I need some advice on my heating control panel. I have a 2003 a3 1.8 sport. The heating control panel looks alot different from the ones on similar a3's. The rear screen heater and recylced air buttons dont push in or do anything. Are they just there for show and they should be located elsewhere? I am starting to think the previous owner has removed the old heating control panel and replaced it with the ones shown in the pictures. Advice on how to get rear screen heating on please!

 

Bump!
