Default Electric Cooling Fans?

We have a 1996 Honda Accord that the cooling fans are not working on. My son says he has checked the fuse and that it is good. I will try and double check on that. Is this a common problem? This car has over 200,000 miles. We had previously changed the coolant and thermostat but it overheated the other day and that is when we found out the fans weren't working. Don't know about the water pump? Any thoughts or suggestions are appreciated. Thanks!

Need to know if this is a 4 or 6 cylinder.

Do the fan(s) come on if you turn ON the A/C?

Do the fans spin freely? If so, you can try to jump batt + and - to the connectors and see if they spin.

There is also a radiator fan control module that might be the culprit.

It is a 4 cylinder. The fans do both spin freely. The AC isn't working right now. We did turn it on briefly and the fans didn't move.

There is a temperature switch on the thermostat housing that has a green plastic plug with two wires going to it. The wire colors are green and black. Unplug the connector, use a paperclip or wire to short the two pins on the connector, start the engine. Let us know which fans turn on.

Neither fan comes on when I short these wires.

Neither fan comes on when I short these two pins together.

Work backwards, put 12v and ground to both fans and be sure the motors are good.

If they are good, next up the line is to verify the relays. One is in the under hood relay/fuse block, the other is on the driver/left side of the rad...two there, one is for the ac compressor and the other is for the fan.

Okay. I appreciate your help. But how do you check the relays?

On the 96, simple thing is this. If the power windows work, take the window relay and swap it into where the other tow are

One at a time of course.
