I need to replace the antenna base, where can I find the DIY instructions for doing this repair? I understand that the base is attached with a nut but I have to remove the ceiling headliner? Is there a process/photos somewhere explaining how to get access to the antenna mount from the inside?

 

Perhaps this will help

Yes, I already read that and it wasn't helpful - photos would be nice. If the headliner is easily pried away I think I can replace the antenna no sweat. Thanks for your reply!

 

No pics but fair explanation

I remember a detailed post with pics a few years ago but can't find it now

 

My apologies for off-site links...

I just reached carefully under the headliner after pulling the rear 3 clips and removing the rear weatherstrip for the hatch....just be carefull not to crease your headliner.
