Why do I have cold air on my 2008 nitro r/t

Asked by Feb 14, 2016 at 02:46 PM about the 2008 Dodge Nitro R/T 4WD

Question type: Maintenance & Repair

I get cold air when it's real cold, below 20 degrees, it's fine when it's warmer. I
got the heater core replaced a year ago and it was fine until now. Any ideas?

May need the thermostat replaced. Make sure the engine is getting to operating temperature. Also check the coolant level.

Thanks, checked my levels, looks a little low, will know in the morning.. Fingers crossed

Not hot air, just warm air with the heat on, cool air when the defrost is on, thermometer is registering half way between cold and hot.. Any ideas?

Sound like it is showing normal. First check to see that both heater hoses are getting hot. If so, then probably a plugged heater core that would need to be back flushed, or the climate control door is not adjusting for cold to hot. Blends in the outside air to mix for proper cabin temperature setting.
