electrical problem

last night i tried to cut on my master bathroom light and it wouldnt come on. i checked the breaker and it was flipped. so i flipped it back into the correct position and the light came on. but when i cut the light off, it wouldnt come back on. i went back to the breaker, but it was not tripped and i tried to flipp it several times but to no avail. the bathroom fan also fails to work,but the outlets are working fine. we thought it was the switch itself, but now the closet light is not working either. if we need to replace the breaker, how do we do that?
thanks for any help

It's possible that a Black-wire conductor came into contact with a Grounded surface , tripping the breaker ,and causing a break/open in the conductor.

How old is the wiring, and what type of wiring; amored cable, non-metallic cable.?

You will need to examine the wiring in one of the outlet-boxes, and if it's a metal box, you may detect where conductor came into contact with the metal surface of the box by a "smudge"

You may need an reliable voltage-tester. If the wiring is old rubber-insulated conductors, remember , the rubber insulation is very brittle.

I'll guess that you need to distinguish between a "box" and a "panel"; the breakers are in a "panel" ; the switches are in a "outlet-box".

If you are positively sure the breaker in "On" , then examine the wiring in the box where the switches that control the lite & fan are located.

In the sub panel you haven't found yet. It may be in the house near the main cut off which is what you are probably describing.

(Answered just in case he re-registers)
