Hi mate, check the wiring to the battery from the alternator and the starter motor. If there are any issues, like a loose connection, this can cause the battery to drain slightly, and IF that is happening it can cause the electrics to play up.
I had an issue with this a while back and the fix was to replace the wire that run from the battery to the alternator as it wasnt giving a very good connection. So when I put the window down it wouldnt go back up, kept dropping.
Might not be the cause of your problem, but it is a free/relatively cheap fix (my replacement wire cost £3). Best of all it is free to check it........
