Could be the bearings in your alternator have gone dry and your alternator is about to quit out on you. I had a friend with an 01 altima and we could always hear him coming before we saw him because of this very problem. Changed the alternator out and noise went away. Thanks for using FixYa!

SOURCE: 97 Nissan Altima AC/heater fan only works on highest setting

Sounds like the blower resistor module needs to be replaced. Could also be the switch.

My ac is not working I have a Chevy Tahoe 2005 the fans won't turn on either .


Hi Maria , The A/C system wouldn't keep the fans from running but none working cooling fans will keep the A/C from working ! This is a fairly complex system if your not familiar with this sort of thing ! I will add the description from the factory service manual.
Cooling Fan Control - Two Fan System
The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood fuse block.
During low speed operation, the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the low speed fan relay coil, closes the relay contacts, and supplies battery positive voltage from the low fan fuse through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the cooling fan s/p relay and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM supplies a ground path for the high speed fan relay and the cooling fan s/p relay through the high speed cooling fan relay control circuit. This energizes the cooling fan s/p relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the high speed fan relay coil is energized closing the relay contacts and provides battery positive voltage from the high fan fuse on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed.
Do you have a check engine light lit ? The thing to do would have it check at the dealer or a ASE certified repair facility ! They could hook up a advanced scan tool an diagnose fairly quick ! Or you could find a wiring diagram an try testing with a volt meter yourself ! But watch yourself so you don't short out the PCM - engine computer !

My 04 Altima 2.5S AC compressor wont engage, I took it to an AC shop and he told me he checked the pressure and everything is ok... no leaks. the compressor is not getting any power as well as the radiator...


You would need a shop manual for the wiring diagram for the ac to troubleshoot it.
There is a low pressure switch and a relay involved that could prevent the clutch from getting power. The radiator fan runs when the ac is running and high pressure is above 200 psi.

Ac refridgerent fill port


The A/C Fill port is the low pressure service port on this diagram;

It is located on the larger diameter aluminum tube coming back from the evaporator and firewall, to the A/C compressor. The fitting will have a taller skinnier cap on it, that may be blue or black. Not red. The R134a refrigerant cans will not connect to the high side port. This is good since the can could potentially explode/vent causing a sort of instant cryo frost bite to exposed skin. I recommend wearing gloves when recharging A/C sytems, especially if you are new to refrigeration systems.

Ask away if you have any more A/C questions or need help with charging the sytem.

The heating/AC fan only runs on the highest setting on my 2000 Chevy Venture. My 1998 Olds Silhouette (sp?) ran all speeds but high. The fuse box has a seperate circuit for heating/AC fan high vs. the...


There are two types of blower fan speed control. One uses a rheostat, and the other one uses electronic circuits. The speed control is atually located on the blower fan housing. It is fastened with two screws. The rheostat kind uses nicrhome wires(same wire used for heating element such as a toaster etc. The more wire wound around the mica material( anyways a mica is a heatproof material), the greater the resistance and therefore the slowe the motor will turn. The electronic kind uses a transistor, and works very much like the speed control on a cordless power drill. The transistor gets pulse from another electronic device and this pulse is modulated by the control knob in your dash. When this transistor gets messed up it gets shorted. This results in having high speed at all settings. The rheostat kind mess up when the nichrome wire gets burnt out and you end up with may a fan that works only on high, or maybe wroks only on medium and high vice versa. So the problem is the speed control mounted on your blower fan housing. If you want to know how to test them let me knw I will show you.
