Climatronic 80 b4 buttons

[gabrielm]

need some help with the climatronic on my avant 80 b4.

to operate the buttons I need to push hard.

the funny thing is sometimes i just touch the button and it works.

how do I remove and clean the contacts?

Tks

It's not that the buttons contacts are dirty or need cleaning. The connection between the front panel and the main circuit board has a poor connection in it which is why sometimes you can press lightly on the buttons and all works as it should, when you're pressing hard you're moving the front panel with respect to the main circuit board and making the connection work again.

I suggest you take the climate unit apart and resolder the ribbon cable and connector pins that join the two.

The fascia surrounding the aircon controller just prises off, to refit you gently push it back on. Use a plastic pry tool for removal to avoid damage to the fascia. The CC head is held in with two screws.
