Possible Main Fuse???

[FactoryPilot]

Some weird stuff happening on the Cerbie.

Passenger window goes down but will not go up.
Drivers window will not lower or do anything (including drop when door opens).
Rev counter is bouncing all over the place.
Hazzard lights came on by themselves.
Full beam came on by itself, despite headlights not being on.
Remote alarm key fobs don't seem to work (both and the batteries are ok).

Any ideas? Is it a mixture of issues or could it be one main problem causing it, such as main fuse?

Ta, FP

I had a weird few weeks with my doors / windows...eventually tracing it back to a broken speaker wire in the drivers door - how the stereo is connected to the windows, I'll never know but it fixed it....but as you've such an array of weird happenings I'd guess it'll be something more common - like the main earth - might be worth renewing it / adding a second

I had similar 'comedy effects' the once, hazards flashing, windscreen wipers going, doors wouldn't open. Problem was traced to a faulty earth conection eventually. Not by me though!
