sierra central locking

[andyhib1]

Hi, I've just changed the drivers door on my 91 sierra xr 4x4 and have upset the central locking, I put the originl wiring loom,lock and motor in the new door but now it is completly dead, i checked all the fuses and their all good and also the fuses in the passenger footwell with the bank of relays so I'm a bit lost, maybe the relay for the C/Locking has been damaged but it is completely dead, even the interior lights don't work and i read that they are on the same circuit. The electric mirrors were also dead so i run a line direct from the battery and they worked so I've upset something but what i don't know, any advice would be much appreciated
