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.
