does anyone have a wiring diagram? there are 3 wires in the wiring to the power unit in the hatch (i have the cover off of the hatch) - there is a black, a white/green and a black/orange. assuming that the black is the ground - i have 12V power from the black/orange across the black all of the time - is this right or is there a short? there is nothing across the white/green and black.

there is no change across the wires when you hit the dash button or the key fob

thanks, peter

You need 12V across the white/green and black to actuate the hatchlock motor.

1) Check the 20A fuse for the lock system. The fuse is on the BACK of the passenger compartment fuse panel.
2) Check the black to make sure it's a good ground.
3) Check for 12V across the green when the button is pushed. If you get power, it's the lock mechansm.

4)Disconnect the harness from the dash button and test the switch to make sure it's good.
5)The next part gets more in-depth -- you'd have to locate the central lock module, and check the white/green for power there.
