Just started today for some reason, in position 3 and especially in position 4 the highest setting it sounds like you are rinding in a turbo prop commuter plane. I used it yesterday with no problems, then this morning it just starting sounding weird, exactly like a prop plane, somewhat of a fluttering roar if that makes any sence. Anyone have any ideas of what it could be? All I have tried is hitting it, unfortunetly that did fix it.

Pull the motor out and see what's going on. Pretty easy to remove. 3 screws & unplug.

Wow that was easy to remove. When I first gave it a once over, I didn't realize that it came out that easy. Anyway, apparently it had sucked a napkin in there, that's what was causing all the ruckus. All is well once again till the next trivial problem. Now I guess I see why what's his face is moving over to the Ford forums...

There ya go! The ol napkin in the squirrel cage trick. Have not heard of that one before.

Dang, mine started doing the same thing the other day, guess I need to pull it out and check for something stuck in it.

Mine did that and I found a airflow door in the fan.
