How to Open the Trunk of a Citroen C-Quatre When It Won't Open?
3 Answers
Here are two methods to solve the issue of a Citroen C-Quatre trunk not opening: 1. Open the trunk from the outside. Open the driver's door, pull up the handbrake to prevent the car from rolling, pull the trunk switch located on the left side of the driver's leg area, and press the lock latch on the outside of the trunk. 2. Open the trunk from the rear door. Inside the rear door, there is a small mechanical switch next to the lock block; pulling it will open the trunk. After opening, check what caused the trunk not to open. You can adjust the relative position of the trunk lock and the lock hook and lubricate the lock hook. Focus on checking whether the door lock and the locked assembly are properly fitted, or apply some grease to the door lock block and lock post. Adjustment and lubrication should solve the problem.
I drove a Citroen C-Quatre for several years and had issues with the trunk not opening. Start by checking the simplest things first. The most common cause is a dead remote key battery—try replacing it with a new one. If that doesn’t work, inspect the keyhole for any stuck debris and gently pry it open with a screwdriver or spray some lubricant. The trunk lock linkage might be loose or rusted; look for the emergency release cable inside the car (usually behind the seats) and give it a pull—it might open. Also, check the trunk-related fuse in the fuse box to see if it’s blown; you can buy and replace it yourself. Problems often arise after rain or rough roads, so try a few times. If all else fails, avoid forcing it open to prevent body damage and take it to a professional repair shop as soon as possible.
As a Citroën owner, analyzing the structural causes of trunk malfunctions is essential. The locking system may be controlled by an electromagnetic switch or mechanical components. Check if the key signal is malfunctioning, and consider re-pairing or replacing the battery; inspect whether the trunk lid linkage is broken or corroded, and try manually pulling the release button; common circuit issues include blown fuses, so locate and inspect the fuse box under the dashboard. If the electromagnetic lock fails, it might be due to module damage or a software bug, requiring specialized equipment for diagnosis. Additionally, watch for trunk seal aging, water ingress, and lock core rusting—regular cleaning can prevent these issues.
