Mitsubishi Trunk Latch Replacement Guide
In this guide, we will be showing how to remove the trunk latch on a 2019 Mitsubishi Outlander and install a new one.
If your Mitsuibshi trunk won't open, first inspect the trunk release and also the cable that runs from the driver's seat to the trunk. If your Mitsubishi has a button to relase the trunk, then you need to inspect the button and the electrical wires that run from the button to the trunk latch. You can use a digital multimeter to test for power at the trunk latch when trunk release button is pressed. If there is power but the trunk latch won't realse, replace the trunk latch.
This repair will fix faulty trunk latches not closing or operating properly. It is common for trunk latch actuator motors to go bad or for the latches to get misaligned or damaged. If these problems occur, follow this guide to remove and replace the trunk latch on your vehicle.
What you will need
- Trunk latch
- It may also be called lock w/ actuator motor assembly.
- Open the trunk, remove the plastic trim on the inside of the trunk. Using a wedge trim tool, carefully pry down to pop it off. The trim is held in by plastic retainers around the perimeter of it, pull each part of the trim until the retainers pop out of the trunk. Set the trim piece aside.
- After the trim is removed, a hole is exposed in the trunk's sheet metal to get to the trunk latch. The trunk latch has an electrical connector going into it that needs to be unplugged. Find the connector and push down on the tab of the connector and pull apart to release the connector from one another.
- Next, remove the three bolts holding the trunk latch in. Then, the trunk latch can be removed through the hole in the sheet metal.
- Finally, install the new trunk latch with the three bolts. Don't forget to plug in the electrical connector and reinstall the trim the same way it came off.
How can I fix my trunk latch that won't close?
The odds are that the trunk latch actuator motor or latching mechanism is stuck or malfunctioning. Use this guide to replace the whole unit to fix the problem. Also, check to make sure the trunk striker latch is still intact and aligned properly on the bottom of the trunk. Some may need to adjust for proper alignment.
My trunk won't open; how can I fix my trunk latch that won't open?
If the trunk won't open, the trunk latch is stuck. This can happen when the mechanism wears out over time, the grease in the latch dries out, and latches rust. Crawl through the back of the vehicle and use a flathead screwdriver and pry in between the locking part of the latch and the striker.
If there is an emergency trunk release, pull it to help release the latch. Once the trunk is open, remove and replace the trunk latch with a new one.
