How to replace the aircon indicator bulb?

[Robbi Blechdose]

Hey everyone,
I finally got myself a K11: A 2002 model with the 1.4l, CVT and aircon.

I believe the aircon works, but the bulb isn't lighting up. I've searched both google and the factory service manual, but found no mention of how to replace it.
If anyone knows I'd be grateful for the help.

I have never fiddle with the AC switch but is all built in on the heater control panel so im pretty sure you gotta take the hole panel.
The light seems to be built in with the double switch (i assume by how is represented on the schematic).
The switch gives 12V on the output on 2 pins, one for the thermo control amp and the other to pin 76 on the ECU.
I would check if those pins are receiving 12V indeed to check if it really has working AC (maybe it has a blown bulb and empty circuit).
Check this if it helps a bit more.
