I've been hearing the dreaded blend door actuator noise for a few months. It has steadily gotten worse so I stopped by the local Ford dealership on the way home this afternoon to have them listen to it. The service writer sent a tech out to check it out and he was "very familiar" with the problem. He has pulled many dashes to replace them. Mine is scheduled for next Wednesday...he says 4 hours and quoted me $518.00....this sounds decent compared to other posts I've read. What's everyone else think?

The actuator is in place to move the door from one position to another and blends both hot and cold air to vents according to your setting on the dash. This happens in both heating and cooling mode. When the actuator goes bad, it creates a steady "popping" or "clicking" noise under the dash (near the glove box) and is mostly annoying. Ford evidently purchased a bunch of crappy actuator's and the Super Duty trucks have this issue often.
