2006 Equinox LT Liftgate Locked Not Openable
 

2006 Equinox - 35 k miles, grocery getter. New ACD 47 7yr battery last year.
New cr 2013 batteries in the remotes. Normal lock up functions work on
other 4 doors and alarm woop woop. Lights go off and on as usual.
OCCASIONALLY driver door will not open after stopping car and placing in
park, when you normally hear the other doors lock/unlock.
Went to the supermarket one day. Loaded with lots of frozens and when we
got home, had to lay down the back seat to work.
Time to pull the interior panels ??
