P38 Fascia Switch Pack Repair
Removal Procedure:
The Fascia switch pack panel occasionally needs to be removed for such
operations as replacing the bulbs in its switches, replacing faulty
switches and accessing the heater blend motor wiring loom (see HEVAC blend motor page). To remove
the switch pack, the procedure is as follows (once again Ron Beckett has come to
the rescue with the details and photos).
1.
Remove drivers side lower fascia panel and the instrument binnacle trim
panel (see "Instrument
Binnacle Removal" page). Note: There is no need to remove
the entire instrument binnacle as dictated in the official shop manual
-- just the lower panel and the trim panel surrounding the instrument
pack -- this exposes one fascia panel mounting screw which is hidden
under the surround.
2. Remove the center console side trim panels. See "Center Console Side Panel Removal". This
exposes two more of the mounting screws.
3.Remove Radio front panel applique (pull the knob off then pull the
cover off to expose two
more of the fascia switch pack mounting screws. For details see this section of the radio LCD repair
page). You do not need to
remove the actual radio.
4. All of the 5 screws holding the fascia switch pack will now be
exposed. Removing them allows extraction of the entire switch pack from
the dash.
5. You can now disconnect the multiplug from the offending switch, and
release the clips holding the switch in the panel. Then you can get a
good look at the bulb to be replaced.

switch pack on a LHD model, illustrating the overall shape of the
switch pack unit. Photo at left is a closeup of the dash on a RHD model
showing a mounting screw hole that is hidden behind the binnacle
trim. (Photos by Ron

Bulb Replacement:
Included below are pictures kindly supplied by Ron Beckett showing the
miniature lamps used in the switches. Many thanks also to David Sparkes for helping us
clarify which
bulbs fit which switches in different model years. STC1878 is the green
switch
illumination bulb. STC1877 is the orange one (not
shown). Both of these are used in the front and rear fog light
switches, the ride height inhibit switch, and the cruise control
switch. The hazard flasher switch is illuminated by 2 clear bulbs (part
number STC 1205) up to 1989, but only one from 1999 onwards. All these
bulbs are removed by rotating them anti-clockwise (there is a small
slot for a fine flat screwdriver). The
headlight switch uses a different clear bulb -- STC3115 which does not
have the large base.

the color. |
