Can't change what vents A/C and heat blow out of.


While it's possible there are other problems the repair procedure would be to replace the blend door motor and while doing so confirm that the blend door moves freely without binding up.

How to fix back seat passenger window on my car ?


The gear, that is attached to the actuator that moves that window up and down, may be stripped out or the actuator may be getting jammed at a certain point. The only way to really know for sure is to pull the inside door cover off and watch the actuator when you make the window go up and down. DO NOT PUT YOUR FINGERS NEAR THE ACTUATOR WHILE IT IS MOVING. Just take your time and you will be able to figure it out.

You have a mode door actuator bad or there is a problem in the control head. U can try to switch the mode door actuator with the temp door actuator to see if is just a actuator problem

Could be a vacuum actuator problem. or just a vacuum leak, period. I have a Jeep that when it has a vac leak, the climate system defaults to the defrost, no matter what you set it at.

I have a 2000 pontiac sunfire. I can hear the blower run and change speeds when I turn the nob, but barely any air comes out of the vents. I have removed the blower and checked that. The ducts are clean...


It sounds like vacuum is not getting to the vent, heat and A/C controls. Find the vacuum can. It may be under the hood on one of the inner fenders. The "one-way" check valve is usually located in the line and close to the can, make sure it works properly. The valve could be the very thing that's causing the problem. Trace the lines back to the vacuum block at the intake manifold or fire-wall, and also back to where the line goes thru the fire-wall. Check the can for leaks or obvious holes. They used to be just a plain metal can, but it could be a plastic ball. Check the lines as you go, for breaks and rub-thru's. Move the controls thru all settings and listen for vent door movement. Worst case is a bad vacuum motor or air flow position selector switch, and/or a faulty Blend Door Actuator. If you have been driving around with the Temperature knob or control set at the same spot for months, move it from fully cold to fully hot several times and wait for the air temperature to change each time. This will help reset the blend door and vacuum control system. Hope this helps... Let me know what you find.

Driver side air on the duel climate control is blowing hot and the rest of the vents are cold


Joey i had a similar problem in my 2000...The problem lies in the A/C Actuator. The Actuator is what opens and closes the vents, when the vents are open it allows hot air to flow through and when thier closed it prevents hot air coming in while air conditioner is running. depending on the year some vehicles require an upper and lower actuator. they are fairly simple to replace, and dont take much time. most actuators are located under the control switch box (radio, a/c dials) parts run about 60.00 each.

How to replace 2000 buick century temperature actuator


First, what is the problem that you need to replace the actuator? Is the air flow from the vents not changing? If this is the problem, the actuator is inside the venting behind the control panel and is difficult to get to but is possible. Follow the hoses on back of temp controls to the actuator. There should be 2 small bolt screws to remove to change out actuator.
If this is for something else, let me know

Heater only blow out the vents


There are servos that move air control gates, some were controlled electrically, and some were vacuum. It sounds like there's a vacuum line off the vacuum reservoir under the hood, or a vacuum line has came off one of the servo diaphragms.
