'87 300SDL. Constant battery draw. When problem first developed I traced it to the left front seat adjustment circuit. I adjusted the seat and pulled the relay and all was well.

THe problem is back. Pulling the #15 fuse stops the drain.

I checked the seat adjustment switch and there is still a drain with plugs on the switch pulled.

The memory function hasn't worked since I have owned the car.

Question is where is the memory module (relay?) and is it powered all the time.

Thanks,

Tony
