Question about 2006 Nissan Pathfinder
I have a 2005 Nissan Pathfinder with 50K miles, Heat comes out of trhe vents only when I press on the gass or I am moveing. As soon as the truck is idle the airflow slowly gets cold again.
2006 Pathfinder LE heat flow problem. 60k miles. The A/C front and
rear blows cold air even at warmest setting unless the vehicle is
moving. When the vehicle stops the air in the front goes cold again.
Side note: the rear air stays cool whether the vehicle is stopped or moving.
I am having/had the same problem. My rear heater has not worked the last 2 winters, still trying to figure that one out. But I think I solved the front heat problem myself. The heater was blowing cold air while idling and hot air when the car was moving.
I jacked up the front of the vehicle, took the cap off of the reserve tank for the radiator, turned the car on and ran the heat (AC off) for 15 minutes. This is supposed to release any air bubbles in the coolant system and I did see air bubbles emerge as I was watching (this might be normal occurance, I'm far from a mechanical expert). Anyway, this did not immediately solve the problem, still blowing cold air as it sat there idling after 15 minutes. Dejected, I put the cap back on, lowered the vehicle and resigned myself to taking it to a dealer.
But a funny thing happened the next day, the coolant level was a lower (no leaks on the floor) so I filled up, and sure enough, when I started the car and let it warm up a little, hot air started coming out of the heater!!!
As far as my wife knows, I fixed the problem for the price of a bottle of coolant, so I am a hero...but at first I thought it didn't work. Here we are a month later and still blowing warm air and haven't had to replace any more coolant...the internet is a wonderful thing!
Hope this works for you, and I hope I can figure out my rear heater problem as well.

Change your thermostat and check the water level in the radiator. If it is low on water this can happen.
