Where is the spare tire lowering handle located on a 1999 gmc sierra?

The spare tire lowering handle on a 1999 GMC Sierra is typically located inside the rear passenger side of the truck, usually near the bottom of the sidewall or behind the rear seat. It might be a small, lever-like handle, or a rope/strap. You'll likely have to reach behind some upholstery or cargo area panels to find it. There isn't a universally consistent spot across all trims, so some careful searching is often needed.
