Try to manually do it with your key on the outside if that works then you have some type of jam in the back and doesn't allow the electronic mecinishim to work. If it doesn't work then take off the door panels by removing the two screws and all connecting wires then look and see if anything is in the way or if it is even properly connected you may also want to check your fuses to see if it blew. if you have any questions go to the links i have provided.
