Yesterday, while cutting up carpet samples to line the trunk and saddlebags, I made yet another discovery-the heat vents. All this time I thought those doors were for access to screws for the plastics. That means all this time I wasn't getting heat. They do not open with the knob, I have to manually open them when the knob is showing open. They will close with the knob. So something is hanging up there. When I open them with my fingers I can feel some hesitation. I'm thinking that there needs to be some lube sprayed in somewhere. How do I get to the cable or whatever it is to do this? I'm planning on disconnecting the radio and CB today as they don't work. I will have the center console out and the seat. I also plan on adding my new light bar as well so some of the stuff will be removed, can I access what I need to get to? If it's involved, I'll just leave as is because it's getting to the point I won't need them and save it for if I need to go that far with the plastics. Just wondering how to fix this minor inconvenience.
