Rear A/C control Panel sticky buttons fix.

[brcas64]

T6.1 A/C rear control panel buttons sticky causing the A/C to do its own thing.

The cover of the control can be easily removed with a trim tool and the unit unplugged by pushing a small screwdriver or key into the fitting holding the control cables. The unit can then be removed. There are 4 hex screw on the back of the unit and the unit can be taken apart easily. The buttons are a tight fit but can be popped with a trim tool. The bottom of the top button and the bottom of the button below run against a small metal strip. File the top the edges of the buttons and the buttons will run freely. Quite easy to do and took about 10 minutes in all.sorry should have taken more pics. A/C unit controls now working correctly

Thank you @brcas64 I just had this issue last weekend: the rear A/C went into full blast fan mode: a finger nail in the button helped stop it.

A tiny bit of contact spray ariund the sticky button solved the issue with me, until VW could finally source a replacement under warranty back in 2021.
