Why does my Nissan Frontier heater blow cold?
2012 Nissan Frontier SE. Coolant system drained and filled 6 months ago. drive the front end up on ramps,open the radiator cap, fill the radiator and let it sit and the air will migrate up to the radiator and escape from the open cap. you might need to run the engine to circulate the water if it takes too long for the air to escape.
When does the car heater blow cold air?
I have 2006 VW beetle with the 2.5L engine. Once the engine has warmed to operating temperature, and I am driving it around, the heater works great. As soon as I stop at a red light, or am idling for any length of time the air coming out of the vents begins to lose temperature until it blows cool air.
Why does my water heater blow cold at idle?
Be sure to get all the air out once its flushed or it will have air in your cooling system. I did flush mine with straight water out of garden hose a few times and can now get better heat when at lower RPM’s but still goes cold at idle.
What to do if your heater is blowing cold air?
If the heater starts blowing cold air again, repeat the process (I’ve never had to repeat). It there still is lack of heat issues and the mode doors are working properly and the coolant is reaching proper temperature, then I would replace the heater pump. Also agree with low coolant – but why is coolant low?

What’s the temp of a car heater at idle?
I bled the coolant system as much as possible, was able to get some air out and top off the system. It warms up quick and stays at a steady temp, but heat still blows cool (maybe a little better…). It blows at about 70 degrees at idle (an can melt your face off while driving).
