Electrical Problems please help

During the night the alarm sounded on Disco TD5 which i reset with the key fob.
When i went to use the car this morning it would not open from the fob and the fob keeped beeping every time i pressed the open/lock button.
Managed to open the car with the key and it started ok however i have now got the following electrical faults.

Car starts on 2nd key position.

Heated rear window does not work

Rear wiper does not work

Rear wash wipe doesnt work

Petrol cap cover wont open

Electric windows dont work.

I suspect it could be due to leaking sunroofs.

Any thoughts on what the problem is ?

Thanks

Tried the car this morning everything is working as it should be.

I guess it has dried out.
