Hi. how are you. When I turn on the AC my fan making a noise is it time to replace or any thing i can do with it. With out AC its work good. Thank you.

While idling, your fan usually doesn't spin (unless it's been sitting for a little while or it's hot out) until you start up the A/C.

Is your fan making an unusual noise?

when the AC goes to MAX the fan will spin at higher speed so it will have louder fan noise. if you turn down the AC to a lower level the fan will slow down.

I will test it.

Here is info from my post on this issue.
Auxiliary Fan, Control Unit – A few months ago the Radiator Fan was make some noise. While in the shop for oil change, they said the Auxiliary Fan Assembly need replaced for $1200. I checked it out myself and found that it was only the electric motor going. It appears that you can only purchase the complete assembly. I took the motor apart, and could only replace one bearing. The other bearing is on the end with the pulley, and it looks like its molded together and I can’t get it apart. So, I searched the Internet, and found an aftermarket AFA for $350. Took that motor off and used it. This works fine. It appears that the Auxiliary Fan Control Unit stopped working. also Why? I tested the AFCU with my voltmeter and it had 12v in, variable control voltage in, but 0v out. It appears this shorted out (stuck open). I beat it with my hammer, but no help. I have not opened it up yet. Has anybody done this? I currently have the motor connected to a relay. Now the fan runs all the time, at 100% and it’s loud, as in airflow loud. This really moves the air. I located a new AFCU, but $170, ouch again. Is it common for the AFCU to go out also?
Danger note: I connected the relay to a fuse that was 12v only when on. Mistake was not knowing what the fuse did. While I was driving 65mph the car shut off. I safely pulled off the road and seen the fuse that I tapped into was blown. Replaced the fuse, move the relay 12v to a different fuse, this one is working fine. On the relay I do have the 12v for the fan connected to the fans 60amp fuse. This is just the 12v control voltage.

To test further, (with car off and cool, you can also pull the 60a fuse if you want) pull the AFA away from the radiator and take the belt off. Spin the fan with your hand. Noise? Mine did not make any noise, so the fan was good. Start the car, run the AC, AFA motor ran and it was noisy. Motor bearing going out, so I did the above task.

are you talking about the interior fan inside the cabin??? or outside near the radiator? my interior fan would squeel sometimes. It seemed like when it was cold outside it would do it more...then eventually it would go away. it was the bearings in the interior cabin fan that went bad but starmark war covered it
