Alter Hvac To Blow Vents&floor

[Nemethjames1]

I don't like how when running the heater or ac you can select the dash vents, floor vents, defrost, defrost floor vents Ect... It's been 110 here in northern Cali, and I was wondering if anyone has a trick to make the floor and dash vents both blow cold or hot, don't care if I loose the single use of one, really just want to have BOTH blowing. I'm going to look on alldata and see how the vacuum lines are set up and see if I can splice one into another or something. Such a dumb design . When it's freezing cold and in my other car it's great to have warmth on my feet, legs and face chest area! Or same goes while using ac with 110 degree weather

Anyone agree?

Hey there I don't have much idea about vents and don't know the trick to make the floor and dash vents both flow cold or hot air, but I have found a source look what I found which can help you out with your query.

It all has to do with vent door position. I am not sure if one can modify the controls to stop the door halfway unless you just put a physical stop inside the venting tubes. Search for an exploded vew of the ducting to determine the stopping point you can make work.
