Question Heater will not Blow Hot Air

Well just a few days ago my heater in the titan quit blowing hot air, it only blows cold air. This happened instantly, not over a period of time. I have the dual climate controls and the fan works fine, ac works fine, but the temp. doesn't change at all from 60-90*. What do you think the most common problem could be? I am thinking something to do with the temp control module or actuator. Anybody got any ideas. Coolant is fine, just replaced raditor cap, engine temp is fine.

Try to isolate the problem by shutting off all controls but the primary and see if you get hot air and visce/versa.

Check the servos that move the damper plates, and the damper plates themselves in the air box for free movement.

The servos themselves are fairly bullet proof, but the chinsey little plastic doo-hicky (technical term) that the rods connect to break easy if there is a jam, i.e. airbox distorts due to high heat.

Neighbors Armada went through this saga last fall. Nissan, out of frustration and my neighbor threatening lemon law, replaced the entire airbox/damper set up.

Where is the airbox/dampner located? Is it inside the dash on the passenger side? Ya it doesn't work under any of the modes, defrost, feet, face, ac on/off, dual/single climate. That sounds like the problem, but Alaska doesn't get high heat situations although it gets actuated often due ambient temperature fluctuations. Thanks

This happened to the wifes 2004 maxima and come to find out there was no coolant in the radiator. No leaks found in the garage or driveway but some how the upper and lower rad hoses wear bad and leaked. It also never ran hot without coolant. I just re-read your post and see that the coolant is fine.

No heat...

A couple things to also consider checking.

1. Coolant level.
2. Replace radiator cap
3. Check thermostat
