Electrical Nightmare

[igloo0001]

i had the car looked over by a mechanic whom had a computer, results i need a new computer and multifunction switch,
no wires are burnt the smoke came from the instrument panal it looks fine you can smell something had burned but everything on the panal works , i did the self test holding the trip button down i get (bus b0 panel input open airbag ) any help with that is great .
i get no p0000 codes maybe due to the damage computer might bring it to the dealer let them just deal with it..

Any advice is helpful thanks again
