That is a good question, you do know theres a lever you need to pull to open the hatch right? Not the hatch release lever in the car; theres a lever just underneath the grip provision on the hatch itself.
The change was made so you could open the hatch from outside, without having to go into the cabin and pull the release(when the doors are unlocked).
Shit my old 96's hatch would just spring open after I pulled the release cable. But not the 98+ they've got the lever in the hatch.
INot to jack, but does anyone know how to lock your doors(all including hatch) with the switch on the hatch? Because I've done it a dozen times but couldn't ever figure out how it drove me insane!!
