On the 1.9l it originally comes from the 16 amp fuse about 3/4 of the
way along the strip.  If you have the cover it will be the one where
the cover is melted.  Owners manual and Bentley both show it.

There's been a huge misunderstanding here - we thought that you
tested the blower before you put it in the dash.  Didn't you?

Check the current draw with switch on high (couple seconds
only).  If  it doesn't send the ten amp range on your digital
multimeter offscale then you've got a bad ground, bad switch or some
such.  If it does, then the motor is frozen.  If by any faint chance
the ten amp range on your meter is fused, don't do this test unless
you're willing to expend a fuse, and if it's not fused do it *very*
briefly so you don't burn up the internal shunt.  Normal running draw
of the uninstalled blower is around 12 amps on a fresh battery.

Yours,
