On some cars, two switches for heating the front seats are installed in the floor tunnel lining (for vehicles with heated front seats).
The steps for removing and installing the switches on the floor tunnel lining are the same as with the switches on the instrument panel (see "Switches on the instrument panel - removal and installation"). To access the switch from the inside of the floor tunnel lining, use a thin slotted screwdriver to pry and remove the decorative plug (see "Floor tunnel overlay - removal and installation").
