Default 96 Accord Cooling Fan Problem

Hi,

My car is running hot, and I checked under the hood and noticed my
cooling fans/radiator fans do not come on. Even when I cut on the A/C,
the fans do not come on. I even tried letting the car sit and run for
10 to 15 minutes, still the same problem....the fans do not come on.
Do I need to replace the entire radiator/fan unit, or is there a
problem with the fan motor? I have not check the thermostat yet, could
this also be the problem and I need to replace it? Thanks in advance
for all your help.

--------------------------------------

First and most obvious question: How full is the RAD and the Reservoir?
If there's AIR in the cooling system, ONE of your fans will never cut in
unless you turn the car upside down. Your manual says you can fill the
reservoir to MAX. Try it three days in a row (cold engine) and see how
much the system 'sips'.

Fan switch relay is bad.

Check the relay first. The temp sensor is very reliable.

I had the coolant temp sensor( a thermistor) go open on my 94 GSR.

I said "reliable" not "perfect". ECUs are exceedingly reliable too, but
they do fail as well.

Default Re: 96 Accord Cooling Fan Problem

Hey Guys,

Thank you for all your help so far. I was able to trace down and found
the power connection for the A/C fan was disconnected. I check the
power connection for the condenser fan as well, but everything was
connected okay for the condenser fan. The A/C fan comes on now when I
start the car, and turn on the A/C, but the other fan (condenser) still
does not come on. The car does not over-heat now that the A/C fan is
working, but after a long commute (30 minutes or so) I noticed that
there were bubbles in the resevior tank....does this mean a head gasket
problem, or is this related to the condenser fan not coming on? I ran
the A/C during my commute home, and the engine did not over-heat at
all. I did flush the radiator before this commute, but I made sure to
bleed the air out of the radiator, and topped off the fluid level for
both the radiator and the resevior tank. What are your
recommendations? Thanks in advance....

--Craig

Replace the rad cap (with new OEM!). If that doesn't help, get the head
gasket checked out.

almost certainly head gasket.

continue to observe for bubbles. if still present after full purge of
system, gasket's gone and needs replacement soonest before damage to
head or block occurs.
