05 only blowing through main vent no defroster
I did a search and could only find problems with the older models so thought I could get something more model year specific. I am only getting air out of the main vents, nothing from the defrosters. Very little if any. It used to make a big woosh sound when switching from vent to defrost but I cant get it to change. From what I've read I may have a bad vacumn line, but where should I start looking. Could it be something else. Thanks for any help!

Most likely your mode door actuator has failed or is jammed.
The blend door is NOT the same as the mode door. The blend door blends cold and hot air together to the desired temp, so if your temperature control works your blend door actuator is working properly.

search for posts under my username. I've had issues with this about a month or so ago, lots of information to fix your problem. Basically 04 and newer trucks use an electric actuator to divert airflow, NOT vacuum.

1) Mode door
2) Blend Door
3) Recirc Door (I don't remember the technical name).

It would be covered if your still under the 3yr 30k mile bumper to bumper warranty.
I would do it yourself, I mean the part if I remember cost $30, and it should take you an hour to change out tops. (I could do it now in 15 min). You still have to "troubleshoot" the problem first because I can't tell you if it's the mode door actuator for sure. You would have to go and take out the old one, and move the levers around that it moves to see if they are free and not jammed up. If it's not jammed up it's most likely your actuator or HVAC control assembly, but most likely actuator. If your levers are jammed up then you have a bigger problem, which requires taking out the dashboard to the firewall(not fun).

I'm pretty sure yours is vacuum operated, doesn't use electrical actuators. Your system is different.

The mode door actuator is located under the driver side dash(it moves 2 levers under the actuator you can't see, and one it moves by a metal rod that you can see). You have to lie on your back with your head by the pedals looking up. There is a black plastic actuator with a medal rod hooked to it. THis is the mode door actuator. It is removed by 3-4 screws and comes out. It's easy to remove, just awkward position to get to. It is located towards the center of the truck, it's easiest to find by finding the metal rod because it's one of the only shiny metal things under the dash, everything else is plastic.
I did have to remove the whole dash because when I took of the mode door actuator, I found out that one of the levers it moves was jammed. I had to remove the dash to get to the air ducts to remove a piece of foam lodged in the system.
