Ka Collection Electrical Faults, help!!

[Tyrannous]

Hey guys, I have a 00 reg Ka Collection and i bought it with no central locking or boot button working, i replaced i blown fuse which strangely made the problem worse, the boot button now works only when the passenger door is unlocked and the central locking only works in that door also (bit pointless). One last fault with this door problem is that when i open the passenger side door the Speakers turn off in the car, so if i am playing music it stops when the passengers open their door, other than this i have no more faults, any clues on what could be causing the problem? any help would be greatly appreciated. Thanks

check the wireing at the passenger door hinges for any damage or shorting.

Thanks for the info but im a bit of an idiot when it comes to cars, how do i safely remove the rubber tubing around the wires in the door hinge? Thanks :-)

they should should pull out of the door and the body.
