Hello, the Tahoe is a 09 and I have seen plenty of threads on other issues but not this. The roof always worked fine till it randomly stopped opening. My wife showed me the culprit, it's a hard plastic belt up in the headliner with tabs on it that looks like it would go over a motor or gear system, that is snapped. Every kit I look at doesn't have anything that looks remotely like this. Maybe that isn't the problem and it belongs to something else but I would at least like to know what the belt is. Thank you in advance.
