    Rear hatch won’t unlock or open

    Rear hatch won’t unlock. When I cycle the door locks, I can hear the rear hatch mechanism locking, but nothing happens when unlocking. There’s no way to open it with a key. Both the rear glass and the rear hatch remain locked. Is there a secret release somewhere? I guess I could attempt to...

    Unfortunately broke 3 of the 8 fuel injector clips. 5 released without issues. The other 3 broke when I was releasing the injector plug. They still plug into the injector but they can now be pulled off by just tugging on the wire. Is this a big deal? Do I need to replace the entire injector...
