I have read a couple different threads after searching. Some about the air control valve, some about the logicon. My sunroof also will not come back but an inch, like it has no power, but if you press the button like 30 times is goes half way, then it works again. The heater core is good, but the switchs for the heater air do not do anything. The whole thing just doesn't work. Now I am wondering what I need to check to figure out if the logicon is bad or not hooked up? It feels like it is getting no power at all. I also read about the key jiggling thing, but I don't feel that is what it is since the unit does not work at all. Any help would be appreciated.
