Sounds as if the fans behind the vents need to be re-oiled. How about spraying some WD-40 on them? Worried about stinking up the car, though. Obviously, I'd probly have to pull out the vent covers.

 

Same problem here. bump for the answer.

 

bump bump....

Most likely is a bad blower motor. The symptom is noise at low fan speed, loudest at speed 1. Noise typically goes away at speed 3 or 4. If fan is left at speed 4 for about 15 - 30 seconds, then no more noise (for a while), even if fan speed is set back to speed 1 or 2. Noise is also louder in recirculated mode.

The only fix is a new blower motor. Nissan has a TSB to put a plastic cover on the motor to reduce the noise. Don't waste your time with the TSB. It does not help at all.

Note: I took the blower motor apart to reoil it. Did not help with the noise.

 

how much for parts and labor to get that fixed??

 

Same thing happened to me....ended up being the belt needed to be tightened up a little bit

 

Nissan OEM part is about $130 + $13 shipping (www.nissanparts.cc). Very easy to install yourself, about 30 minutes.

 

Same problem here. I took it apart, re-oiled: nothing. I can't justify the $$ for a squeak, though. I tried packing foam around it, etc. but to no avail...
