What to Do When the Ford Mondeo's Tail Lights Remain On After Locking the Car?

First, remove the protective panel, which is the floor panel located above the brake, clutch, and accelerator pedals. Identify the brake light switch, which is a twist-lock type. Turn it counterclockwise to remove it. Install the new brake light switch by inserting it into the twist-lock socket. Reinstall the protective panel following the reverse order of removal. After replacement, test the brake system to ensure the brake lights are functioning properly.
Hey, I just helped my neighbor with this issue recently. It's really annoying when the Ford Mondeo's tail lights don't turn off after locking the car. Usually, it's because the doors or trunk aren't properly closed, and the signal isn't being transmitted correctly. First, I'll try gently closing all the doors and trunk again to make sure they're locked properly. It could also be a fault in the lighting module or a short circuit in the wiring. When fixing it yourself, open the driver's side fuse box, locate the tail light fuse (most Ford manuals have diagrams), and check if it's blown—replacing a simple 10A fuse might do the trick. But be aware that leaving the lights on all night will drain the battery quickly, and you might not be able to start the car the next day, so it's best not to park for too long or keep jumper cables handy just in case. For safety, take it to a repair shop to check the system—they can quickly diagnose the issue with a computer to avoid accidents. In daily use, after pressing the lock button, don't walk away immediately; wait a few seconds to see if the lights turn off.
