2009 Chevy Express Low beams not working
High beams work fine but low beams don't work even with new bulb. I read somewhere about a relay, where is the location? also, what else can it be?

The Chevrolet Express Cargo is a full-size van available in half-, three-quarter and one-ton versions - 1500, 2500, and 3500, respectively. With three available engines, two drivetrains, and two wheelbase lengths across six trims, the Express Cargo provides a large range of configurations depending on your application. As opposed to the Express Passenger van, the Cargo has replaced the side and rear windows with metal panels, or in versions not equipped with the optional driver’s side 60/40 doors, optional access panels.
Available engines, all mated to a four-speed automatic, include a 4.3-liter, 195-hp V6; a 5.3-liter, 295-hp, E85-friendly V8; and a 6.6-liter 250-hp, turbodiesel V8. Maximum towing capacity is 5,900 lbs for the 4.3, 6,500 lbs for the 5.3, and 10,000 lbs for the 6.6. While EPA estimates have yet to be released for the 6.6, the 4.3 achieves 15/20 mpg, and the 5.3 manages 10/12.
While a carryover year, the Express Cargo saw some much needed additions and changes in 2008, including a low-tire pressure monitoring system and an expanded info display that notifies the driver of general vehicle status and maintenance scheduling. This was part of the new interior that the Express received last year as well.
Configuration options vary across platforms, with 1500’s available in the standard wheelbase of 135 inches, while the 2500 and 3500’s are additionally available in the extended, 155-inch wheelbase. Additionally, 1500s are available with all-wheel drive.
