Whether you plug in a key, push a button on the dash or start it remotely, the ignition switch is arguably the most important part of your GMC Yukon XL 1500 because it starts and stops it. Switches for the ignition and for all your vehicle systems are available at the lowest prices from StockWiseAuto.com.
A failing switch can also affect other electrical systems, which it is meant to activate upon startup. If the ignition connection is not made, these other systems can also malfunction. After checking the fuse and battery, move on to the ignition switch, and replace it if needed. Your best price on switches is always on StockWiseAuto.com.
