Most dash-mounted switches can be removed using the same basic procedure. Remove the trim panel which the switch is secured to. Trim panels are usually secured by a series of screws and/or clips. Make sure you remove all attaching screws before attempting to pull on the panel. Do not use excessive force as trim panels are easily damaged. Once the trim panel has been removed, unplug the switch connector, then remove its retaining screws or pry it from the mounting clip. Always disconnect the negative battery cable first.
