SOURCE: 2005 toyota tacoma air conditioning cold on left, warm on right

I would not suggest repairing yourself. Sounds like a blend door actuator. Not to sure on a toyota because i know more about domestic but i believe that the dash needs to be taken apart to replace this part or to atleast examine your duct work behind the dash. Hope this helps! ~Derek~

SOURCE: A/C blows from defrost and floor vents, nothing from dash vents.

the switch where you turn it to blowing at your head is probably out. you will need to replace the switch control where your defrost, foot, head etc. what make, model, year is your vehicle?

SOURCE: Passenger ac vent cools and driver side ac vent do not

It sounds like a heater blend door issue inside the heater box that is actually not closing all the way to allow either cool or hot air or visa/versa.

If you want to do a good job you are going to have to pull the dash. Once it's out you will see every thing.

I cannot get air to flow out of the center vents in my 2005 ford focus zx4

Duct Vent Motor under dash (Cabin Air Flow Vent)
not defrost,floor,recirculate or blend door,ones
Hope you can reach it
If you go to Motorcraft Web Site you can see a diagram
of the vent motor or actuator & order on Amazon,BUT
you have to first diagnose that is the issue & get the right
motor if it is.
I use a professional scan tool to check for codes on the
electric ones & then look under the dash to see if they move
as they should
Near impossible to get your hands up there to replace

My ac unit is working but will not blow air out of the dash vents. The blower is working

Hey man if the blower is working and air is coming from your other vents i have a few ideas.First i would start by checking your vent selection switch something may be stuck where the dash vents open. If the selector is fine you should try checking the ducting behind the dash it could have come apart or simply be cloged where it routes air to your dash. hope that is helpfull.

Ford diesel excusion A/C won't cool

Any performance testing re auto A/C requires consistant engine revs highway revs eg 1800 exit ramp eg idle stop start 800revs leading to much reduced A/C compressor speed and therefore performance output .Also all testing its desirable to close the bonnet to control design air flow through the engine bay .Also check under dash passenger side air flow pos a filter on return air duct or something sucked up into paper etc .good luck!

Air conditioning blows cold through the defroster vent.It quit blowing through the dash vents completely.

Your control valve for your duct work is having a small problem, its just not opening. The duck system work lid the heat/ac ducts at your home. The only difference is you can control through a vacuum controlled valve where you want the air to flow. What has happened, is the valve has shut the system at the neck( where duct is connected for all the vents) There are three areas that could be wrong. 1- a vacuum line has come apart or broke( they are just made of rubber). The line would have to be replaced. 2- the controlling valve is stuck, and either needs to be unjammed or replaced. 3- your control unit(mounted on the dash, the one you use to adjust everything) has gone out. Being you have an older car(great year for caprice)you also have some cables on the control unit. One of these may have gave way(broke) or the plastic clips that hold them may have snapped. You can manually ope the vents from under the dash. It will be under the center toward the passenger side. You will see the ducts leading back to your control box. you can also see the rads and control lines there. just adjust the arm til you get air in the vents. its a tight fit, smaller hand work great for that. I hope this helps you

1998 Buick LeSabre Custom I will turn on the A/C and air will only blow out the defrost vents sometimes it will change over to the proper vents. At times I use to switch it over to heater and back to A/C...

Hi! It may not be a vaccum problem. I think that the hoses that goes thru the main vent is the problem. They may have fall thats why theres no air coming out of the main vents only on the defrosters. Check the hoses and connect them to the main vents and it will resolve this. HOpe this helps and have a good one!
