hi all,

Can someone walk me through the process for tracing a failed electrical
part such as power mirrors? Maybe clue me in on what I would need to do
such a thing. I've checked the fuses and they seem fine, but I am unsure
of how to tell why something isn't working and where to start the
deductive process. I would really appreciate any input from you very
knowledgable folks. I really don't want to tear into my untouched door
panels unless I know what to look for. :) Thanks in advance
