I am not sure how there is a correlation between fixing the AC and the fuel door but I would certainly take back to the dealer and tell them it stopped working since the AC repair and you want it to work correctly.I took my Niro to the dealership to have the A/C fixed. It was a long drive. The A/C is fixed now. Yay! However, my fuel door no longer opens when I push the button by the steering wheel. I think they forgot to plug it in when they put the dashboard back together following the A/C repair. See the attached picture.
Where does this plug in? I'd like to open my fuel door without having to open my trunk every time. Thanks!
