Dave,

Not a relay expert but I know in our Saabs there is a failure trend in the
headlight relay that makes them stay on regardless of switch or ignition
position. So some can fail 180 degrees opposite of what you expect.

Do you have a/c? seams to me since the design of the a/c system switch
forces on the cooling fan this switch could be failing. I know that my 86
westy will have the cooling fan on with the rear a/c fan on (no compressor
engagement needed). Don't know if that is by design or how the PO got things
screwed up!

Shawn

Any ideas what I should check.  The radiator fan comes on low speed when I
turn the ignition switch.  It runs continuously regardless of temperature
(even if sitting overnight).  It goes off when I shut the engine off.    I
replaced the fan switch with a new one and no change.  I jumped the wires
that go to the switch and it is operating correctly, both high speed and
low.  I haven't tried replacing the relay behind the headlight b/c I thought
if that goes bad, the low speed fan would never come on.   Anyone have
experience with this problem.

Thanks
Dave
