Can I get a colored diagram of the vacuum hose for the ac? And a picture of the door for the vents inside the car so I can see if they are open? Ac is only blowing on the floor and the defrost but on both the ac is very cold but I need the front vents to work so I can feel the air hit me. THANKS

Thanks but one last question on the diagram the number 3 hose, if I change that that goes for the ac that's going through the vents in the car right?

Not through the vents. It comes through the firewall to the block.

Okay so Is that the hose I should be changing if my ac is only blowing through the defrost and floor vents? I have an understanding I just don't know which hose to change out, cause I know there's a leak. Thanks for the help

So basically for the ac to ONLY be blowing on the floor and defrost vents would mean that, that engine vacuum hose has a leak or so?

No, there are electric mode motors controlled by the car hvac system as well. You can try the hose and hopefully it works but if it does not, then there are other issues.
