accord exr 1990 - radiator fan comes on days after stopping the car

Hi all,

My radiator fan goes on and off a long time after stopping the car: I
hadn't driven the car for a
couple of days, then the fan goes on and totally kills the battery.

I'm totally lost. What could be the culprit? A heat sensor or a
shortcircuit?
Is it expensive or hard to fix?

Thanks for your answers.

Defective radiator fan timer is a candidate, possibly a very
strong one. It's come up here before as problematic. See
http://groups.google.com/group/alt.autos.honda/browse_frm/thread/e162c317d73b6a40/6c347aaffa3e1d26?lnk=st&q=radiator+fan+timer+accord&rnum=5#6c347aaffa3e1d26

For more info, see the Accord manual at
http://www.honda.co.uk/car/owner/workshop.html (Electrical
section, then "Cooling Fan Control") and possibly as needed
the parts diagrams at www.slhonda.com .

 

I'm sorry for my hasted post. After looking into more detailed I
discovered many long threads on this topic.

Thanks a lot for the pointers.

Don't apologize. Maybe someone else is having the same
problem but does not yet know about the archives. Plus, your
report adds another point to the anecdotal database.

Besides, it might not be the timer.

Updates are welcome, to help others in the future.

It's the fan switch. There are two if you have A/C. The switch goes bad
all the time on those.

The timer unit is much less likely to be bad than the switch.
