1999 Jaguar Vanden Plas Drivers Door

This week my vehicle experienced an issue with the drivers side door where the power window switches stopped operating. The switches on all the other doors work fine. I have checked all the fuses which checked out ok. Also with this problem, it caused the gas filler latch to also not operate and the warning bells for the ignition isn't sounding. Lastly I get a message that the drivers door is open even though it is closed. It's difficult to check voltages with everythig being sealed. Please help.

Thanks Leo
