Fixed the blower. A previous owner had used an inadequately sized spade connector for the 31 amps the blower takes at full tilt. He'd made it fit by, err, not putting in all the wire

... overheated, corroded, and the current draw
blew the plastic off the fuse, but left the metal bit of the fuse in situ and still working. So that's where the *crack* sound and the magic smoke escaping came from (the fuse) but it didn't blow, just the plastic exploded off of it. Hmm.
It is also odd that the circuit is 30A and by my calculation using a table I found on the Internet (50mV drop across the 30 amp fuse) that makes 31 amps. Course, there will be a margin of error in there. Maybe it is just within 30 amps ... and that was 50mV with engine running; on battery it's 40mV. Checked the wires and while they get slightly warm, they don't get hot. The blower, although it fitted Mk5 no problem, is off a Mk6. I wonder if the Mk6 blower motor is slightly beefier?
Topped up some of the cells in one of the two batteries. But it may be beyond redemption and I'll need a new one for winter, as some of them were very low. The other one is a maintenance free Bosch so nothing for me to top up.
As I had the dash off to fix the blower, I also managed to get the cup holder back in (You can only fit it in from the back of the dash...) - AND IT WORKS! The key is to remember to push the two pegs at the sides down. That is what stops it falling out. You push them up to take the slidey-in bit out. And then push them down when you reinstall it. If yours keeps falling out, this is why

Topped up the oil and the water.
Fixed a problem with slight sluggishness by cutting a hole out of the cheapo floor mats I'd fitted. It was limiting accelerator travel when you put your foot down

And then of course ... Drove it
