SOURCE: 2004 NISSAN ALTIMA 2.5 NO CABIN HEAT..ENGINE AT OPERATING TEMP.

If the engine is not over heating than most lilely it isn't the thermostat or waterpump that is causing the problem. Check the heater hose coming out of the manifold and see if it is warm to hot. Next check the return line from the heater if it is still cold or moch cooler than the inlet, the most possible problem is the heater water control valve if this model has one or possible the core of the heater is plugg with slime cause by some antifreezes setting during the summer months while not being used. If this is the case than remove tihe two hoses and back flush the heater core with water pressure until it runs clear. I have had this problem before and this cured my problem. I also had to flush the engine and radatior also. Hope this help. .

You can't find one, because it doesn't have one.

SOURCE: MY CHECK ENGINE LIGHT CAME ON YESTERDAY BUT MY 2004 NISSAN SENTRA

hi, most of the time when these lights come on, its because of some sort of sensor failure. if you are not experiencing any noises or tapping in the engine compartment, this is only a failed sensor. you will have to get it diagnosed by the computer to know what specific sensor it may be. i suspect maybe a O2 sensor or egr valve. this is minor but, you Will need to get this repaired if possible.

Have a 92 Nissan sentra and the heater only blows cold air


let the engine warm up to operating temperature. turn on the heat full blast. feel the two hoses going to the firewall to the heater core; if they are both hot, then your problem is in the heater box or heater controls. if one hose is significantly cooler than the other, then you have a clogged heater core and you can replace it or try and backflush it.

I have an 1996 Nissan Sentra GXE i live in ND and the heater only blows luke warm air while at full operating temperature. I replaced the thermostat and flushed the heater core which seemed clean....


Sounds like it's the air control flap which determines the mix of heated and fresh air. This could be vacuum controlled or manually with a cable.
