My Chevy 2012 2500 hd cruise isn’t working. I hit button on steering wheel and no light comes on steering wheel or dash. I’ve only had truck about 2 months and didn’t notice cruise not working until now. I checked the fuse with manual diagram and it’s fine, so not the problem. I think steering switch just isn’t getting power. No light comes on dash showing cruise is on. Any recommendations on how to systematically troubleshoot this? Thanks
