Vent rattle noise

Vent rattle noise
In the summer I usually drive with the windows down all the time, unless it is raining... like it was yesterday. I turn on the vents and I hear this rattle-ish noise coming from under the dash on the passenger side. Maybe it's not a rattle, more of a repeated soft clicking sound. If I turn up the fan all the way, it gets louder... The noise is there whether or not the AC is on, AND it is there whether or not I even have the lower vents on. I can turn on just the upper vents and the noise is still there.
I'll probably investigate it this weekend, but first, does anyone have any suggestions? or a similar problem?

RE: Vent rattle noise
OK, I did a little investigation. The noise isn't coming from the vent, it's coming from the blower motor. And I was wrong about the speed -- if I turn the vents up all the way, it gets louder AND faster. I don't know if there's anything actually WRONG witht he motor, because it is still running and it's pushing a lot of air. Do you think I can take it apart and see if there's something in the fan blades? is that a good idea? Maybe just clean it out? How would stuff get in there anyway?
thanks!!
thanks!!

Sounds like something got in throught the fresh air vent from outside and is stuck in the blower fan. Time to get in there and clean it out. I have had pine needles or things like straws that some how got into the blower from outside and were clicking on the fan blades. Depending on the car, it's an easy thing to fix or an all day job of ripping the dash out to get to the blower motor.

I found the blower motor, it is right under the glove box. 3 screws and it should pop right out (I hope). I'll probably get to it on the weekend. There better not be any dead animals in there [sm=insomnia.gif]

Diagnosis: LEAVES! Lots of them!
Note: you do have to take the kick panel off to get the motor out. It's best to remove the panel before you detach the motor and it is half-hanging, half jammed in there.
