If none of them work, start by inspecting the wires between the driver's door hinges to see if any are frayed or broken.

Usually won't find a fuse in that system. They use an auto-resetting circuit breaker that plugs into the same type of socket in the fuse box. They can develop pitted contacts but that's not real common.

You can also remove the driver's switch assembly and test for voltage on the wires. Most will have 0 volts but at least one should have 12 volts with the ignition switch on.
