I have an electrical outlet on my front porch that no longer works. It was working about a week ago but now does not work. I also noticed a light in my crawl space that also quit working within the past 2 weeks. I did repace the outlet on my porch but it still does not work. I have no problems with any other outlets or lights in my house except these 2. My house was built in 93. Any suggestions as to what i should do to troubleshoot this?
