90 accord fan runs with car off

condenser fan will start and run in driveway with car cold. changed temp.
switch no help. changed relay no help. pulled cooling fan fuse and fan
shuts off. pulled radiator fan fuse and fan shuts off. 2 fuses on the
wiring diagram do feed the fan timer. suspect fan timer. I cannot find
the timer. Can anyone help me?,

Usually it is located under the driver's kick panel on Hondas, I think.
Maybe someone else here knows for sure.

Could also be that the thermo sensor has shorted. Not sure on your
accord, but it is usually on or near the thermostat housing. Disconnect
it and see if the fan stops running.

Remco, thanks for the reply. What is the driver's kick panel? I changed
out the temp. switch on the thermostat housing with no improvement. I
disconnect it while the fan is on and no change, fan keeps running. I
think fan timer is the only thing left.

 

I seem to remember (it has been a while but this was an early 90
accord) that it is where your left driver's foot is, up a little ways
towards the dash. The kick panel is that piece of plastic that your
foot would hit - I found it after I took that thing off.
It is a black box, about 3x3x1" with a decent size connector on it.

I have also heard that on other model hondas it is under the passenger
seat.

The two links below suggest the timer is under the dashboard for a 1990
Accord, on the left side. One is an ebay link to a 1990 Accord timer. (I
threw in the search terms {timer Accord} at Ebay to find this.) It has a
photo, too, that might help. The other is from a Usenet groups thread on
this subject. This question comes up a fair amount.

From the Usenet thread and the wiring diagram, the part I see with seven
wires going to it (excluding a ground) and temperature switches A and B
connecting to it is called the "Radiator Fan Control Module." I gather this
is the same as the timer or it contains the timer(?).

For other Honda models, as Remco said, there are indications the timer is
under the passenger seat, in a small black box. These I see for 1980s or so
Hondas. For circa 1995 Hondas, there is still another location indicated.

I was looking at the online Honda parts sites that are popular and can't
find this part, so far. E.g. www.slhonda.com . Tricky...

 

It's listed and shown in a drawing under "Control Unit," item 3, "timer,
radiator fan" at

http://tinyurl.com/a6a29 (hondaautomotiveparts.com, but it should also be at
slhonda.com, since the drawings are identical at these two parts sites)

It's shown to be under the dashboard, on the left side.

$105. Whew. Go ebay.

 

There you go. This group is great, isn't it? Now you have a picture to
compare to.
I remember I had to take the kick panel off to find it. It is up a
little ways, towards the dash.

Remco

 

Yes, it's great.

One of the posters to one of the old threads on this also said it's up a
little ways in the dash and kinda tricky to get to, as well.

 

Remco and elle, thanks for the tips on this one. I bought the timer at
Ebay and recently installed it. It was a bugger to get at but I did it
and it took care of the problem. thanks again. you saved me a lot of
time and trouble. chub

 

You're welcome -- glad you got it all back to working again!

 

again!

Likewise. Thanks for the update. Helps my learning and I'm
sure others'.
