On my 96 A4 2.8, the climate control LCDs only work sometimes. They both are either on or off, never one on and one off. I noticed when they are off that if I press hard between them they come on, so it seems like something is loose. When I tried to gently pull off the woodgrain facing around the whole radio and LCDs, it was reluctant to come off. Also looks like the facing has some electrical contacts built into it. Can anyone tell me how to access the LCDs and any ideas on how to fix them? Thanks!
