I will look for it. Is it a valve that can be opened and closed manually?

@Cam shaftIts a computer controlled part its what was wrong with mine I thought it might have been the heater core but after some research it was not the part I replaced it with now makes a ticking noise so I'm assuming its got some bad gears or something in it but it is currently working

CommentMy titan doesn’t want to blow heat out.
Nissan Titan 2009 5.6 296897 miles
My heater won’t blow heat out and it’s nothing but cold air. I already replaced the heater control valve and still nothing. What fuse do I look for or what else can I do to make this issue stop?

It very well could be the air mix door motor. When you turn the ignition on listen for a popping or clicking sound from behind the dash, that could be the actuator binding as its trying to operate.
Take out the heater control valve, use small screwdriver turn valve 1/4 turn clockwise. Leave control valve out. Mine works fine like this

I have the same noise when I switch from heater to AC or switch defrost to another setting. I was told its a vent behind the glove box.

Imobilizer seems to be bad. Had a smith come and program a key but problem persisted. Do i have to relearn or program immobilizer after i replace it?

Check your tail pipe. If it’s hanging or missing there is electrical harness that melts and creates a scenario but check that first it’s a known problem with 1st gen titans.

blower for heater came on weak and eventually stopped . Hit a cold spell of 10 degrees and of course that is when it stopped working . Checking fuses and for wiring issues first .
