The 2 fans you have are not both for the radiator, left hand drive, if you face the engine the fan on your left is the radiator fan and on the left is the aircon fan.

1995 nissan altima se fans not working

If you mean the cooling fan on the radiator, the computer grounds the fan relay when the fan is needed. If the engine temp reaches 220 degrees or you turn on the ac and the fan does not come on, check the relay first.

I have a 1995 nissan altima.I changed the motor on it twice .The third motor I got from a 2000 altima ,same motor different year. Anyhow when running the motor,if I plug in the fan switch the fans will not...

You have quite a situation. It sounds as though the Coolant Temperature Sensor is faulty. That sensor will control the temp gauge in the dash as well as control the cooling fans when necessary. As to why the fans are constantly running whether the switch is on or not would mean that there is power to the fans bypassing switch, possibly from another connection in the harness. First off I would try replacing the fan relay, it may be stuck closed, just switch it out with another of the same type connection from the fuse box to see if there is any change. If that doesn't work then I would check to see if the wiring from the coolant temp sensor and the fan switch run through the same area of the harness. Its possible that you may have a short circuit at that point. That may possibly explain why the gauge is reading hot when the motor in fact is not. Hope this helps. Good Luck.

93 auto matic mitsubishi eclipes gs and it turn off by its self and then it takes some times 2 or five hours to start

hi to me this sounds like its the oxygen sensor (or lambda sensor for its proper name) The reason i say this is that if your car runs fine from first starting or cold but then starts playing up when the engine is up to running temp then this points towards the o2 sensor due to the fact that the sensor only starts working when the engine is at a certain temp so if this is when your car plays up then this is what i would get looked at first.

Let me know how you get on or if you need further assistance ok

I have a 96 Nissan Altima GXE with the 2.4 liter motor that has a problem code coming up P1401 do u know what it is

this code is telling you something is wrong with your EGR temp sensor circuit, this is due to an extreme low or high voltage detection from the sensor by your cars ECM computer. check the harness connections or check/ place your EGR temperature sensor, this should solve your issue, thanks

No fan on and engine hot 95 Nissan Altima

for the fans check the ect, engine coolant temperature sensor. located on the thermostat housin, this tells your computer when the temperature is at 228 degrees f which turns on your fan. if the gauge is reading hot it could be either the temperature sensor on the radiator or you have an after market radiator cap(checkers, autozone, pep boys) whatever but the dealer cap will make the temp. read right. the tach is gonna be your crank sensor or cam sensor and your shift codes should be your tranny sensor, not the shift nuetral safety switch.

Radiator fan problem

Call up the dealer and ask what commands the fans to come on once the car reaches operating temp, on alot of imports, there is a fan control box of some sort that actually sends the sig to the fans to come on.

If it's the temp sensor and the computer tells the fans to come on you could be looking at a faulty computer.

This would deffinetly be worth taking to the dealer to diagnose so that you don't keep wasting your time and money chasing a ghost.
