Question about 2002 Nissan Maxima

Heater fan noise-'02 Nissan Maxima

In extremely cold weather, the fan makes a loud "almost grinding" noise for several minutes. The noise sometimes ends when you make a sharp turn and/or the motors been blowing for a few minutes (i.e the car heats up). My first thought is that something inside the blowed is stuck or frozen up or that its a vent issue in the heater. The heater itself works fine once you get beyond the noise issue.

    I have the same problem (02 Maxima GLE with 125,000 miles). To me it sounds like something in there just needs to be greased, but I have no idea how to get in there and do that. I hope someone has a solution.

    I have a very similar problem on my 2003 Maxima. Originally thought it was the fan blade, but now I believe it is associated with the dampers. Worse in cold weather with cold engine and seems to be initiated by acceleration or bumps in the road. When it stops, everything seems to work normally.

I had this same problem. It got cold and a mouse built a nest in the fan. I drive the car almost every day and its garage kept. After taking out the mouse and its nest the noise was gone.

Get yoursf a Hanes manual for your car. It will tell you where to look and where it is located. Eventually you can get a code reader from auto zone and the manual will tell you the codes and how to read them wo paying someone to do it

05 nissan maxima making a loud noise when the heater or the AC turns on but the heater and AC works need help


-Depend on what sound like...? It could be loose fan, some object hang in to the fan, or dry leave or may be some thing stuck inside the fan's housing.
-You can open from the inside and check. If find some thing, remove and turn on to find out still any noise before closed.

Good Luck

Noise coming from the rear end of my 2004 honda pilot it really only occurs during cold weather and after it warms up you hear it slightly


When does the noise occur, while driving only, or driving and idle, in gear, or in neutral and park? If it occurs all the time (while driving and at a stand still in cold weather) it could be the fuel pump. If it occurs only while driving, it may be a wheel bearing. Describe the noise (humming, grinding, whirring, etc), and what is the mileage on the Pilot? Answer my questions so I can fine tune my answer. Thanks!

2004 nissan pathfinder fan noise


I had the same problem in my Pathfinder a couple months ago. It's most likely your fan clutch. I had mine replaced, and the noise went away. And it seems that it is the cold weather causes this.

2000 Nissan Maxima sounds like its not shifting into 3rd gear


What do you mean by loud... Loud where??? If noise is from engine, make sure that the mechanical fan clutch is not "locked" (it's supposed to freewheel when cold... if it does not, it will "roar" when driving.
