My trunk button does not open the trunk...nor does the key

Customer Question

my trunk button does not open the trunk...nor does the key fob trunk button work. I have to use the key on the fob which is a PITA. I'm thinking a faulty fuse but don't know where the fuse is??
JA: Have you checked the fob's battery?
Customer: yes
JA: What is the model/year of your Mercedes?
Customer: 2004 CL500 w215
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I've tried to research where the actual fuse is because I'm convinced it has to be the fuse. The pump doesn't work but that should not be an issue with just putting my finger up under the rear license plate for it to unlatch the trunk...the I would pull it up manually
JA: Anything else you think the mechanic should know?
Customer: no sir
