Hello I am having an unusaul problem with my Xsara I recently fixed the dodgy door grommet wires, someone was in before me and the work was quite bad, but the wires have been properly repaired, it got the drivers door window working again, and i have inspected the wires fully to ensure there are no cracks left. There was also a problem with the front passenger door, it closed mechanically speaking, but the instrument cluster and MFD kept showing it as being open, and it would intermittently change when the door was pushed or while driving along, i changed the part with one from a scrap car and it now registers as closed. But the remote central locking is still giving problems, i put a battery in the key, the key will unlock the car and make the lights flash, and it will unlock the boot. But it does not lock the car, when i press lock on the remote the car tries to lock, then instantly unlocks again, if i physically put the key into the door and lock it the doors centrally lock ok, and unlock, and if i sit in the drivers seat and lock the door, all 4 doors lock ok. But i cant get the doors to lock remotely from the key, they unlock remotely, this video i made shows the problem:
I have also tried to unplug each door loom at the connector going to the doors, first i tried unplugging one door at a time with the other 3 connected, working round all 4 doors with this technique, then i tried disconnecting all but one door and did that with all doors, but regardless of what way its done i still have the doors trying to lock, then unlock straight away.
