I don't have access to the TIS at the moment, but looking at the ETK, it doesn't show any bowden cables on the manual aircon panel, so it 'looks' like it's all electronic.

I'm certain it won't do any harm to slowly prise the module out, as even if there are bowden cables attached, similar to the upper fresh air vents, there will be slack to allow them to be attached/detached.

Just do it slowly and carefully. Once you have overcome the resistance of the clips, it should slide out easily. Any resistance needs to be carefully checked, but I'm sure you'll be fine.
