From the shop
Fuses and relays for the body and accessory circuits live in this box, standalone rather than folded into a switched module. When something acts up, it's usually one of those circuits going dead or getting flaky rather than one obvious failed part, so this is often the first thing worth checking. Tested functional. All relays and fuses checked. Cleaned. Mounts front, left, driver side. No programming required. Fits 2016–2019 Chevrolet Silverado 1500, Silverado 2500 and Silverado 3500, GMC Sierra 1500, Sierra 2500 and Sierra 3500. Part numbers: 84075776, interchange 84303175, 84075777, 84075778.
