2008 BMW 750li

My right rear door doesn't seem to have any power going to the door lock, the 2 window shades, the automatic door closer. It makes me suspect that a fuse has blown but I'm not sure where to look.
Is there a relatively easy way for me to check the fuses with a voltmeter, or other instrument?
Thank you for any ideas.

I suggest you repost this in the sub-forum for your specific model.

I am assuming this is an E66.
Visually check fuse 60 in the trunk, it powers the rear passenger door module. The window regulator is also powered by that fuse, is that working?
Do the door lights work?

have you found the fuses and just need to know how to test them?

Visually you can see when they blow.... Or ohm it out.

I checked #60 fuse (30 amp) and it is not blown. The window in that right rear door also is dead. I neglected to mention that in my previous thread. The other 3 windows work fine.
I hope you guys can come up with more ideas.
Thanks much for trying.

First, you need to make sure your car is an E66.
Does fuse 60 have 12 volts going to it when the car is running?
If nothing is working on that door, your door module might be broken.

Should I remove the fuse when checking the voltage with a meter? Or, is there another way to measure the voltage without removing the fuse? Then, if I have 12 volts at the fuse with the engine running, is the door module the next concern? Which of the 6 part #s is the door module? And how can I determine if it is faulty? I assume that the door module controls everything in that door; is that correct?
Thanks much for your input.

Also, my car is an E65, not an E66.

The E66 is the long wheelbase version of the E65, your title says 750 Li.

The door module does control practically everything in the door, it is the black part in the diagram, A210.
You need to leave the fuse in, turn the car on, and check for voltage on both legs of the fuse.

I tried to check the fuses with a voltmeter but could not seem to get the 12 volts on any fuse. I must have had it set incorrectly. It only read 3 volts. Anyway, I found that the # 60 fuse was in the wrong bracket. After I installed it in the correct one, everything worked fine.
I want to thank you for your help and guidance as I have learned some good things from you. All I have to do now is figure out how to set my voltmeter to get the results I need.

Great! The fix was simple.
Maybe your voltmeter is broken. Or the ground lead is not connected properly. Check if you see 12v touching the battery terminals.

I have never in my life heard of a fuse spontaneously moving to a different position....odd.

It was taken out to be checked and put back in the wrong slot!
