I own a 2001 C320 that my wife and I use for a pleasure/trip vehicle. Sparingly driven, garage kept. This morning as I arrived home from work, I happened to look inside the car and saw that the drivers seat was all the way forward, headrest as high as possible, back part of seat as far forward, and all 4 doors locked! I retrieved the key, the doors unlocked, but the drivers seat would not return to position. Car started fine, passenger door and seat operated ok. The drivers seat did lower itself, but that was all. The door seat controls would not operate, and the light under the door is a slow flashing. I do think there was also a light on the switch panel blinking, but after starting I don't remember exactly. It has been very cold here, but last night was only in the low 20's. Any help appreciated, thank you.

 

Well, unhooking and then re-connecting the battery did the trick.
