How to know if your heater flaps are closing fully?

[A1EK]

Quick question on heater flaps and how to test.

I want to know if they are functioning properly when closing off the cold air when the heat is on high?
I can hear the servo motors moving but sometimes they appear to hunt a little. I also noticed that the right side vent near the door seems warmer then the centre vents at first when I start the car, but when the car is warm they eventaully all feel equally as warm.

I know the best way is probably to remove the glove box and open up the servos but just wondered if there is a trick to testing them another way?

You can view the flap angles via diagnostics but I think that is what the flap angle specified to be rather than what it actually is.

The motors are known to fail, Also the control panel has issues causing flap problems

I have a bluetooth OBD-2 if I download VCDS Mobile will this tell me? I may just stick my endoscope camera inside the vent and see.

Doubt that bluetooth thing will help. Endoscope is a better plan.
