Did anyone identify what is causing this issue? This issue just happened to me. Headlights don't work on low beam or high beams, the fuse is good in spot #59 in fuse box under hood. Both headlights were replaced in the last year because they were so hard to see with. I don't think I received much improvement. The only way I can see is using fog lights. No service departments are open. I don't know about anyone else, but this is a huge safety issue that needs to be addressed by GM.
