Last year I had the same issue on my 2016 Sierra. Every time I used the power slider, it would blow the fuse and periodically would drain my battery down. Working with the dealer, we traced it to a pinched wire in the center console. The dealer also believed pinched wire was causing the BCM to run for a diagnostic scan and draining the battery. The wire that was pinched, also fed the wireless charger and light inside the console. End result was replacement of the wire harness in the center console; no issues with the slider or dead battery in the past year.
