On my way home and parking brake light goes on and off. Shortly later abs light comes on along with several lights. Along with battery light. I was thinking it was charging issue but it never said anything on message board. Continued to drive truck expecting it to cut off. But never did lose power. Got home and checked under hood fuses and cab fuses.. all fuses were good. Truck is still cranking fine and running. But abs light is still on and air bag and battery lights on. Fan motor is working but ac not working. And dome light inside of truck not working. I didn't think it was alternator but I'm not sure. Thanks

 

The 2007 Silverado Classic is the GMT800 platform and I'd refer you to that generation of trucks in the forum.
