Hi, got this car yesterday and the rear sliding doors won't open from the inside.  They will close from the inside but won't open. 

 

My my first thought was child locks, but I can't seem to find anything about this cars child locks.  On the door there is a little symbol of a child lock with an arrow, but I can't seem to find the little thing to activate or deactivate it. The round hole where I would expect the lever for child locks there is just a black piece of plastic.

 

any ideas? Thanks.  

Here is a photo, where I would expect to find the child lock switch there is just black plastic.  

Ok sorted the rear window lock button also does the doors.  Of course.

Hi Joelwool,

Don't know about the 2014 GCmax but on my 2016, the window lock button on the drivers door as well as locking the windows, also activates the child locks on the rear doors. This not the door lock button which is higher up the door but at the front of the arm rest with the electric window buttons.
