Sorry if this ha been asked before, but i cant find the answer.

I have just brought a santa fe 2 56 reg and don't know any of the history.

I am looking for a wiring diagram for the central locking system as i have one rear lock that tries to lock with little movement (drivers side) and the other rear lock locks ok if left for a while.(passenger side)

I have downloaded the Haynes manual but it does not reflect the wires on my car. I have 5 wires on the RHS door (pink, orange, black blue and green i think) and having stripped the door apart it looks like that the door lock actuator on the rear drivers side has been replaced with a scrap yard part in the past.

Before i go buying a new part i would really like to test the electrics for any breaks if possible.

Thanks for your help in advance
