2017-2019 Chrysler Pacifica Door Module: Solving Power Mirror and Programming Problems
This guide covers the common failures, critical programming requirements, and compatibility checks for the front passenger door control module in your Chrysler Pacifica.
- A replacement Door Control Module MUST be programmed to the vehicle using a procedure called a Proxy Alignment to function.
- The module is specific to the vehicle's options. You MUST match the part based on whether your Pacifica has power-folding mirrors.
- Multiple part numbers exist due to supersessions; it's best to use the latest version (highest letter suffix) that matches your vehicle's features.
- Before replacing the module, always check fuses and the door wiring harness for damage, as these can cause similar symptoms.
Symptoms of a Failing Pacifica Door Module
When the front passenger door control module begins to fail, it can cause a variety of frustrating electrical issues. Because the module controls multiple components, you may notice one or several functions stop working at once. The failure is almost always isolated to the front passenger door.
- Inoperative Power Window: The front passenger window will not go up or down when using either the driver's or passenger's switch.
- Power Lock Failure: The passenger door lock does not respond to the key fob or the interior lock buttons.
- Power Mirror Issues: The passenger side mirror cannot be adjusted, will not fold, or the heated mirror function stops working.
- Blind Spot Indicator Malfunction: The warning light in the passenger mirror may stay on, stay off, or not function correctly.
- Keyless Entry Failure: The button on the exterior passenger door handle may stop locking or unlocking the vehicle.
- Intermittent Functionality: Any of the above symptoms may happen randomly, working one moment and failing the next. This can sometimes be triggered by temperature changes or vehicle vibrations.
Associated OBD-II / Fault Codes
A professional scan tool that can read Body Control Module (BCM) and manufacturer-specific codes is often necessary to diagnose a faulty DCM. While generic code readers may not see these, a more advanced tool might show codes related to lost communication or circuit faults.
- U0140: Lost Communication With Body Control Module
- B18BA-12 / B18BA-13: Window Control Circuit Short to Battery or Circuit Open
- B210D: Battery Voltage Low (can be set if the module has a power supply issue)
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
While the front door control module itself has not been the subject of a specific recall for the 2017-2019 Pacifica, Chrysler has issued TSBs for related door systems that involve software updates to various door modules.
- TSB 08-087-16: This bulletin for the 2017 Pacifica involves reprogramming the Power Sliding Door Modules (PSDM) to improve the obstacle detection system. While this TSB is for the sliding doors, not the front doors, it shows that module software updates are a common repair strategy for these vehicles.
- TSB 23-015-17: Addresses an issue on some 2017 Pacificas where the power sliding door may not stay open on an incline, requiring a repair to the latch cables.
- Firmware Glitches: Forum discussions and TSBs for other Chrysler models indicate that electronic modules can suffer from software glitches that can be resolved by disconnecting the battery for several minutes to reset the modules or by having a dealer apply a software update.
Warning: The information in this article applies specifically to the front passenger door control module. Issues with the power sliding doors are often caused by different components, such as the Power Sliding Door Module (PSDM), wiring harnesses in the door track, or latch assemblies.
Programming and Calibration: The Most Important Step
Yes, a replacement Door Control Module must be programmed to the vehicle after installation. This is not a plug-and-play part. The programming process, often called a "Proxy Configuration Alignment" or "Proxy Align," is required for the new module to be recognized by the vehicle's Body Control Module (BCM) and other computers on the network.
Without proper programming, the module will not function correctly, if at all. The vehicle needs to know the specific options it's equipped with, such as power-folding mirrors, and associate the new module with the vehicle's unique Vehicle Identification Number (VIN).
Who Can Program the Module?
- Chrysler/Dodge/Jeep/Ram Dealers: A dealership is the most reliable option, as they have the proprietary wiTECH scan tool required for the procedure.
- Qualified Independent Shops: Many independent repair shops now have high-end scan tools (like Autel or Snap-on) and software subscriptions that allow them to perform a Proxy Alignment on FCA vehicles.
- Advanced DIYers: It is possible for a DIY mechanic to perform the programming using software like AlfaOBD paired with a compatible OBD2 interface and a security gateway bypass module. However, this requires technical knowledge and carries the risk of causing other system issues if done incorrectly.
Pro Tip: After physical installation, the power window may need to be calibrated. This is often done by running the window all the way down and holding the switch for a few seconds, then running it all the way up and holding the switch again. This teaches the module the upper and lower limits of the window travel.
Buying a Used Door Control Module for Your 2017-2019 Pacifica
A used OEM module is an excellent, cost-effective alternative to a new part. Since these modules are primarily electronic, physical wear is not a major concern, but compatibility and condition are critical.
The Power-Folding Mirror Compatibility Trap
This is the single most important factor when buying a used module. The initial warnings are correct: you must use a module from a vehicle equipped with the same power mirror options as yours.
- The module for vehicles with power-folding mirrors is physically and electronically different from the one for vehicles with standard power mirrors.
- Installing the wrong type of module will result in the mirror functions not working, and it may not program correctly.
- Always verify the features of the donor vehicle or match the OEM part number exactly.
Matching Part Numbers
The provided part numbers represent several supersession chains. For example, 68243315AA was likely replaced by 68243315AB, then AC, and finally AD. When buying used, it is always best to get the latest version available (the one with the highest letter suffix) as it will contain the most recent hardware and firmware updates. The key is to match the base number (e.g., 68245458) and ensure it is for the correct side (Right/Passenger) and mirror option.
Physical Inspection
When you receive the used module, inspect it carefully:
- Connector Pins: Look for any signs of green or white corrosion, which indicates water damage. All pins should be straight and clean.
- Casing: Check for cracks, water stains, or signs that the case has been opened.
- Part Number Sticker: Ensure the sticker is legible and matches the part you ordered.

Frequently Asked Questions (FAQ)
Does this module absolutely have to be programmed by a dealer?
No, but it does need to be programmed. While a dealer is a guaranteed option, many well-equipped independent shops can perform the required Proxy Alignment. Advanced DIYers can also do it with tools like AlfaOBD, but this is not recommended for beginners. A non-programmed module will not work correctly.
Can I use a module from a Pacifica that didn't have power-folding mirrors?
No. The module's hardware and software are specific to the options on the vehicle. You must install a module that matches your vehicle's original equipment, specifically the power-folding mirror option. Using the wrong one will lead to failed functions and programming issues.
My passenger window and lock stopped working. Is it definitely the door module?
Not necessarily. Always check the simple things first. Check the fuses related to the door modules and BCM. Also, inspect the wiring harness that passes between the door and the vehicle body for any breaks or pinched wires, as this is a common failure point on all vehicles. A diagnostic scan is the best way to confirm if the module itself is the source of the fault.
What tools are needed to replace the door control module?
You will need basic hand tools to remove the door panel, such as a trim removal tool kit, a Phillips head screwdriver, and a socket set (likely 7mm and 10mm). The module itself is typically held in place by a few small bolts or clips. The most important 'tool' is access to a diagnostic scanner capable of performing the Proxy Alignment after installation.
