I am trying to troubleshoot a rear window deforster not working and
can't seem to tell what fuse or circuit it is attached to.  From
looking at other posts, it might be the cigarette ligher/radio fuse.
The descriptions on the driver and passenger fuse blocks don't provide
a good answer.

It seems like there is power getting to the wires but it doesn't do the
job.  Any suggestions?

TIA
