2007 GL450 rear window and lights not working.

Hello everyone, I’ve noticed the other night that my passenger side headlights were not working, ok, so I just replaced it with a new bulb and still not working, so I then noticed that the turn signals were not working as well, and only the turn signals on the outside mirrors were still working, but that wasn’t it! Both rear power windows and a power lock had stopped working as well, the battery is brand new and I’ve checked every fuse in all (4) fuse boxes and All are working well, could it be a (RELAY?) (I’m hoping) if you had this problem pls help me out. Thanks

If you’ve checked all fuses and relays the next step is to have the car read with a Mb Star / DAS scan tool for current or stored codes that may be related to one of your signal acquisition modules (SAMs).

Did all of this start when the new battery was installed?

The battery was a few days old, this happened afterwards, it seemed they all had blown at the same time, I’m hoping it’s a relay.

just a new battery (not the auxiliary battery) everything was working properly until I heard someone yelling, “turn on your lights!) that’s when I’ve noticed.
