[Smootholdboy]

Hi
After the snow melted i decided my boxster deserved a well earned spin, when i arrived back home my wife could'nt open the passenger door. The window does the usual 1 cm drop but thats it, its as if there is a child look on as it opens from the outside but accourding to the manual it dosent have a child lock. Any info would be much appreciated.
