Whoever owned my 924 before I fancied themselves a bit of an electrical
engineer, andmanaged to really hack up the car.  The car had AC in it at
one time (I am unsure if it was factory installed or an add on).  This was
removed prior to the person I purchased it from (or so they would lead me
to believe).  So the bright boy decided it was silly to have two fans, but
only one working.  The solution?  To hook both fans to the fan
thermoswitch.  Now when I got the car it was fairly cool out, so the temp
gauge stayed solidly in the lower half of the temp gauge.  I ran it a bit
hard at first, and it did nothing, but stay there, so I really didn't check
the fans (and if I had, I would have assumed all was well, since it wasn't
over heating, and the fans were off).  I got it back last night, after
having the clutch replaced (another sordid story), ran it home with no
problems.  This morning I drove it to work, and it turned out to be a hot
day.  Of course in the morning it was cool, and again, no problems.  On the
drive home however, I hit the freeway, took my exit, had to pause behind a
truck at a stop light.  The semi took it's sweet time to turn left, so I
had to sit for a light or two.  After turning, I glanced at the temp, and I
was deep in the red.  I backed off the throttle, letting it more or less
idle it's way to 50 or so, and the temp slowly backed down.  I babied it up
the highway to home, with the gauge settling at dead center, rising slowly
as my speed had to drop for traffic, but it stayed cool enough all the way
home.

So I examined the fans tonight, and they are functional, but I have yet to
test the switch.  My thoughts are, however, that if this is a silicon
switch it may not have the current capacity to sink both fans.  Of course
it is also possible this is a 30 year old switch, and simply died of old
age, or a marginal newer one that finally had had it.  

So the question is, would a new switch be capable of sinking both fans, or
should I slap a relay between it and the two?  I agree that if you have two
fans you should use two fans, but also believe in the K.I.S.S. philosophy
and adding a relay will add a second point of failure to the system.  Any
ideas?

Thanks,
Paul
