Have a 97 accord se, pretty good at trouble shooting and general work, But have a crazy problem. The radiator fan does not come on and have checked fuses and changed cooling sensers. And to add to this when I turn the A/C on the radiator fan comes on not the A/C fan. Have owned the car for like 7 years and the wiring has not been messed with. Does any one have any guess on this. Thanks

 

Just so I'm clear.

4 or 6 cyl?

Drivers or pass side fan, again want to be sure before going further.

The pic should help, we can help more if needed.

 

Have you jump the radiator fan switch two pin connector just for the hell of it to see if the fan kicks on? If it doesn't, you know there's something wrong downstream.

Also, you did add power and ground to the radiator fan just to be sure it's not out?

 

Have you taken the car to a mechanic? Maybe they messed around with something on accident. I know this might seem a question that doesn't need to be asked, but: Has this ever happened before? Is this the first time? I think it is implied that this is the first time, but just to be sure. I'm also actually having trouble with my SE's radiator fan. One day it poured rain while my hood was open, and when it finally stopped I found out my car battery was dead. It turns out that the radiator fan on the drivers side was continuously spinning very very slowly. Finally, after a couple days, it stopped (phew, I was tired of having to disconnect the battery terminal every time I got out of the car.) Then it stopped working completely. Now only the fan on the passenger's side turns on. The a/c however works fine. If any of you guys off the top of your head know what happened to my fan, please tell me.

BTW I believe SE models in 97 only come in 4 cylinders. Not sure though.

 

Thanks for some feed back- It's a 4 cylinder 4 door auto. The fan on the passanger side (radiator) fan does not come on. But it does come on if you turn the A/C on and the driverside fan (A/C FAN) never comes on no matter what. And no fan ever comes on after the car has been running and you turn it off. First time it has done this. Never took it to any shop for any work.

 

A/C Condenser Fan:

1. For the A/C condenser fan, the motor may be dead. Unplug, the fan motor connector and apply direct battery power to the motor to see if it spins strongly. (Alternatively, if you have a multimeter or voltmeter, you can check the connector to see if it gets 12 volts when the A/C is turned on.)

2. If A/C condenser fan motor turns out okay in step 1 above, it may be the condenser fan relay (you stated fuses checked).

Radiator Fan:

1. So, sounded like you changed thermo-switch A (located on or near the thermostat housing, lower radiator hose) and thermo-switch B (upper radiator hose)?

Then it may be the radiator fan relay. Try swapping the power window relay to see if it changes anything.
