If I recall...you need to get yourself into the rear compartment and remove the panel from the tailgate structure with plastic trim levers sufficiently to get access to the latch mechanism . Once you've done that, you can manipulate the rods which connect the solenoid to the latches on each side of the tail gate (pull them simultaneously towards the centre)...they may have become dislodged...
I hope my memory is better than my forgettery!
cheers
