I have a 2007 Chevrolet Silverado Classic 1500. The check Engine light is on and i took it to auto zone and their diagnostic scanner did not power up when they plugged it in. The guy said it may be a blown fuse. Ive had 3 people tell me 3 different things. 1 That i need a CAN Scanner, 2. That i need power at the fuse and ground, and 3 that there is a fuse out. i dont know what to do, is this normal?
