You probably have a drivers door lock problem. The alternating red green lights indicate a problem.

The activity in #2 makes me think the problem in #1 is the drivers door.

In your AC problem, check to see if the compressor is on, or if it is just the blower that isn't working. Without a wiring diagram I have no idea what that fuse does but the common problem in 140 cars is the blower regulator. The compressor would be on though and if you drove you would feel cold air forced ventilated into the car.
