Hi all, I need some help or advice on how to troubleshoot my outside garage lighting that lights up my driveway. There are two lights on either side of the garage door, bot have not been working since I bought the house 3 years ago but I could've sworn that when viewing the house for purchase I remembered them being on. These lights are not dusk to dawn lights and no sensors on them. I just need to find out why my switch is not turning them on. Yes I changed the light bulbs. Inside my house next to my front door, I have 3 switches, all work and does something except for one which I am guessing is for those garage lights. It originally had a Leviton timer switch on it which no matter how I programmed it and what I did to the switch the lights still never came on. I thought the timer switch was defective and wired in a brand new traditional wall switch and still nothing. How do I know this is the garage switch? The breaker on the panel is even labelled for that breaker as (Front door light, porch light and garage light). So where do I go from here? Will a wire tracer work in this case? Can I plug something into the light socket on one end and on the other end into the suspected switch and tell if there is even voltage in the lines and maybe if there's a break/open somewhere? Also, I noticed that on the outside of the garage there are two conduits, one bigger for main wiring of the garage and one smaller, probably only big enough for one maybe two wires, which I am assuming if for the outside garage lights from the house. Please any help would be appreciated.
