I've turned the bulbs and futzed around, but that's all I get
is it the switch then?
There are flourescent lights that have a starter that is seperate from the bulb... you will find a little cylinder of aluminum in the middle of the lamp somewhere. This cylinder can be changed, but most places do not sell them, and thus they are almost impossible to find. It is planned obsolescence for these types of lamps.

There are also flourescent lights that have a "ballast", and no starter. To buy a ballast is more expensive than buying a new lamp.

If you are unsure which type of light you have, turn the lamp on... unplug it from the wall to turn it off... then plug it back in. A lamp with a ballast will come back on. A lamp with a starter will not.

It is also possible to make a bulb flicker and fail to come on, when there is only a partial connection between the bulb's prongs and the receptacle on the lamp where the prongs fit. To solve this problem, you have to keep rotating the bulb around and wiggling it until you get it in the best position.
