    Did you clear the faults after swapping the microswitch?

    Yes cleared all codes - seems to go away and then out of the blue come back again. As far as I can tell, the microswitch is working as it should, the window drops down as it should. The rest of the car seems to be fine.

    The only thing I've not managed to track down is why the remote suddenly stopped working. I pulled the CCM out and it appears fine. Considering the central locking module below the subwoofer was submerged in water and still appears to be working OK (was the source of the K line fault) and this one had some mild corrosion to the pins...

    I've also noticed that the alarm light is not flashing on the car door....?

    Have you checked whether all the wires going into the drivers door are OK with a DVOM? It's not uncommon for some of the wires to break with the opening and closing of the door.

    Well I've just noticed that the passenger door is lit up and the driver's door is not so that may suggest another cable is damaged. Question is, would that cause the alarm problem?

    I will try and check this out.

    So no obvious cuts in the wires. Do the LEDs burn out?

    Still no joy getting the key to connect and it's still setting the alarm off sometime!

    In other news, the roof isn't working anymore - the button on the central console does nothing. The lock/unlock button is still working...
