Could be the switch slowly dying.  On mine, however, If I Pushed or pulled (I
forget which) it would work.  Clearly a loose connection inside the switch.
Was able to get a few more years of life out of it by doing this however.  I
think they are cheap from busdepot.

<< With all the recent talk about replacing the heater blower motor up front
it
got me curious about mine acting up. When I turn my switch to the 1 position
the fan does not come on. When I set it to 2, 75% of the time the fan comes
on. In position 3 it always comes on, and then it stays on in position 1 and
2 at the correct speeds as long as I don't turn it off. I am wondering if
this is the blower motor going out or just the switch in need of
replacement.
