Hi I have a mk4 ibiza cupra and the central locking doesn't work on it anymore. I can lock the drivers door and boot manually but the passenger door can't be locked. I have checked the fuses. Stripped down the drivers door and checked wiring lock and switch. Thought I found the problem when the door plug was corroded. Cleaned it up but no difference. Does anyone have any ideas or similar problem. Any help would be appreciated.
