In the interior on the phase 2 there is a small plastic 'grid' in the dash, just to the left of the center console. What is behind it and what does it mean when it makes a cracking sound lol!?

Isn't it the inside/cabin temprature sensor for the climate control.???

Duno sounds about right, heating seems to work fine. Air con dont work but car was stood for a few years so thats to be expected. Only just started crackling too and the air con aint worked for a while..
