Battery drains overnight
So I've been having some problems starting my car lately, at first i thought it was the battery checked it and it's good then i thought it was the alternator
And when we were taking it out i heard the blower fan runing but the car was off and the key was on the seat so i was like wait is this fan draining my battery? So we unplug the battery and the fan shut off, does anybody knows why is this happening? is there a relay or fuse that i should check it out? and if there is where is located?

Welcome! Please post a photo of the C. How did you check the battery? Quite often the best course of action is to replace the battery as it rules out this from the troubleshooting. Batteries doesn’t last forever.

Make sure you have the correct size of battery. I replaced mine at a battery store, they sold me the wrong one. Went to a second store and they said there are two different sizes for a c300 2009
