Hi guys. Sorry to say I'm the wrong person to get involved with heater boxes and actuators. Those are kind of a specialty area for HVAC, (heating, ventilation, air conditioning) people.
I did want to add one comment though. We had a very high-level trainer travel to our community college once a month from another state, and in one of his presentations he said as far as having "customer-friendly business practices", meaning looking out for customer satisfaction before profits, the top three in the world were Hyundai, Toyota, and Chrysler. At the bottom of the list was GM, BMW, and Volkswagen. Hopefully that will make you less upset with your car even if the mechanic didn't fix it right the first time.
