Which fuses did you check? The maxi fuses near the expansion tank? The 30A fuse in there only supplies the fan - nothing else. As you have no aircon light you should be looking at Fuse F13 in the main fusebox inside the car. Easy to check in another way - turn the Ignition key to 'MAR' and check to cigarette lighter. If that works, fuse F13 should be OK.
If the fuse is OK, turn the key to 'MAR' again and turn the direction control ( screen, footwell, face vents ). Can you hear the motor moving a flap? Press the recirculation button. Do you hear a flap being driven by a motor? Repeat for the cold/hot control.
If you don't hear the motors going, I'd look at the ECU. If the motors do work, you're probably looking for a dead speed controller.
Hazards : The evidence points to there being an alarm. Nothing else would flash them. I suspect you've pulled an alarm supply fuse and the alarm thinks it's been tampered with.
