OK, so I’m trying to track down this cooling fan problem. When I turn the a/c on, only the passenger side fan comes on.(People assure me the driver’s fan is supposed to come on to. Can somebody confirm this is true? I have a 96’ Honda accord LX) Here’s what I’ve done so far: Direct power to cooli…

Ok, good news I’m not an idiot. My voltage check wasn’t reading right because the main ground off the battery cable to below the engine was corroded as all get out and the wire insulation was exposed and fraying!. I did the laborious task of getting it off, cleaning off the corrosion with a wire bru…

This is why you need to check the circuit. There is a problem between the relay and the fan connector if the voltage drop is that much. Did you try running the 12V power through the relay connector with a jumper wire? You may need to run a new wire from the relay to the fan if you cannot isolate the…

Most likely the problem is with the fan itself. I had this same problem a few years ago with our 97 Accord and it was the fan motor. The passenger side fan is the radiator fan and is supposed to come on both by coolant temp and AC on. The drivers side fan is the condenser fan and come on only wit…

The radiator fan relay is in the underhood relay panel. On the drivers side of the radiator, on the frame near the top are two relays, the relay towards the rear of the car is the compressor relay, the one towards the front is the condenser fan relay. Remove the plug.

@Keith I shorted the relay wire to the the driver’s side fan and it came on! Thanks so much! That’s so weird that it’s the relay, when both were able to turn on the AC clutch…real head scratcher http://www.flickr.com/photos/abracadabra-/7028497251/in/photostream/

A brand new relay is only $31 at autozone. As for which pin is which. looking at the picture in your post, A is the upper right, C is upper left, B is bottom right and D is bottom left. That’s as the picture is oriented in the post. In other words, as viewed C A D B

If you are going to test it out of the car, you need to apply + to D and - to B, then check for continuity A to C. If the relay checks good, then turn on the ignition and the ac and check for 12v at the yellow/white wire, pin D on the connector.

ok, it’s not the relay, it couldn’t be the relay because both switch on the ac clutch. In better news: I repaired the small leak in my AC system. I had an o-ring that was about flat as a pancake on the high pressure side(Which makes sense because high pressure does tend to flatten things!). Since I…

Look for a blue/yellow wire and white wire. Short the two pins together and the fan should run, even with the ignition switch in the off position. If it does not, the fan is bad. Be careful, there is a yellow/white wire, do not mix this one up with the white wire.
