    I’ll tell you up front I don’t know anything about Volvo. But most trucks operate those items with air. And your problem would be a valve mounted on your secondary air tank that operates these accessories which is probably stuck.

    But Volvo could be different.

    I think it’s electrical. Because the indicator light isn’t showing it has been selected

    F16 is diff lock fuse
    F23 is air suspension

    F01-F40 fuses are in the front facing fuse panel F40 and up are in top fuse panel.
