature, or the direction of airflow.
• Incorrect Temperature Output: The system blows hot air when set to cold, or cold air when set to hot. It may also produce brief bursts of hot or cold air after an adjustment.
• Fan Speed Issues: The blower fan may be stuck on one speed (often high), not turn on at all, or cycle erratically on its own, especially in "Auto" mode.
• Flashing A/C Light or Display: A blinking light on the A/C button or a flickering control panel display can indicate that the system has detected a fault and shut down.
• Loss of Dual-Zone or Rear Climate Control: One side of the vehicle may be a different temperature than the other, or the rear climate controls may stop working entirely.
• System Shuts Off Randomly: The entire HVAC system may turn off during operation, sometimes during a cold engine start, requiring you to manually turn it back on.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While there are no direct recalls for the A/C temperature control module itself on the 2011-2018 Durango, several Technical Service Bulletins (TSBs) have been issued by Dodge to address software-related HVAC problems. These bulletins instruct dealers to reprogram the module to fix specific issues.

• TSB 24-004-17: Released for 2014-2015 models, this TSB addresses several customer complaints including the HVAC system shutting off during a cold start, erratic blower speeds in auto mode, and brief bursts of hot or cold air after changing the temperature. The fix is a software update for the HVAC module.
• TSB 24-009-19: This bulletin applies to 2019 models but is relevant as it shows a pattern of software issues. It addresses a condition where the controller overheats the cabin during a cold start. The fix is to reprogram the HVAC module with updated software.
• Customer Satisfaction Notification R62: While for a different vehicle (Grand Caravan/Town & Country), this notification is a good example of how FCA addresses widespread HVAC issues. It involved reprogramming the module to prevent blend door actuators from binding and failing, a common issue across many vehicles.

No major safety recalls specifically target the front A/C control module for this generation of Durango. However, always check for any outstanding recalls on your vehicle by VIN.

Buying a Used 2011-2018 Durango A/C Control Module: The Definitive Checklist

Purchasing a used A/C control module is an excellent way to save money, but it is absolutely critical to get the exact correct part. The Durango was offered with a vast number of feature combinations, and the control module must match your vehicle's original equipment perfectly. An incorrect module will not work.

Step 1: Match Your Vehicle's Options EXACTLY

This is the most important step. The module is programmed to work with a specific set of features. Before you even look for a part number, you must know which options your Durango has. Look for a used module from a donor vehicle with the identical feature set.

Verify these options on your vehicle before buying:

• Temperature Control Type: Does your vehicle have Automatic Temperature Control (ATC) where you set a specific temperature, or manual controls with simple blue-to-red dials?
• Seat Features: Does your vehicle have Heated Front Seats only, or does it have both Heated AND Ventilated (Cooled) Front Seats?
• Screen Size: Is your Durango equipped with the 5.0-inch, 7.0-inch, or 8.4-inch Uconnect touch screen? The control module is different for each.
• Park Assist: Does your vehicle have rear park assist sensors? The button for this feature is integrated into some control panels.
• Rear A/C: Does your vehicle have a separate climate control system for the rear passengers?
• Engine Stop/Start: Does your vehicle have the automatic engine stop/start feature? The button for this is also on the control panel.

Step 2: Verify the Part Number

Once you have confirmed the options, try to match the part number from your original module. You can find this number on a sticker on the unit's housing after removal. While many part numbers exist and some may supersede others, matching the number is the safest way to ensure compatibility. If you can't get your original number, provide the seller with your VIN and a detailed list of your vehicle's features.

Step 3: Physical Inspection Checklist

When you have the used part in hand, inspect it carefully:

• Buttons and Knobs: Press every button and turn every knob. They should move freely without sticking and have a solid, tactile click. Check for excessive wear on the button graphics.
• Connectors: Look at the electrical connector ports on the back. Ensure there are no bent or corroded pins and that the plastic housing isn't cracked or broken.
• Mounting Tabs: Check that all plastic mounting tabs are intact. Broken tabs will result in a loose, rattling fit in your dashboard.
• No Signs of Liquid Damage: Look for any sticky residue or discoloration, especially around the seams or in the connector ports, which could indicate a spilled drink caused the original failure.

Cost Comparison: New vs. Used

The cost of replacing an A/C control module can vary significantly depending on the source of the part.

Replacement Guide

Replacing the A/C control module in a 2011-2018 Durango is a relatively straightforward job suitable for a DIYer with basic tools.

• Difficulty: 2/5
• Estimated Time: 30-60 minutes
• Tools Needed: Plastic trim removal tools, Phillips screwdriver or 7mm socket.

Step-by-Step Overview

1. Disconnect the Battery: Before starting any electrical work, disconnect the negative terminal of your vehicle's battery to prevent short circuits.
2. Remove the Center Stack Trim: 🎬 See how to remove and replace a Dodge climate control panel Using a plastic pry tool, carefully pry away the large trim piece that surrounds the radio and climate controls. It is held in by clips. Start from the bottom and work your way up.
3. Unscrew the Control Module: The A/C control module is typically held in place by two or four screws. Remove these screws.
4. Disconnect and Remove: Gently pull the module out from the dash. Press the release tab on the electrical connector(s) on the back and pull them straight out. The module is now free.
5. Install the New Module: Connect the electrical harness to the new module, slide it into place, and secure it with the screws. Re-attach the center stack trim by aligning the clips and pressing it firmly into place.
6. Perform Calibration Procedure: 🎬 Watch how to calibrate blend door actuators on a Dodge Reconnect the battery. A calibration procedure is often required for the system to learn the positions of the new actuators and controls.

Post-Installation: HVAC Calibration Procedure

After replacing the module or disconnecting the battery, the HVAC system may need to be recalibrated. This allows the control module to learn the full range of motion of the blend doors. While procedures can vary slightly, a common method is:

1. Turn the ignition to the 'ON' position (without starting the engine).
2. Wait for 1-2 minutes. During this time, do not touch any of the climate controls. You may hear the blend doors moving behind the dash as they cycle through their positions.
3. After two minutes, turn the ignition off, then start the vehicle and test all functions of the HVAC system—temperature, fan speed, and all vent modes.

If this simple relearn does not work, a more advanced calibration may need to be performed with a diagnostic scan tool.
