Have you got Coolant in the Radiator? Low collant levels will cause cold hair to blow through the vents becuase there isn't enough warm coolant getting into your heater core. So it will just drag cold air in from outside. Check the Radiator before you start your car next. (DO NOT CHECK IT WHILE THE ENGINE IS WARM! or you'll be making a trip to the hospital ;) ) That, or your thermostat might be stuck... but on a car that new... I would hope not...
Definately sounds like a coolant transfer issue. Either no coolant or the thermostat is not working correctly. I would have the thermostat changed and the system flushed. Also, make sure they purge the system of air as this can cause engine overheats. I've also read on a couple of other message boards that the radiators fail often on these cars. I own a 300m and am going to change mine out due to a leak on the passenger side of the radiator.
I have a Chrysler 300M had the thermostat fixed on it,change coolant, put antifreeze in it and it still blows cold air what could it be other than those thanks
I got 99 Chrysler lhs the heater blowing cold air what's the problem you no
It's your cooling fans when they go out the hot air will turn cold. When you are driving the temp drops from the wind entering the radiator from the front grill of your car
low coolant causes no heat at idle or blockage in cooling system.
Just ran into the same problem with my 2004 300M, after installing a new battery. Online research reveals that it is probably the automatic temperature control actuator that is not opening the vents for the warm air to enter.
