When you reconnected the battery, no noise could have been produced by
"flaps" because they are driven by vaccuum, unless the engine was
running....at that time.
You cannot reset electrically the programmer. You can reset the AC
Head...the one with the little buttons , LED's for temperature etc.....
I understand NOW everything is OK ?. So I venture to say that the AC
Head with the battery disconnected, went into some form of reset mode
(not sure about this). When you reconnected the battery, the AC head
sent an "illegal" configuration to the programmer (I am guessing a
little) the programmer and head are both designed to go into a failure
default mode and DEFROST......
So if the head is OK and sends the right codes into programmer and there
are no vaccuum leaks...Don't worry, be happy ! If not please send us
another message to try to help you !
Good luck
