2008-2020 Grand Caravan & Town & Country Liftgate Latch Motor: Why It Won't Close and How to Fix It

Symptoms of a Failing Liftgate Latch Motor

When the power liftgate latch motor fails, it can be frustrating. The gate might seem to close, but it won't secure properly. Here are the most common signs that your latch motor is the problem:

• Liftgate Closes but Won't Latch: The gate lowers completely but fails to pull itself tight. It may bounce back up slightly, leaving a gap.
• 'Gate Ajar' Warning Light: The dashboard displays a warning that the rear hatch is open, even if it appears closed.
• Gate Reverses After Closing: The liftgate touches the striker, then immediately re-opens. The system's safety feature interprets the failed latch as an obstruction.
• Grinding or Clicking from Inside the Liftgate: When the gate attempts to latch, you may hear grinding or rapid clicking sounds from the latch area, indicating broken internal gears.
• Tailgate Will Not Lock: The electronic locking portion of the actuator may fail, preventing the liftgate from locking with the key fob or door switches, even if it's manually closed.
• Complete Failure: The latch makes no sound and does not attempt to pull the door shut.

Definitive Diagnosis: Is It Really the Latch?

Before you buy a new latch, follow these steps. On these minivans, other issues can mimic a failed latch motor. The most common culprit is not the motor itself, but the wiring that powers it.

Step 1: Inspect for Broken Wires (The #1 Most Common Cause)

The wires that power the latch run from the vehicle's body into the liftgate through a flexible rubber boot. After years of opening and closing, these wires can fatigue and break. This is the most frequent cause of latch failure.

1. Open the liftgate.
2. Locate the rubber wire harness boot, typically on the top left side, connecting the body to the gate.
3. Pull the boot back from both the body and the liftgate to expose the wires inside.
4. Carefully inspect each wire for breaks, cracks in the insulation, or frayed copper strands. A broken wire here will cause a complete loss of power to the latch.

Step 2: Check the Fuses

The power liftgate system is protected by a fuse, often a 30-amp fuse located in the main fuse box (Totally Integrated Power Module) under the hood. Consult your owner's manual for the exact location and check to see if it's blown.

Step 3: Check for an 'Out-of-Sync' Latch

Sometimes, the latch can get manually moved to the 'closed' position while the liftgate is open. The system then gets confused and thinks there is an obstruction when it tries to close. You can often reset this manually.

1. With the liftgate open, look at the latch mechanism.
2. If the hook is in the closed position, use a screwdriver to carefully push the spring-loaded catch and rotate the hook back to the open position.

3. Try operating the power liftgate again.

Step 4: Inspect the Power Liftgate Module (PLGM)

The PLGM is the brain of the system. On the Town & Country and Grand Caravan, it's located in the rear cargo area on the driver's side, behind the panel where the jack is stored. On other FCA vehicles, this module is known to be susceptible to water damage, which causes corrosion on the connectors. Unplug the connectors and check for any green or white crusty buildup. If corrosion is present, the module or its connector may be the issue.

Buying a Used Trunk Lid Pull Down Motor

If you've ruled out wiring, fuses, and sync issues, replacing the latch is the next step. Given the high cost of a new OEM part, a used latch from a reputable recycler is an excellent, cost-effective option.

• Huge Cost Savings: A used OEM latch can often be purchased for a small fraction of the new OEM price, which can be over $600.
• OEM Quality and Fit: A used genuine Mopar part guarantees perfect fitment and the same quality as the original part, unlike some aftermarket alternatives which may have functional differences.
• No Programming Needed: This part is plug-and-play. There is no need for dealer programming or special calibration, making it a perfect DIY-friendly replacement.
• What to Inspect: When buying used, visually inspect the part for any cracks in the plastic housing. Ensure the electrical connector pins are clean and not corroded. If possible, choose a part from a vehicle with lower mileage.

Known Issues, TSBs, and Recalls

While there are no major recalls specifically for the latch motor on these vans, there are related service actions to be aware of:

• NHTSA 12V-191 (Chrysler Recall M17): This recall affected a small number of 2012 Town & Country and Grand Caravan models. The issue was with the right-side pinch sensor, which could require excessive force to stop the gate during closing, increasing injury risk. It did not involve the latch motor itself.
• Broken Wire Harness: While not an official recall, broken wires in the liftgate harness are a widely documented, common failure point that directly affects the latch motor's operation.

Replacement Overview

Replacing the liftgate latch is a manageable job for a DIYer with basic tools. The difficulty is about 2 out of 5.

1. Open the Liftgate: If it's stuck closed, you must climb inside the vehicle. Remove the small access panel in the center of the interior liftgate trim and use a screwdriver to move the manual release lever.
2. Remove the Interior Trim Panel: Use plastic trim removal tools to carefully pry off the large plastic panel on the inside of the liftgate. Start at the bottom and work your way around.
3. Unbolt the Latch: The latch assembly is held in place by three T30 Torx bolts.
4. Disconnect and Replace: Disconnect the electrical connector and any release cables attached to the old latch. Install the new latch and reconnect everything.
5. Test: Before reinstalling the trim panel, test the power liftgate function to ensure the new latch is working correctly.
