Drivers of the 2004 Chevy Silverado have reported common ignition switch issues with this early 2000's model truck. Some signs of the problem include warning lights flickering, stalling at idle, and difficulty starting the vehicle. When using an OBD scanner, you may see a P1682 error code. While the repair process is not overly complicated, it does involve removing and replacing the ignition switch. Over time, the contacts inside the switch wear out, leading to temporary loss of voltage and stalling. To prevent this issue, consider using only one key on your key ring to reduce strain on the switch caused by heavy keys.
