Rover 75

[Hog]

I'm open to offers on ideas for this one......

The missus has a T plate Rover 75 (2.5 V6) and since the torrential rain the other night has developed some odd electrical maladies.

Wipers stay on with ignition off and key out!
Indicators and hazards work, but no indication as such on the dashboard.
Full beam indication light no longer working.
Electric seat movement no longer working.
Radio / screen no longer working.

Worst of all it now has to be jumped every morning as it's going flat overnight.

Done a bit of google research which shows up a comon fault of a blocked drain near the ECU causing various woes, but these seem to relate more to rough running rather than what we've got.

Anyone got any ideas? Solve this one and it's uber brownie points for me.
