all the light switches on a circuit are not working

[mcharon]

i have 4 light switches that are on the same circuit and none of them are working. how would you troubleshoot this problem?

thank you in advance.

First make sure you don't have any GFCI receptacles in the bathroom that are tripped then:

Are any rooms on the same circuit and working? Lighting and receptacles can be on the same breaker, but IMO this is a poor way to do it, since trips almost always happen from outlets.

Start in the room closest to the panel and take out the light fixture in the room and check for voltage.

The last room where the power is working is where I would start, or the first room where it isn't working.

If you have access to the ceiling, checking how the wiring was installed will be a big help in finding the problem

Start closest to the panel.

How about more information? Is this a four way switch set up to one fixture? Does each switch control a separate fixture? Knowing what is supposed to happen is important to diagnose the problem.

Change all of the light bulbs.

As Joe indicates, you need to furnish more information for anyone to steer you in a logical direction. First, determine exactly what is dead. Is it just the lights controlled by these switches or are there outlets dead as well. Are these individual light fixtures, and what rooms are they located in. Sometimes a large center hall fixture will be supplied by a dedicated circuit if it has lots of lamps on it, and sometimes an entire floor of a house can be on one circuit if it's small enough

I would start by checking for a tripped breaker, even reset it.
