The flashing lights was discussed a couple of weeks ago.
It happened to me one morning when it was F cold, but as you say after a couple of minutes they worked.
Regarding the seat bottom cusion not working - does it ever work?
If it has stopped working all of a sudden it may need repairing.

Check out this thread I started on this exact same problem...
