OK I'm going to change the blend door actuator next week. Getting too cold out here in Jersey to have Ac blowing out vents all the time. I've read all the "How to" articles I can find on this site. My question is what do I need to do to reset the actuator. There was a good article on it but can't seem to locate it anymore. And should I disconnect the negative side of the battery when I change the actuator? Sorry if this question has been asked 100xs before. But I can't find a procedure anywhere on this site. Thanks for all the help.
