Weak windscreen blower

[staccato]

When the heater control knob is turned to the windscreen i.e. de-mist, the air being blown is very very weak, even when all the vents are closed off elsewhere. When you turn the control knob to front facing, or feet, it blows out really hard.

It's annoying as I did a 30 min journey with no hint of the screen demisting.

Any ideas?

Thanks

possibly the dampers in the system not closing/opening fully, take the heater controls out and check the cables for travel and sticky movement, WD40 them up and try again

ok will do. The rotating switch doesn't quite go all the way to windscreen. It will if you hold it, but then springs back one or two notches. Maybe this is it

how powerfully are everyone else's windscreen blowers blowing? Mine is a trickle at best.

The blower in no.41 is like a hurricane! Well, almost
