They worked, now they don't. Fuse is good, they are just dead. Working yesterday, then I got in last night to drive and now nothing happens. Any ideas?

Simple things first... check your flasher?

then check your bulbs

Check the following items:

- wiring,
- contacts,
- switch,
- bulbs,
- ground connections.

Any of these things can cause intermittent failure. My first bet would be the bulbs, sometimes when a bulb has nearly worn the filament breaks but gets "reconnected" temporarily by vibration.
