'03 Boxster: windows inoperative with center switches and when top is brought down/up. Curiously, they still lower/raise when doors are opened/closed. I also get the double-beep when locking the system. Doors do not lock.
I've read the manual about an alarm fault that requires a dealer visit. Before I pay them for an hour of garage time, I thought someone would have a suggestion for what I could try (or expect the tech to say). Thank you.
