Hello, and welcome to fixya! The reason that you are able to hear the climate control system and not feel the air coming out of the defroster, is that the damper (this controls where the air is directed when you change the vent selection on the climate controls) is not operating as it should. The damper is controlled by vacuum pressure, and the usual culprit is that the vacuum hose running to the damper is either loose, or defective(usually dry rotted) which will create a vacuum loss. Without the vacuum pressure to operate the damper, you will lose some, but not all functionality of the vent selection. I recommend that you check the vacuum line(s) that run to the damper, making sure that the vacuum hose is connected, and free of defects, like cracks, holes, and that the connections are not loose as hoses can and will lose their elasticity, which will create a vacuum loss. If that is not the issue, I recommend that you remove the climate control vent selector and make sure that all of the connections to the control panel are secure and free of defect. If that is not the issue, you may have a faulty damper (which is rarely the case), and that will need to be replaced. As far as the climate control lights not working, that could be a simple as a blown fuse, faulty bulbs, or even as simple as a poor connection to the bulbs, or to the control selector. I highly recommend that you disconnect and reconnect all of the connections to the unit. When you check the fuse panel, remove the fuse(s) & check for faults and make sure that the connection the fuse is making in the fuse panel is making a solid connection. I hope that you have found this information useful, are able to resolve the issues you are experiencing.
