Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,In most cases the problem you are having with passenger side temp control is caused by a failing blend door actuator . Any reset you could do would have reset when you disconnected the battery cable. The fix in 99% of all cases requires replacing the blend door actuator. If you need replacement steps I can provide them for you.
The good news is the RH side is fairly easy to access and replace. You can get to it through the glove box opening. See the factory steps in the link below.
