You press the button on your 2021 Chrysler Voyager expecting the power liftgate to swing open, but nothing happens. Or maybe it starts to open and stops partway. A non-functioning power liftgate isn't just an inconvenience—when you're loading groceries or luggage with hands full, it becomes a significant frustration. Here's how to diagnose and resolve the problem.
How the Power Liftgate Works
The power liftgate system uses electric struts (actuators) on each side of the liftgate, a latch mechanism at the top, and a control module that coordinates operation. Sensors detect obstacles, and the system responds to inputs from the key fob, interior buttons, and optional foot-kick sensor.
Common Symptoms
- Liftgate doesn't respond to any button
- Liftgate beeps but doesn't move
- Opens partially then stops or reverses
- Makes grinding or clicking noise without moving
- Opens but won't close (or vice versa)
- Very slow operation
Common Causes
Latch Malfunction
The power latch at the top of the liftgate opening must release before the struts can push the gate open. A failed or stuck latch prevents initial movement.
Strut Failure
The electric struts do the heavy lifting. When one or both fail, the gate may not open, may open slowly, or may not stay up. Symptoms often start as slow operation before complete failure.
Pinch Strip Triggered
The rubber strip around the liftgate edge detects obstacles. If this strip is damaged, disconnected, or constantly triggered, the system stops movement as a safety measure.
Wiring Problems
The wiring in the liftgate area flexes repeatedly with each open/close cycle. This can cause wire fatigue, breaks, or loose connections over time.
Module Issues
The liftgate control module can experience software glitches or hardware failures affecting system operation.
Key Fob Battery
If the liftgate only fails to respond to the key fob, a weak key fob battery may be the simple culprit.
Diagnostic Steps
- Try all activation methods: Test key fob button, interior button, and manual liftgate handle. If only one method fails, the issue is input-related.
- Listen for latch operation: When pressing the button, can you hear the latch attempting to release? No sound suggests latch or electrical issue.
- Check for obstructions: Ensure nothing is caught in the liftgate seal or blocking the path of travel.
- Inspect pinch strip: Look for damage to the rubber strip around the liftgate edge.
- Manual release: Use the manual release to open the gate and observe if struts are holding properly.
Manual Override
Most Voyagers have a manual release inside the liftgate:
- Access the interior panel of the liftgate
- Locate the manual release lever or cable
- Pull to release the latch
- Manually lift the gate (it will be heavy without power assist)
This gets you access while awaiting repair.
