heating

Hello, whenever I press the button for the defroster to come on it turns on for about half a second then goes out. Another thing is, and I'm not sure how the HVAC on the Daytona's are setup, when changing which way I want the AC/Heat to come out, it just stays on defroster but I don't think...

yep i got the alternator fixed now it my gage says it is overheating but i think i have air in my cooling system and i dont know how to bleed it if any one does it would be nice so i can get to work today one thing after another
