Thanks for posting!
You're most welcome.
Looking at the diagram part no.6 appears to merely switch ON/OFF the earth for the auxiliary blower. It looks like a manual override switch.
What is a little odd however is that it carries a lot of current (it seems) from relay 5 hot terminal 30-notice fuse 7. Perhaps another relay between terminal 30 (relay 5) and blower 4. Otherwise the override switch may burn out, then again, perhaps it will be used too rarely to be a worry. I would guess that blower 4 is a fan on your evaporator? Looking at the fuse this would pull a bit less than 7.5 amps (at a guess)- perhaps a bit high for a switch over the longer term.
