i haven't posted on here for a long time now but i still have the 04 max.

my problem that i am facing right now is that the heater does not kick in.
the displays on the screen still show the standard functions and what not but it just wont blow any air.

can anyone help me out?

 

Are you saying that it does not blow air at all, or just does not blow hot air?

Things to check if no hot air: Coolant level, hoses for leaks. Do you hear any odd noises in the heat/ac system?

 

Need more details...

If it dosen't blow at all, check fuses, blower motor, switch assembly.

If it only blows on high it's the blower motor resistor.





You need heat in WA?

 

I'm sure he does, I think Washington is the NY of the west coast, mild climates but it sure does get cold....

 

Check fuse 10 or 11, or resistor.

Service manual at http://www.vq35de.com/ESM/Nissan/
Section ATC page 43: A/C self diagnostic procedure. This should pinpoint if a sensor is bad, blower, etc. Look for "fan control amp" for the resistor controlling the fan speed.

Check fuse 10 & 11 (15 amps), then fuse 6, 10,12, 19 (10 amps).
