If your blower switch is broken you may be able to fix it quite easily.
I took mine apart, and found the likely cause of most broken switches.
The switch works by levering apart a set of sprung contacts much like
those on a distributor rotor. The levering depends on a plastic ball
mounted through a flat beam that carries on from the chromed shaft. When
pressed in (OFF), the shaft presses the ball between two arms that
separate the contacts. When pulled out (ON) the ball slides out from
between the arms and they close the contacts. The ball is made in two
male/female halves, the former passing through a hole in the beam. If
your switch is like mine, the ball has separated and may have been lost,
but not necessarily so as the working area of the switch should be
covered with a removable plastic cover and the halves may still be
trapped in the arrangement. Mine were.
It should be possible to superglue them back together, perhaps with an
extra pin between them. If that doesn't work, I'm going to try two
plastic buttons and a little whittling.
The rest of the switch is pretty rugged, and I'd bet most if not all
failed switches result from this obvious Achilles Heel. An hour of hump-
in-the-back and a little craftwork and your Alpine (Tigers too?) can
really blow again. :)
