Battery Drain

[jibcl500]

Ive had a problem with the battery on my CL500, if the cars left for a week the battery can be nearly flat and Ive suspected something electrical is still working when the cars parked in the garage.
This morning I went outside and there was frost on all our cars but the screen on the CL looked like this (see attached) so I thinking possibly there must be a blower motor still running behind the dash, am I on the right tracks or does someone here have another suggestion please. All the other cars on the drive had a complete frost on the screens.

Do a drain test jib, the 140 do not have many problems of this nature. spend a few nights in the car and listen for any fans etc

Pulled all th fuses last night and they all had a dark grey tinge to them so I polished them all up, I also found 4 or so fuses fitted where the list shows them as being vacant!!! so they came out, noticed tonight the car started with no signs of a low battery, will monitor the situation over the next few days but me thinks the blower is doing its own thing.

If you park into the breeze that's what you get as the air temp gets above freezing, assuming that you have the heater set to send some air to the screen.
