Eletrical Issues

[eggiemk1]

Hi, i have a W reg KA which i bought recently, it was cheap so expected some issues but this one has got me proper stumped.

The boot release button next to the steering wheel didnt work, the motor works and i followed it all the way back to the switch unable to find an error. i went to my haynes manual to the wiring diagrams and have hence found that the car has central locking, this dosnt work (didnt even know it had central locking till i started fiddling about) and this is the reason the boot release wont work. but i cannot find a reason for it not to work. i have checked all the fuses and checked all the earths i can find. does any one have any ideas what could be up with it?

if any one has any ideas email me on eggiemk1@hotmail.com
