What to Do If the Cruze Trunk Switch Fails?
3 Answers
Solutions for a malfunctioning Cruze trunk switch: If the trunk can be opened using the remote control, it indicates that the trunk switch is damaged. If the remote control also fails to open it, the lock block may be damaged. There is an emergency escape switch above the trunk lock; pulling it down can open the trunk. Below are the symptoms of a trunk that won't open: 1. The Cruze trunk door is operated remotely. When using the remote to open the door, remember to long-press the trunk unlock button to open it. Of course, when pressing the trunk unlock button, the central locking system should also unlock. If the remote can open it but the trunk still won't open, it may be due to rainwater entering the trunk switch area causing corrosion, which is a relatively common issue. The only solution is replacement, which can be done at a 4S shop. 2. If neither the remote nor manual methods work, it could be due to a damaged trunk lock block, requiring replacement. Additionally, there is a master switch for the trunk lock above the lock block; it's also important to check if the trunk's failure to open is caused by the master switch being turned off.
My Chevrolet Cruze's trunk switch suddenly stopped working. I tried to inspect it myself and found that the fuse might be the issue. Typically, the trunk fuse is located in the fuse box in the engine compartment, and its position can be referenced in the owner's manual. I pulled it out and saw that it was indeed blown, so I spent a few bucks to buy a new one and replaced it to test. If it still doesn’t work, the switch button might be broken or there could be a short circuit in the wiring. I opened the trunk lid myself and used a multimeter to check the voltage, seeing if the button contacts were oxidized or worn out. Sometimes, rainwater seeping in can also cause wiring corrosion, which needs to be cleaned up. If the trunk can still be opened manually with the key, the problem isn’t too serious and can be temporarily fixed. But remember, don’t force the switch open to avoid damaging other components. Regular maintenance of the electrical system can prevent such issues. Replacing fuses or switches isn’t expensive, and doing it yourself saves money and builds skills.
As someone who frequently repairs cars, I recommend starting with simple steps: First, check if the trunk fuse is blown. Its location is usually in the footwell fuse box in the cabin, labeled for the trunk circuit. If it's blown, replace it with a new one—it's inexpensive. If the fuse is fine, test the switch button for poor contact. The normally open design of the button makes it prone to aging; use a multimeter to check conductivity. Next, inspect the wiring, as the lines near the trunk hinge often wear out or short-circuit, leading to malfunction. The relay could also be faulty—try replacing it near the fuse box. If the issue persists, consider mechanical failure in the lock assembly or interference with the remote signal. For Cruze models, the trunk switch connects to the body control module, and module damage requires professional diagnosis. Early inspection prevents the trunk from accidentally opening while driving—safety first. It's advisable to visit a repair shop for a comprehensive check to avoid disrupting daily use.
