2012 Terrain Rear Hatch won't open often
I have a 2012 GMC Terrain. The rear hatch only opens occasionally...usually
need to push it many times. This is not a powered hatch. I have replaced the
switch twice (once at the dealer under warranty, and once last year myself) but
now a switch replacement is not helping...the switch is new and I have tested it
with my multimeter and it is fine. What else should I check?
