To fix a broken temperature gauge on a 1999 Cabriolet, start by checking the fuses to ensure they are intact. Next, inspect the wiring and connections to the gauge for any damage or corrosion. If those are in good condition, test the temperature sending unit (sensor) for proper functionality and replace it if necessary. Finally, if all else checks out, consider replacing the gauge itself or consulting a professional for further diagnosis.
