I have a 2000 blazer ls 4x4 4 door and cant get the rear window on the hatch to open or the buttons to lock the doors to work either. it has the full hatch where it opens from the bottom and has the separate window that can open when the hatch is down. the truck will lock and unlock with the remote but the buttons do nothing and the two buttons for the rear window are dead and if I hit them there is no noise coming from the back rear hatch. im stumped, ive checked the fuses and still nothing. in need of some help please.
