Chirping Noise From Vent
 

I have a high pitched chirping noise coming from the drivers side vent when the engine is on. Any ideas on what it could be?

I have the same sound, and i think it is the fan... it either needs to be replaced or oiled or cleaned or something, but bottom line is it's pretty annoying!

Regards,

Annoying indeed!
 

It is sooo annoying! I'm just hoping that it is something as simple as the fan...

I would pull the fan out from under the glove box and check to see if you can oil the bearing, it only takes 10 minutes to pull the blower motor.

I had the chirping, its the blower motor, warranty replaced at 99k
