My lights won't switch to bright

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Ah, the mysterious case of the stubborn headlights and the rebellious backup camera, all wrapped up in a Cadillac CTS drama. When your lights refuse to switch from dim to bright, it's usually a sign that the multifunction switch (the stalk on your steering column) is playing hard to get. This switch controls the high beams and can wear out over time. Given that your backup camera is also on strike, we might be dealing with an electrical gremlin. Check the fuses related to the lighting and the backup camera. Your car's manual should point you to the right ones. It could be that a single fuse or relay is causing the dual mischief. If everything looks good on the fuse front, then it might be a wiring issue. Inspect the wiring harness for any loose connections or damage, particularly around the multifunction switch and the backup camera system. If you're not keen on chasing electrical gremlins, a visit to your friendly neighborhood auto tech might be the way to go. Think of them as the detectives in your favorite mystery series, ready to crack the case and get your CTS back to its bright and shiny self.
