Question about 2002 Nissan Pathfinder

1 Answer

Follow-up I had the fan tested today and it runs with an outside power source. They also tested the voltage at the wire going in and said it was only 2.4 volts ? I am thinking that this is not enough to fire the motor. I spoke to the dealer today and they said there isn't a resistor since the vehicle has AUTO A/C. Therefore, the next option would be power module which apparently sits in the ductwork. What do you think ? Is it safe to assume that is the problem or should I have it properly diagnosed ?

That's why I said to bench test the motor/put 12V to it to see if it comes on, BUT you told me that you have power at the connector, which should turn the motor on, but you have only 2.4 V going in. Since you have the AUTO A/C I would look into the blower motor AMPLIFIER mounted behind the glove box on the side of the air box. Its attached with 2 screws. I would look at that next. Your AUTO A/C setup has a "blower motor resistor" and an "amplifier". Check the AMPLIFIER next. Usually when the RESISTOR goes bad, the blower will only work on speed #4/HIGH, but your doesnt work at all. I would look into the AMP assembly. I don't think that the piece is that expensive. $100??? Good luck and let me know what you find.

The cooling fan doesn't work. How do I troubleshoot?


see if you have voltage to it, probe the harness with a digital meter while engine is running and ac is on to see if you have power to it-check fuses and relays (swap the fan relay with a known working relay out of another spot)-if you cannot resolve it then you will have to remove the unit and bench test it by directly wiring it to a 12 volt power source.

Cooling fans not running


HI. I have a very thorough, step by step procedure that will help troubleshoot this issue. follow carefully, to isolate the problem, Use extreme caution when preforming this inspection procedure.



1.Check for broken wires or loose connectors around the fan circuit. Inspect connectors at the fan motor, relay, sensor or heat sensitive switch, and the Electronic Control Module (ECM)--your car’s computer control system. Also, make sure to check for a possible blown fan fuse. These are common and overlooked troublesome spots that may cause a fan to fail.


2.Run and bring the engine to warm temperature. With the engine running, use a voltage test light to check for power to the motor fan. Be extra careful and make sure to keep your hands and tools away from the belt, fan or any other engine moving parts. If voltage is reaching the fan motor, the test light should glow.


3.Turn off the engine after you see the light glow. Apply direct voltage to the fan motor from your car battery using a pair of spare wires. If the fan fails to operate, replace the fan motor. If the motor operates, your problem is in the motor connector.


4.Locate the heat-sensitive switch or heating sensor if the fan motor operates with direct voltage and the test light did not glow. You should find the sensor in the radiator, engine block, or thermostat housing.


5.Measure the resistance across the heating sensor with the multimeter. With the engine at cool temperature (engine off), it should register infinite resistance; with the engine at warm temperature (engine off), you should read low resistance. If both readings state infinite resistance install a new heating sensor, that’s the cause of your failing fan.


6.Check the action of the fan relay if the heating sensor is registering variable resistance. Your service manual should specify the power and ground wires according to color codes and the proper way to test it. If the fan relay fails the test replace it with a new one.


7.Check the connections going to the ECM after you determine the fan relay is working properly. If you find broken wires or loose connectors, make the necessary repairs. If you suspect a defective ECM take your vehicle to a service shop for a computer analysis. In most cases, the ECM is rare to be the cause of a failing fan. The above steps should take you to the root cause of your problem and help you fix the cooler fan.

The blower motor will not work in the vehicle but I can hook up a 12 volt source from the outside and it will work what could be the problem?


I would think that either the fan switch or the resistor would be your problem if you've ruled out any fuse or wiring issues. By testing the voltage going in & out of both components, preferably with a digital multimeter but a 12 volt test light can be used, you will eliminate purchasing parts needlessly. If you end up getting voltage to the fan then see below remarks.

The blower motor still could be bad depending upon how you're jumping it. The vehicle wiring is only equipped to send a certain amount of amps to the blower motor & you may be using wiring that is larger, or connecting directly to a power supply that would make even a weak motor work by providing much more amperage than the vehicle usually does..

You can generally note that a worn motor doesn't turn by hand as smoothly as it should, causing the need for maximum amperage to get it started, tough to do in a car when everything is cold.

I suggest a Vehicle specific manual to aid in troubleshooting if you are unfamiliar with removing those components.

good luck.

Electric radiator fan won't come on when engine gets hot


By pass it. remove wires from fan leaving enough wire to splice onto.Run 2 wires 1 to ground and 1 to a power source in fuse panel that only has power when ignition is on such as running lights . this by passes fuses and relays and assures your fan is running if your vehicle is running.

Cooling issue


Sounds like somebody installed an aftermarket fan switch. Look at the engine side of the radiator and see if you find a probe going into the core itself. If there is one there, follow the wire going to the probe and it will take you to a control box with 2 wires going to it and a small knob. If it's there, one wire will be going to the cooling fan and the other will be going to a power source. It may not be plugged into a power source. While it's running, do you see bubbles in the resevour? If you do, you may have a leaking head gasket causing it to overheat.

NISSAN 240SX A/C PROBLEM.


HI,
Yeah have the voltage to the compressor checked!..By turning on the A/C when hot (and not working),Add a test wire to the 12v output of the A/C relay, to "boost" the 12v amps/voltage going to the compressor clutch. As soon as the test wire touches a strong 12v source, the clutch immediately kicks in. Remember that 12v already existed on that wire, but a stronger 12v source helped give the clutch the extra kick it needs. Thank you!!..Hope this helps you out buddy!!.. :)
