Heater blower/heated rear window switch

10. This switch is released in a similar way to the lighting master switch. If the switch cannot be released, withdraw the heater control panel.

11. Refit in the reverse order to removal.

Steering column switches

12. Although not strictly necessary, access will be improved if the steering wheel is removed.

Otherwise, remove the wheel centre trim.

13. Remove the upper and lower switch shrouds. These are held in place by eight screws with the fixed type steering wheel, or five screws with the adjustable wheel.

14. In theory it is now possible to unclip and withdraw either of the multi-function switches.

In practice it was found necessary, when the adjustable wheel was fitted, to undo the two switch housing screws and draw the switch assembly up the column slightly. The switch in question can then be unplugged, unclipped and removed (see illustrations).

15. Refit in the reverse order to removal.

22. Proceed as described above for the electric mirror switch.

Interior light switches

23. The main interior light is operated by door plunger switches. Similar switches control the luggage area and glovebox light, when fitted.

24. Removal is similar in every case. After displacing any trim which may be in the way, the switch is unscrewed or unclipped and withdrawn from its location (see illustrations). The electrical lead(s) can then be unplugged and the switch removed. Tape the wires if necessary to avoid losing them inside the switch hole.

Horn(s) - removal and refitting

Removal

1. The horn itself is located in front of the radiator, unless an oil cooler is fitted, when it is located behind the battery. Disconnect and unbolt the horn to remove it; remove the front trim panel if necessary for access.

2. On models with twin horns, the second horn is mounted behind the front grille on the left-hand side. To gain access to it, either the front grille or the radiator must be removed.

3. If the horn does not work, check with a 12 volt test lamp that voltage is present at the horn terminals when the horn push is operated. If the horn itself is defective it must be renewed.
