Hello everyone , so I was gone for about a week when I got home to try to start my wagon it would not start and I had a red warning message about my brakes. I than jump the car and the car started right up but the engine fan was not spinning I than checked the radiator fan relay marked O and replaced it with another and the fan is still not working, very confused if anyone could help it would be much appreciated

This is what happens when you let the battery run down. I'm guessing it's a front SAM module problem but there's no way to know for sure without a mercedes scan tool. Also if it happened in just one week your battery is on its way out. Good luck.
