Hello everyone!

Maybe this is related to the BCM but I am not sure, I am asking for help in order to be able to identify what to review.
My ML320 (Year 2000) is doing some crazy stuff such as:

• Windows roll down (just a little bit) automatically
• Front speakers are muted
• Electric Seat Switch is actioned automatically
• Windshield wipers are actioned automatically
  
  

This is driving me a little but insane hahaha, any clue what this might be? Thanks!
