Turn the problem around -- your heater blower fuse blows when you turn on
the wipers. ;-)

Check that the fuse is as specified (16 amps on the 1.9l).  Put an ammeter
in place of the fuse and measure current draw of wiper and blower -- blower
ought to draw about 12 amps on high speed.  This circuit is somewhat
overloaded right from the factory, can cure by using the blower high-speed
switch position to drive a relay that powers the blower from a separate
circuit.
