I wouldn't think it was too hard. I had my dash out today and after that to take out the middle section where the temp controls are it is just snaps. At least you could pull it apart and look into it. To take the dash panel off you take out the 16 allen head screws visable on the front panel then pull out the snap tabs. Maybe someone else has gone into this a little further.
