I need to remove the headliner on a 2013 ford fusion
@teryn , Cliff, before removing the headliner are there and interior dome lights in the vicinity of the antenna. Some times the antenna base nut can be accessed by removing the dome light. If not accessible there is a write up at link below on removing the headliner. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. http://www.fordfusionclub.com/213-electr…
