Set aside a day and start early. I have done this three times and it still takes me about 4 hours to complete. Mine is a 51 plate 2.8D LWB.
Open glovebox and remove two screws just inside the lid facing down
Open bonnet and remove two hoses to the heater, and three 10mm nuts, this will allow a triangular plastic retaining plate (10" x 8") to be removed. Remove two screws holding hazard warning panel and lift panel on to dash.
Starting on the nearside, remove screws holding lower dash, four in total.
Go to drivers side and remove screw from lower dash three in total, remove the radio and ashtray, remove two small phillips screws and remove ashtray holder.
Go to the gear lever, prise the bottom of the gaitor away (it has a large square sprung retaining clip) then remove the screw immediately behind the gaitor, once this screw is removed the plastic gear lever suround can be lifted off.
On the floor under the gearlever is a kick panel in front of an ECU, remove 4 x torq screws holding kick panel, and three 10mm nuts holding ecu, move ecu to under the clutch pedal (do not unplug it), under the glovebox is a little flat electrical box, remove small bolt and clip out of the way.
Remove 4 x 10mm nuts and lower the gear lever to the floor (leave the cables attached). Unclip the wiring loom and all the connections under the glovebox, and tuck it out of the way, remove 10mm bolt on nearside wheelarch, 10mm bolt set back in the centre and 10 mm bolt under the gear lever position,
Remove the two scres holding the heater panel to the dash, pull the now loose heater box forward and manouver it left and remove the two top screws holding the heater control panel to the heater box (top r/h is hiden and awkward) then the bottom two, drop the heater panel forward and manouver out the heater box, refitting is a reversal.
Drop the heater box out, just took you 25 minuites and a real struggle, refitting is just as bad, take photos as you strip it and make notes, otherwise you
will forget something and have to remove parts again.
GOOD LUCK:bang::bang::bang:
