roll down the window and pull off the wether strips off you may now be able to see the rod from the outside handle that goes to the latch see if you squeeze your hand inside to move the rod or put some thing in there to operate the rod. if that don't work you may have to bust the door card off and open it from inside i had to do this with my mates nissan pulsar and managed to pull the door card off from the top with out causing that much damage. failing that fill in the door handles put some 3 door front seats in it happy day it's now a 3 door!!!!!!!!
