You can try directly replacing the spiral cable. It could also be that the buttons are damaged, causing them to malfunction, in which case the steering wheel button circuit board needs to be replaced. The exact cause and solution can only be determined by a professional inspection at a repair shop. Below are some methods to address unresponsive multifunction steering wheel buttons: 1. Check if it's a functional failure. Currently, most multifunction steering wheel buttons control features like multimedia volume adjustment, Bluetooth phone calls, and multimedia track selection. Try pressing these multimedia buttons on the center console to see if they are also unresponsive. 2. It's recommended to check if the steering wheel control module is faulty. 3. The multifunction steering wheel buttons are connected via the airbag slip ring circuit. The vehicle's electronic control unit stores corresponding fault codes. It's advisable to have a professional technician diagnose and resolve the issue based on the fault information.
I just experienced unresponsive multifunction steering wheel buttons. First thought was dirt buildup causing contact adhesion or oxidation. I tried gently cleaning button crevices with alcohol swabs - removing dust helped significantly. If cleaning doesn't work, check wiring harness connectors under the steering wheel; prolonged driving vibrations may loosen connections. I personally reseated the plugs to ensure tightness. Low battery voltage could also affect button power supply - inspect relevant fuses in the fuse box and replace if blown. Worn buttons or module failure require part replacement - visit dealership for diagnostic scanning and software reset. Safety note: Malfunctioning buttons affecting volume or cruise control shouldn't be addressed while driving - pull over safely for troubleshooting or seek professional assistance.
