Sure sign the blower motor is about to seize of otherwise fail. Fuses should
never just be replaced without the cause being determined and corrected.
Also, as I have written in the past there is no real reason or benefit to
operate the dash heater fan on that high speed. The interior will warm
faster along with the windshield defrosting with the fan on speed 2. Once
moving on the highway turn it off to save it.

It's interesting that David comments on that circuit being overloaded. I
find that fuse brined out pretty regularly! Just replaced it again
yesterday.

That's because the switch body is thermoplastic; it softened and the
contact pressure drove the hot contact down into the switch body.  On
a desert island you'd find a way to fix it.  Bus Depot, Van-Again, no
doubt others have new;  Chris Turner <jordanvw@aol.com> no doubt has
used ones -- if used, try to get one from a rear blower, they're the
same switch but less load on them.  But if you add a relay for the
high speed you shouldn't have any further switch problems.  On the
1.9l the circuit is overloaded but the 2.1l don't need a new circuit,
I think, just getting the load off the switch; so you can take the 30
terminal off the switch supply, cut and use the high-speed wire from
the switch for the 85 terminal; 86 to ground and the other one to the
fan high-speed wire.

Yrs,
