Front heated screen question - LX model.

[HARRYSPADGE]

Both myself and my son have Connect LX models (03 & 05) with a heated front screen and heated mirrors.
On the dash centre panel below the heater controls are two switches with heat symbols on them.
Neither of the vans have a handbook so could someone who has the same vehicle please advise which switch does what.
One switch has a rectangular shaped heat symbol and the other has a windscreen shaped heat symbol - now logic would say that the latter switch is for the front screen, so could somebody please confirm this for me.
Thanks in advance.

And rear doors if they have glass, or rear window (if you have a tailgate)
