The wiring harness between the truck body and the rear driver side half-door (extended cab) passes through a flexible rubber housing. The pair of wires to the seat belt tensioner (part of the airbag system) were broken completely in half mid-way through the rubber housing from normal use of opening and closing the door. Airbag light on dash stayed on permanently which prompted me to locate the problem. Only found it because the radio speaker in that same door had stopped working as well. Found that it had broken wires in the same location along with the airbag system wires. This problem is well documented in online forums as many Colorado owners across many production years have had the same issue.
