I have a 05 malibu LS suddenly there is no heat. The fluid level in the radiator
is normal, no smell of antifreeze, the windshield has never clouded up. The veh does not run hot, everything runs perfect but the heat. Can anyone give me some ideals where to trouble shoot this?

Turn the veh off and on again - it's a BCM issue.

You need to supply more information are the heater hoses hot? Do the dampers for floor heat and def. work. Is your operating temp normal? Without basic information any answer is a guess at best.
If the hoses are cold purchase a manual at an auto parts store and find out where the control valve for the heater is located. This should give you an idea where to look. This unit uses a heater control valve which is like a damper on the bottom of the case where the heater core is located. It should have an a vacuum operated unit to move the door. The vacuum control valve should be in the dash.
