The wiring for the airbags runs through a hinge in the extended cab doors. I don’t use my rear doors much, but I would say that I use them a normal amount. Regular opening and closing of the door will cause the wires to break, thus making the airbags inoperable. Normal use of doors should not cause your airbags to not work.
