This time, I have a noise sounds like fan blade is hitting something. They say it was a leaf in the duct and they blow it out; but suggest me to install a cabin filter, charging me $70, since this car doesn't come with it.
I allerge to grass, not a serious type; but I do. So I just OK with it, hoping no more episode of vent system come further

Tint film

BTW, I bought tint film from Walmart (10) and plan to install this weekend. It should work great with my Xshade

my 01 sentra xe was a base model and didn't have a cabin air filter either. i would occasionally get a few bits into the fan blades, and once there was a mouse! that made the fan wobble and smell a bit until i got it figured out. was able to access it myself fortunately. so i recommend getting the cabin filter if it is possible to fit it to a car that didn't come with one. and get it aftermarket if you can hope it helps.
That reminds me, time to change my cabin filter!!! Two years ago was less than twenty bucks

I had that problem before.

The paper went down to the AC fan from the dashvents.
