It's doing it again. At least now I know how to fix it (hopefully) but next order of business is to get a whole new latch assembly. I'll call dealership tomorrow and find out how much one costs. Does anyone know where else I can buy one?
Besides a pick your part junkyard
You know, those latches are very simple, so the problem should be obvious when you remove it. If there is nothing obvious, it could be a binding issue. Maybe just removing, greasing, and re-installing will fix it. Perhaps those can be adjusted, like a sticking door hinge, to relieve binding. Thats what I would try first.
