My central locking does`nt seem to open my front passenger door.

When I use the fob I must open the front pass door with the door handle lock inside the car.

When I want to lock the doors they dont all lock or less I have locked the front passanger lock from inside first.

when it is locked from the inside I can lock the car using the key fob and the lights will flash.

Anything I shoud be checking infuse box area?


Thanks
