2002 C240 power issues
 

I have a 2002 C240 that tends to die over night. I have installed a kill-switch attached to the battery so when I am done driving the car I can flip it and the battery will no longer drain. Anybody has any suggestion on what this could be? The car sometimes idle's rough when sitting at a stop sign or red light as well. Thanks in advance for any suggestions or help.

if you have power seats it could be the seat adjustment control modules under the seats.. if the part number starts with a 203 then they should be replaced. if they have a 211 number then they are ok.

Thanks, when daylight comes I will check them out. If they do need replacing what price range am I looking at for a set?

2001 C240. Seat control module drains the battery in 2-3 days. I looked underneath the seat and found a bunch of plugs. 4 in the back and 2 or 3 in the front. Which ones do I disconnect? Someone mentioned here that you can splice a wire that is for keeping the seat control on after the car if off, and that should fix the problem. Either way I am completely lost. Any pictures of the steps needed would also help.
