No power to light fixtures or switch in garage


First off, GREAT SITE!!! Theres a wealth of information here.
Here is my situation:

I have two light fixtures in my garage that I would guess are both controlled by the switch at the entrance. Both light fixtures are missing and have exposed wires. The closest to the switch has two whites; two blacks; and a ground. The other has one white; one black and a ground. There is no power to either set of exposed wires with the switch in the on or off position. There is no power at the switch either. No idea what breaker they are on. Wiring everywhere else is good, I replaced all the switches and receptacles in the house. No open grounds, also, the switch in the garage does have continuity.

Could the garage be wired in such a way that the circuit will only complete if both light fixtures are installed? If so, why would there be no power at either switch or fixtures?

Are the wires exposed or is this a finished space? If it is all exposed then you can physically trace the cables back to where they originate. I would check the obvious first-Is there a breaker tripped? Breakers don't always appear to be tripped and they could be. Physically turn them off one at a time and back on again. Are there any gfci outlets tripped. Are there other outlets or lights in the garage that are working? Is there a sub panel at another location that you haven't checked?

No the power from the panel can come into the switch box or the light fixture box and is not series wired through any fixtures.

Thanks for the advise. I will double check all breakers again. Oh, and yes it is finished work... Just no fixtures, condo is 20 years old.

There are 2 more receptacles in the garage. Both are on different breakers. One powers the garage door opener. The other is a GFCI. I have checked all other GFCI and all are wired properly and working fine. However, I did notice that one GFCI in the master bath has wires for both LOAD and LINE. I tried to figure out what other locations are being fed from this GFCI.... and nothing. No lights or receptacles lose power. Hmmmm

No other sub panels anywhere

I re-checked the breakers, they are fine. Still cant figure out what the line feeds past the gfci. Any further suggestions?

The best way to find out what is on the load side of the gfci is to disconnect the load and see what doesn't work. Remove the hot from the load side of the gfci and cap it. Make sure that you turn the power off first. After removing wire turn the power back on and see what is not working.

Actually you can just push the test button and trip the GFCI and that will kill power to the load side.
