Hi, I am new here!!! I have looked all over for the answer to this problem, to no avail. I am not a professionl mechanic, but I am pretty handy. My 2001 SLK20 has a battery drain issue. I have done EVERYTHING that people suggest, hooking up a multimeter to the negative terminal, and to the cable, then pulling fuses. I even did the light thing where I could see the light if it went out when pulling a fuse. I pulled every fuse from under the hood, and on the drivers side to the left of steering wheel.......but the light never went out, so there is still a drain somewhere. One place said there was a fuse box in the trunk, but my 2001 doesnt have one.........I looked and looked.......I have had the battery checked and it is good.....but it drains in about a day and a half.......anyone have any ideas?? Thank you in advance....this forum is awesome!!! Woody

battery drain

look in the electronics box at right front shock area, inside there is a module called mulitfunction module, there is a k - 40 relay, pse pump in right rear etc , use an amp meter , inductive to check for draw, usual suspects in car is radio, teleaid control module , if it has it, and control modules

My brother had the same issue and this is what he said
"The fan reostat was shorted and the fan was on continuously. Caused by water coming into the cabin because of clogged drain holes"

"I figured it out when I heard the soft whirring sound coming from the fans with the car off and then looked it up online and there were folks that said that the reostat failure causes this."

And about fuse location in trunk
"the fuses in the trunk are for the roof, there are fuses on the driver side the panel is visible with the drive door open on the side of the dash"
