I've been hearing a rattle in my dash, and when I pushed on the instrument cluster the whole assembly shifted in the dash! I don't think it's screwed in at all, just sitting in there. I can also pull the center vent assembly out without removing any screws, so this is just sitting there as well. Does anyone know how the cluster assembly attaches to the dash? Maybe someone with a service manual can tell me what the dash/cluster assembly/disassembly procedure is? It's a 2001 non-Sport. Thanks!
