Nissan almera 1.8 2005 heater stays on

SOURCE: 2005 Pathfinder Heat Flow problem

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.

Hi there, very common on these vehicles, you need to remove the heater cotrols and check that the cable hasn't come out, usually the clips that hold the cables in place break causing the heaters to not work properly, Nissan do modified clips now to stop it from happening, it may need a cable too if its too far bent, hope this helps.

Hi it is either your blower motor relay or your blower motor itself.

the majority of heater resistors are on the heater box under the passenger ide of the dash, on some very few models it is part of the actual ac control panel
