In the last couple of days, Big blue's Heater fan (the one up behind the glovebox) has gone a bit squealy / whiney for up to 5 mins till the car warms up,   Lowering the fan speed reduces it, changing air direction etc has no effect, so pretty sure its the fan.

Getting to it looks 'fun'

so reluctant to do it more than once.

Anyone got any good silencing tricks, or is it best to get a replacement and go for the swap out.

Im debating a quick squirt of wd40 behind the pollen filter and hoping for a result similar to how it can help on belt squeal.

Pollen filter out and drop some oil onto the fan spindle, visible once filter out

Mine went through a phase of doing this, then it stopped, and has been quiet since. Might just be a bit of grit in the bushes. Guessing they're oilite bushes, so an overnight soak in oil  and remove any burrs on the shaft is probably the best you can do.
