* Latch is not engaging: The most common reason. The latch mechanism on either the hatch or the vehicle body might be broken, misaligned, or obstructed by debris. Inspect the latch itself and the surrounding area for any damage or interference. Check if the latch is properly aligned and making complete contact.
* Liftgate cable or linkage is broken: The cable that raises and lowers the hatch could be snapped or damaged, preventing it from latching properly. This often results in the hatch not staying closed or not opening at all.
* Electrical issues: If your Durango has a power liftgate, there could be a problem with the motor, wiring, or the liftgate control switch. Check the fuse related to the liftgate and test the switch.
* Safety switch malfunction: Some vehicles have safety switches that prevent the liftgate from closing if something is obstructing it. A faulty switch might keep the hatch open even when nothing's in the way.
* Damaged or misaligned striker: The striker plate (the metal piece on the vehicle body that the hatch latch engages with) might be bent, damaged, or not aligned properly.
* Hydraulic lift supports (struts): If your Durango uses hydraulic struts to support the weight of the liftgate, they could be leaking or broken. Weak or failing struts could prevent the hatch from latching fully.
Troubleshooting Steps:
1. Visual Inspection: Carefully examine the latch mechanism, cables, striker plate, and liftgate itself for any visible damage.
2. Manual Operation (if applicable): If your liftgate is powered, try to close it manually (most liftgates have some form of manual override). This will help you determine if the problem is electrical or mechanical.
3. Check for Obstructions: Ensure nothing is blocking the latch from engaging.
4. Lubrication: Lightly lubricate the latch mechanism and moving parts. Use a silicone-based lubricant.
5. Fuse Check (if applicable): If the liftgate is power-operated, check the relevant fuse in the fuse box.
If you've checked all these things and the problem persists, it's best to consult a mechanic. They have the tools and expertise to diagnose the problem accurately and repair the rear hatch.
