None of the lights on the from panel come on, but there is power to the latch switches and the switches go from infinite to zero resistance when closed. Where should I look next for the problem?

Here is a Frigidaire service manual, although it does not specifically list your model hopefully it will be close

First I would check that the unit is getting 120 volts
If you manually activated the switches to test them, it does not really tell you that they are being activated by the latch assembly. I would take another look as it is fairly common for problems in this area.
If you try it with the door open, inside panel removed, its a good idea to tape some plastic over the front of the dishwasher, you do not want to get wet.
