Right the next query....

Our "new" 3 door 1997 SE has central locking which currently only works from the passenger side so. and when locking from the passenger side the air pump can be heard running, and from the drivers door you can hear the air whistling behind the lock so......
Is this a common problem?
Is it just a case of a tube becoming disconnected, and is it just an easy push-on refit?
Can anyone guide me as to how to remove the interior door card [manual windows] any pictures of door card removal and or piccies of the door lock workings??
Thanks in advance once again

The to do list is slowly getting smaller
