To replace the wiper switch on a 2003 Ford Expedition, first disconnect the negative battery cable to ensure safety. Remove the steering column cover by taking out the screws, and then detach the wiper switch by unplugging the electrical connector and removing any retaining screws. Install the new wiper switch by reversing the disassembly steps, reconnect the battery, and test the switch to ensure proper functionality.
