Here's what I was looking for....

The sound is coming from the metal faceplace which covers the wire spool around the spindle of the fan. the faceplace must be balanced properly because it holds in place the spindle which is rotating for the fan to blow. when the faceplace is off balance by one of two screws that holds it in place, the fan ticks like a MF'er....as you balance the plate, the tick goes away and is as quiet as a mouse.
#1 I took my glove box completely off making sure to release the springy thing first on the right side towards the passenger door and then just popped her out.
#2 I then got out my trusty ratchet with a 5.5mm socket and removed 3 screws on the underside of the blower....the fan will slide out easily. leave the wires attached (be careful as the fan is still runnin' lectric)
#3 let down the door that holds the cabin filter in and remove filter. now you can reach up in there and see if any of those mysterious leaves are present. blow it out with your air compressor or just root your hand around in there to get anything out.
#4 hold the black plastic fan housing in your hand carefully and reach over and turn your a/c on the low setting (BE CAREFUL as that thing is quick to get away from you and can take a nub off pretty quickly) make sure you can hear the sound coming from the assembly in your hand. If so, move to step #5.
#5 remove the covering with a phillips screwdriver (4 screws - i think) and remove that cover to reveal a silver metal cover with TWO (2) lubed screws. THESE ARE THE SCREWS THAT MUST BE BALANCED. Take a pair of vice grips and grab the black housing with them so you can get your hands away from the moving fan and so you can hold it steady. then use your phillips screwdriver on one of the two screws and notice how you can make the sound/tick worse as you tighten one of the screws.....too tight and the fan slows down and/or TICKS, too loose and the fan slows down....(spindle getting in a bind).
There is a point where the fan will turn fastest
and the sound will disappear
magically. You'll see what I'm talking about once you're in there adjusting the screws to find that perfect point.
#6 re-assemble and enjoy!
I hope this helps a few people that have this ANNOYING sound!
sometimes it just takes getting pissed off.....damn delphi.
Why didn't they have metal stoppers under those screws or not have the spindle held still by a moveable plate......argh....
I think that over time, those screws are backing out at different rates, which makes the spindle bind up and/or ticking sound occur......
