02 Mondeo 2.0 TDCI Ghia X Estate - Central Locking - BMush

Hi, I'm hoping someone can point me in the direction of where to start fault finding with this. I bought the car a week ano, two days later, passenger side front and back central locking stopped working. Yesterday, driver side rear stopped working. Drivers door and boot still work fine, but the rest are unresponsive. Any ideas where to start, i.e. which fuses to check, as there is no fuse diagram on glove box.

Also, anyone have any recommendations fopr air con check/regas in Liverpool/knowsley area?

this could be a faulty GEM unit which controls the central locking

or it could just be a short somewhere, I think you need it checked by an auto electrician..
