Just to calrify, you want ot get at the climate controls? the console that has the turn wheel the slider and the three buttons?

That's a 5 minutes job if you have the same setup as me. First take out the ash tray, then take out the two vent grates on the left and right. Undo the two scres that you will be able to access once you remove those, then remove the two scres from the air ducts above the console and it all comes out, pull it slightly forward to get at the cables and pull them out one by one, no need to worry they are all different size and only fit into one place.

8 hours? with a different setup maybe.
