Re: Fan Speed Resistor Pack?

[Jason Lile <jason@xxxxxxxxxxxxxxxxxxxxxxx>]

Your fan speed resistor is what's commonly referred to as the "sword computer"
on the E32/34 cars.  It is located at the lower rear passenger side of the
heater box.  It's extra fun to get to on a 5er because there is not as much
room.  The procedure is usually performed with the top of your head resting on
the floormat ;)  A new one is around $300-$350 list price and they typically
sell for about $150 used.  If you end up needing the part number, let me know.
Good luck.
