96 Accord Cooling Fan Problem

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

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.

relay or temp sensor?

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.

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....

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.

Hey Guys,

Okay, the same commute as before and there were no bubbles in the resevior tank. I found the problem with the condenser fan, I hot wired both fans and found that the motor for the condenser fan is bad. I'm in the process of replacing the motor for the condenser fan. Before I left my home this morning, I topped off all the fluids first, but only the resevior tank needed anti-freeze ( it wasn't totally empty, but was pretty low). After my commute today ( no bubbles in the resevior tank), I looked under the hood, and saw the resevior tank was again low.....this was right after I got out of the car from my 30 minute or so commute. I'm now waiting for the engine to cool off, to check and see if I need to add anymore anti-freeze. I will let you know how it goes, but if you have any other recommendations in the mean time, this would be much appreciated.
