Hey everyone, I am having an issue with getting heat in my 2004 titan.

The coolant level is fine, the flow valve seems to be working properly. Both hoses coming out of firewall are hot when vehicle is up to temp. When I turn the knob in the truck to call for heat, the air will get warm at best.

Any ideas are welcome. Thanks!

Check the operation of the blend door. That is the damper that controls the amount of air flowing over the heater core. If it is not operating fully, you would not get heat. Also, I have seen the knob on the temperature control reohstat strip out. The knob would turn, but the reohstat would not move. Will the knob change it to cold?
