Want this question answered?
Vents should be situated near windows. Windows that are north or west facing should get a vent before a south or east facing window would get one. (Assuming that the vents also supply heat.)
should be on floor.
replace? why not fix it?
Ceiling. Cold air fails
Return air vents.........
55 degrees to 60 degrees
There should be at least a 12 degree split between the incomming air and the air comming out of the vents.
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
I have a 01 Buick and the ac temp that comes out of the vents is around 50 deg - at idle and around 45 deg at highway speed - Is this normal a normal temp? or should the ac temps be colder?
normally 15to 20 degree split between return air and discharge..
My ac blows only in the defroster and not any of the other vents i have 98 ford windstar 3.8 v6
