My C32 drains the battery. When all systems are down (unplugged ground cable from battery) I get a drain of almost 3A! When I remove the Comand fuse (No 64) it drains 0.9 A less. I have not checked the rest of the fuses, but do you have some ideas why the comand drains battery?
My seat module are already unplugged, so do you have some idea what drains 2A?

There have been several problems reported with a fan that sits behind the comand running constantly, it sounds like you may have the same problem. Try doing a search for comand fan, and see what turns up.

ya, the 3 killers are the seat modules, the fan from comand, and the overhead light module

thanks! Do anyone know where the fuse for the overhead light module is located?
Is the light module located inside the light/button "package" between the front windshield and the sunroof?

I don't know the exact location. You should pm topgun32 or do a search for the fuse chart

I am having the same problem! My command was pulling close to an amp and the overhead console was pulling some juice as well so I have my overhead console unplugged and I installed a switch to my command to turn the power off because the fan was running 24/7. I am currently looking for a used overhead console because the stealershipwants 580.00 for a new one and I will live with a hidden switch to turn off all power to the navi. And for the record the draw I was having cost me a new battery, alternator and a tow. And the worse part is the first (NEW) alternator was bad so I had to change it out twice!!

Are you taking the Key out at night, that alone will drain my ML55 battery in about 24 hours???

my Comand has always draw some charges, but not enough to drain my battery.

PLM, both driver and passenger seat can cause battery drain. make sure you check both. not sure where's the fuse for the overhead. did you lost the fuse chart? i'll check if i can find mine.

I has a similar problem 1.85A draw and the battery would go flat after 2 days , I traced it down to a can bus problem the dash was not 'going to sleep ' and keeping all the other functions awake .. as the new instrument cluster is aprox 700 gbp or well over 1000 dollars so I have installed a switch on the can bus and if the car is bieng left over night I switch the dash can off and the rest of the car goes to sleep and the drain is 15mA .
