Welcome. Put the bat away, anything can be fixed.

The service indicator sounds like it is malfunctioning. That is probably a dealer item- it should move one bar approximately every 15000 miles/24000km or so. (I think my math is correct)

As for the AC- does it still work- does it still produce cold air? We need more information to help here.
