So my girlfriend and I recently purchased a 2004 Trailblazer. Nothing really wrong with it, but she brought it to my attention that underneath the passenger seat, there's a wire that's not plugged in (clearly visible when looking under the seat) I couldn't find where it plugged into and so I checked the driver side and learned that it's unplugged there as well. Was wondering if I anybody might know what it is or maybe the reason they're unplugged? Because every electronic function on the seats work which is what's slightly confusing. 🤔 P.S it won't let me add any photos on my mobile so I'll update with pictures when I get home.
