Switch on switches 1 & 2, wait a minute and switch off number 2. Enter the room. Whichever bulb is on is wired to switch 1, whichever is off and hot is wired to switch number 2, and the third is wired to switch 3.

turn on two switches for few minutes and leave one off. Then, right before you leave turn off another one so that one switch is up and the other 2 are down.
