Fan noise when on A/C is on (sounds like a ticking). Noise is louder and more intense with fan at higher speeds. I have been told by mechanics that it is caused by something in the fan housing like a leaf. Cleaned out fan and ducting that I could reach with vacuum and pressurized air. I also replaced the in-cabin air filter but still have not fixed the problem.
remove the blower motor, the debris is most likely stuck in the squirrel cage fan
I had concluded that my 2000 Max SE has no cabin air filter. I have never seen one in a parts book, and neither the Haynes manual nor the Nissan factory manual mention it at all... Do all models have one, just the GLE , or...? My blower made a similar noise; I removed the blower, and the motor was slightly rough. Replaced with a salvage unit - now its silent!

My maxima is an SE. The in cabin filter is located next to the fan. You have to remove the glove box in order to access it. I did take out the "squirrel cage" fan and clean it out before posting this but still have the noise when the fan is on.
