it only blows cold air!

Check to see if you can hear the damper opening when you turn the heat to hot and back to cold. Same thing with the heater control. you should hear a thump this is the air deflector moving.. Does ti feel real loose when you move the control. Does the defrost work? Ahh too many questions!
Then again your heater core on this fine vehicle may be plugged, any cooling issues last summer? My bet is on the damper is not moving allowing hot air to enter the vent system.

Similar thing happened to me on my Altima. It just started happening. Everything was fine last year. What I did temporarily was to let the air circulate within the car (press the button with the little car picture) This helped a little but it will fog the car soon if you keep driving several miles so switch for a short time to normal mode. Then after few minutes back to circulating the air. However, I really found out what the problem was. It was very simple. MY COOLANT WAS VERY LOW!! And the core was filled up with air instead of the hot coolant. Therefore the heat was getting generated from air-filled core rather than coolant-filled heater core. Add coolant (to the radiator or overflow bottle). Caution! DO NOT OPEN RADIATOR CAP WHEN THE ENGINE IS HOT!!

Several things can cause this. A plugged heater core, a bad thermostat or air in the system. Have someone open the air bleeder by the thermostat and get all the air out of the system (bleed it). Otherwise the thermostat is the next cheapest thing to replace. Good luck

There are lots of things to check. Two places to start are:
1. Engine thermostat. If the temp gauge is stuck on C, even after driving awhile, the thermostat is bad.
2. Cracked heater core. If the coolant level is dropping, or you smell coolant in the car, then that's the problem.

1. Blower motor is out (no air coming out of the vents)
2. Heater Core is cracked (you would see fluid)

The first thing to check is coolant level. If it's low enough so your heater doesn't work, you're close to blown head gaskets and cracked heads.

We need more info. Is it blowing cold air? in which case its a thermostat or coolant related problem. Or is it not blowing at all, in which case its a fuse, wiring or fan motor problem.
