The following information tells you how to access your vehicle's relay and fuse center for checking and replacing fuses.
Using a screwdriver, remove the relay and fuse center cover by lightly expanding the spring clips on each side of the cover. Replace the 30 amp mini fuse with a 30 amp (or less, as required by the added electrical accessory) mini fuse. Use a fuse puller, if your vehicle has one. Replace a relay with a GM Part No. 12088592 relay, or equivalent.
After servicing the panel, reinstall the relay center cover by pressing the cover back on. Make sure the larger slot in the cover faces the driver's side. Reinstall the fascia cover on the instrument panel. Make sure the relief slot faces the bottom of the instrument panel.
Additional power and ground fuses (40 amps) are located under the hood, next to the battery.
