OK,, winter is coming now and I really should get that heating fixed and I need some advice before I take things apart. The only thing that comes out of the vents is cold air no matter what the settings. Also there is a constant clicking noise thats coming from the air control area. No traces of rad fluid in the car. Also when I got the car those 6 months ago, there was a hose disconnected from a fluid distributor thingy (with two plugs red and green) near the winshield wiper fliud tank, there should be a pic under my user name. Nothing was leaking from it though,, and my coolent level was good. I connected it back right away (still no heat),, not sure if that has anything to do with it but anyway what should be done to fix it?
