Why can I hear my air suspension system when my truck is not on & runi
Why can I hear my air suspension system when truck is not running like it lifts or drops when it’s off and sitting still and had been not running for hours I just so happen to be in my garage and heard it . I haven’t had any suspension problems but I did see suspension failure light a day or so ago but it when off and didn’t come back on I haven’t had truck long what could be the problem. Truck still lifts it’s not sitting on tires but I think something is going bad some part or sensor any thoughts or suggestions????
