So I think I have come into my first problem on my 08 Titan. Leaving work last night it was about 39 degrees out so I let my truck warm up like usual, once warmed up I started going to the gym and I turned the heat on, it blew nothing but cold air on like the ac was on. I checked everything it was on heat. I figured once I turn off the truck it will reset itself and work like normal. So after I am done at the gym it is about 31* out, after the truck warms up I try the heater again, same thing. I woke up this morning and it is still doing it. Any help or suggestions on how to fix this? Sorry about the long post.

Yeah it was working great that morning, then I went to get in it that night and it was just blowing cold air. I guess I will take it into the dealer in the morning, hopefully its nothing major. I tried turning the cold air on for a couple of minutes then the heat but that didnt work. Thanks for the suggestions and help.
took about 2 months lol. I had to bring it in 6 or 7 times to get it fixed. The first 2 times they kept telling me nothing was wrong, I got a thermometer that goes in the vent and it was blowing at 80 degrees right inside the vent. I tested my coworkers titan and his was blowing out at 140 degrees. I went back in and raised hell and they finally quit trying to tell me I was making stuff up. They changed a couple easy to get to parts and that didnt help. Once they finally figured out that it was the actuator in the dash they had the truck for 5 days I think, but that was because they had to order the part and just kept the truck while while they were waiting. The first few time I didnt get a loaner, once they figured out they had to take the whole dash out and keep it for a while I was given a loaner.Slight515 said:
Mine was the heater control unit is what they said, which I am guessing is basically the actuator. Of course they didnt have parts so I have another appointment on monday for them to get it fixed. Hopefully everything goes good so I can actually be warm in my brand new truck.

Experiencing the same problem with my truck , but can make heater work by not turning heater knob all the way to the full heat position . If I turn the heater knob all the way I can hear the air door moving until there is a load "pop" , then blows cold . Know there is a problem but hate the thought of leaving my truck @ the dealer for an extended stay .

I solved my heater problem!
Bought a new NISMO radiator cap.
So far, I get close to instant heat or within a minute of start up at 45-47 degrees outside.
If that didn't work, I was going to check the heater core, get a pressure test, and see if anything was blocking the flow of fluid.

1. If this is the case, check your fluid level to make sure that it's full.fpd7 said:
2. If you mess with the heater control and then later, it goes hot, it can be because of a faulty radiator cap...
So mine was fixed for a while now (while the weather was nice) now that it was cold today of course my heater stoped working again. All it does is blow cold air... Again. Taking it to the dealer in the morning, this is getting rediculous less than 5,500 miles on my 08 and ive been to the dealer close to 10 times trying to get my heater worked out and I also have a vibration sounds like a heat shield they cant figure out.

Hey, So what ever happened to get this heater, or lack there of, fixed? I currently have the same problem and the actautor has been replaced 3 times! The first time was under the 3/36 and then under the 1yr warranty for the part and the third time about a week ago the actuator again under the 1 yr for the second replacement and this time they also tell me the A/C control unit has an internal short and that that's what has caused the actuators to quit all 3 times and that I have to pay $460 parts and labor to replace! After raising hell that if that was the case it should have been covered from the get go, they relented and covered it. But now a week later, guess what? No heat! It seems like it starts blowing warm but then goes cool. What the ?? I'm reluctant to take it back since they pull the dash out every time and keep it for 3-5 days and I only got a loaner the first time. I don't think know what they're doing. I've seen alot of the other posts on this so I wonder if Nissan is aware of a fix and has put out a TSB. Other than the brakes this is the only real issue I've had but this is an '04 with only 24k miles so I guess it'll be the rear axle next from what I've read and heard. Thanks!! Rob
