This is a friends car and my first time to touch a nissan. Supplied direct battery voltage to both fans, one was not running at all, the other one is running slow and rough.
Replaced both fan anyway. When I checked for battery voltage in both fan connectors, I get none.

1. Can somebody help me to find a free wiring diagram for the condenser fans.
2. Location of specific relay/s and fuse/s related to the operation of the fans?

Thanks in advance pros.

Thank you very much. That was very helpful. I think it would be very similar to a Patrol since the motor I saw in there has also a 4-wire. One difference is this car has two fans. One is 4 wire, the other is 2 wire. I guess the other fan would just take its power from the same circuit.

About the triple switch, is it connected to the coolant lines or to the A/C lines? Sorry about the dumb questions. This car is totally different from my civic (the only car I can work on).

To add some more info, this car is an inline- 6 cylinder gasoline engine. A fan is directly coupled to the engine. The two fans are in front of the condenser and condenser is in front of radiator.

You may not have the triple switch you could have a temp switch or none that is controlled by ecm. Because it's not in u.S I can't get the correct diagram. One fan should come on with a/c and the other when temp get s warm etc. You could possibly have two relays as well. Which would be by the fan relay that is shown in pic. I can't really give you much more help on this because we just dont' have it in u.S.

So I put the new fans in, put every thing back. . Fired up the engine, turned A/C on, now both fans are running, except that they are blowing air towards the front of the car. Any way, I just spliced the wires to interchange and they are now blowing towards the engine bay. Not sure if its supposed to be blowing towards the engine because there is no way I can insert the connector incorrectly.

Tnx hmac300. Your diagram saved me from digging wires.
