Rear Tailgate 2008 Kluger Grande

[AnnC]

Hi all, I have replaced my dented tailgate with anothe Grande one from a wrecker, fitted up easily but locking and auto open/close dont work. 

Manually closing, it doesnt pull in automatically and lock, doesn't push in and lock and and push button above number plate doesnt work either. Auto open/close not not working as well. 

All electrics are connected and tried exchanging bottom lock mechanism with the original one but no go.

I know about the button next to glove box and having rear tailgate wondow closed.

Any ideas, suggestions or anyone had this problem?

Thank you
