(applies to post 1997 facelift models) Remove 4 screws, one behind each air vent and two behind the air recirculisation control slider. Remove the heating control panel slowly (no need to disconnect any of the wires). At the top of the vents there are clips which hold the front of the facia onto the pipes for the blower, carefully unclip these (using long nosed pliers) being careful not to snap the mountings. There are also clips underneath the pipes which need to be removed in the same way. The front of the panel should then come off easily with the bulbs now being accessible.
