A Jaguar Parts Supplier that covers XK 2010

Hello

I am having a lot of trouble finding a parts supplier that doesn't just say they have the parts and when you visit their site there's just the usual "Not Found".

I am desperate to sort out an drivers door window switch problem, when the drivers window would not work i disconnected it. I cleaned it and plugged it back in. As soon as i did the seat control module stopped working. I disconnected the window switch and the seat control worked. with the help of a friend we tested the connections with a probe. There are just three wires, White with Black stripe, Black, and Blue, the white and black one i think is the

L I N connection now this was the weird thing, the other two wires showed Red for one and Green for the other on the probe, but the Black and White one just flickered an orange colour very fast. It could have been both red and green flashing quickly but it looked orange.

I have purchased two replacement switch units and made sure they were the same part number, both would not work, so i thought i would try and buy a brand new one but i cant find anywhere to get one. Can anyone let me know where i can buy an 8W83 14540 AB Right hand door switch unit please. Or if anyone has an idea what the problem could be please.

Thank you for taking the time to read this.
