Central locking help

[e30Alex]

Hi guys, my central locking has suddenly died. Was working perfectly now nothing. I can here the relay click when I manually press the drivers door pin inside the car. Any suggestions before I start ripping it apart? Fyi dosent work from any door lock now inc boot or interior pins. Thanks in advance Alex

First thing to do with central locking, in full working order, or not, is to perform the "red/black wire modification".
