I had an accident in the front right of my vehicle and took it in for repairs. It took 45 days for the shop to repair Amaizing Huh? Well Now my vehicle liftgate will not open and I get a "Assis Park" Error on my dash. I had replaced the latch motor thinking is will resolve the porblem but it remain not opening. It do not make a noise but the vehicle lights flash indicating button pressed on the FOB. The window on the liftgate opens with no problem. I checked all fuses and its all good. I believe the shop sabotaged my vehicle so I called them to tell them they had made an error. I shop said they will charge me $100 to check plus parts thinking I was that gullible. do anyone know how to trace back and diagnose the power going to the liftgate. It might be a plug disconnected but Im not sure. Any help is appreciated!
