Squeaking from behind glovebox

Hello,
Recently I started to notice my '09 was making a noise from behind the glove box. It seems to randomly come and go but is high pitched and loud enough for me to notice driving and is slowly driving me crazy. Anyone have problems similar to this? I've looked online for solutions but cant find any with my specific problem and don't want to go digging through things in this weather with no garage.

Thanks,

In the engine compartment pop the cover off the battery and look down behind the battery. You should see the top of the blower fan. Although it is a sealed fan-motor assembly spray some WD40 or your favorite lubricant on the top of the fan. If enough lubricant seeps down the shaft and lubricates the bearing the noise will at least temporarily stop. The interior may smell of lubricant for a day or so but at least there will be no squeal. You’ll eventually have to replace the fan-motor assembly. Simple task and there are a couple of good how to articles with instructions in the forum.

I actually got a bit of this today. Had to do with the fan. Thanks for your comment, I'll look into it when it's spring lol. Usually it goes away when the weather warms up though, and I forget about it haha.
