Please can someone give me some advice about how to change the heater
panel bulbs in a V40.  I have:

...removed the three heater knobs
...levered off the facia

but I am now stuck.  I can see the blown bulbs through the white casing
but do not know how to reach them.  I assume that you have to remove
the switch control but am unsure how.  Any help would be gratefully
received.

I last did this with a 440 and once the facia was removed the bulbs
were exposed.  This time it is slightly different

Many thanks

Russell
