Successfully made the repair. Some additional hints and tips (these may be overly cautious, but they could help prevent some hiccups I encountered):
1. Go to Pep Boys (or your favorite store) and buy electrical cleaner and electrical contact grease before you get started. Also find an eye glass screw driver (see #4).
2. There are 3 servos, two against the center console, and one up high not against the center console. Unplug one at a time to find the culprit (the noise will stop). My guess is that it will be the servo behind the freon lines because of the heat (that was mine).
3. Take the key out of the ignition, do not return it until the repair is complete (don't want to change any positions).
4. You can remove the servo behind the freon lines with an eye glass screw driver (thin, 2-3 inches long, can twist end with pliers). It's only needed for one of the screws, you can fit a thin screw driver between the two freon lines.
5. Before taking apart the servo, record the position of the plastic arm.
6. Be careful, the clips holding the servo together break easily.
7. Once the servo is apart (plastic arm down) record the position of the motor. There are two contacts at top of the motor, I think it's important to not reverse them. There is probably a part number stamped on the motor, know if it was up or down is probably an adequate guide.
8. Record the position of the big gear with the contacts.
8. Completely clean inside (especially big gear with grease on it) with the cleaner, then reapply new grease. I tried without cleaner and grease and ended up having to run to the store then redo everything.
If you do as I did without these hints, the system will blow hot air on max cool:
1. Set air to max cool before removing keys from ignition.
2. Take out servo, do not record plastic arm position.
3. Rotate motor in servo to reverse the poles.
4. Place plastic arm on servo so that it fits back into the damper lever. The damper level falls to the cool position when you remove the servo. Prove this out by turning air on without the servo, play with the lever and you'll see.
Good Luck. I'm not a mechanic and rarely do this kind of stuff, it wasn't so bad. Didn't want to pay $$$ to hush a harmless noise.
