This has happened on my car once before in the past (shortly after i got it). The passenger door wont open from the inside of the car, but it will however open from the outside as normal. This seems to have happened since i used the internal switch on the drivers door that locks the car from inside (anti hijack switch?). Any ideas whats causing this? Do i need to take the door apart & have a look and see for myself? Any helpfull advice/tips on this matter greatly recieved. Cheers, Pete. P.S. I said it did it once before. After very little time it sorted itself out (amazing/impossible i know, but it did). It has now been like this since new years eve.
