Ibiza closure

Hello good. I have a small problem with the lock of my Seat Ibiza TDI. It does not detect the opening of the driver's door. Sensor, Center that is the question

You must dismant

The cables are in perfect condition, the only ones are cut are those of the LED that carries at the door. The diagnosis of the machine is that they are failing the two locks that does not fit because only in one (the driver) is the problem. As for the sensor is inside the closing package and it is armored and it cannot be disassembled and I do not have the data to be able to check them with the polyimeter

Go in the wiring and test the continuity with the open lock and then with the lock closed always knowing what are the cables of the Singor previously, it will not be that I disconnect some ground cable from the layout of the doors
check.

YAP, but well I have the problem when disassembling the door to be able to verify that that I have no way. I don't know the inner sheet. Anyway, tomorrow I will try and I have bought the complete scrapping lock. That is why I will do with the car manual but I think that the Leon explodes helps me to disassemble the sheet that carries the interior
