The rear NS brake light and high tailgate brake light need replacing on my 2007 Galaxy TDi ghia. I cannot figure out how to gain access to either. I have removed a small trim panel for the brake light but am unable to gain access to the "wing nuts" the manual refers to.....any ideas? Similarly the manual suggests using a screw driver to allow access to the tail gate light......I am unsure of what to do.....many thanks for any help! billthedrill
