I always start with basic stuff first.
Have you checked battery’s?
PF126F29 is a battery fault code. A dead or low Aux battery or main battery can cause all kinds of issues on these cars.
Dealer should have checked that, but you never know…
Are you saying you a need the wiring diagram for the AC?
(edit: see attached PDF’s which may help)
