P38 Fascia Switch Pack Repair
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.

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.
