SM25T Posted September 7, 2023 Share Posted September 7, 2023 That won't help if something is shorting under there. Have to find and sort that first. Often the lighting supply to the switches with illumination, as the connectors are very close to the aluminium dash panel. Link to comment Share on other sites More sharing options...
