Hi all Firstly thanks for the responses. I've checked the cabling and although there is some wear and tear I'm leaning towards the fuse or the control unit for the central locking. Having checked the handbook I'm confused on which fuse number would be linked to the central locking plus should it not be the fuse where the control unity is as it is not under the passenger seat. Hopefully you guys and gals could advise Much apprecated MK1 Zetec 2001 X Reg 1-9tdi
