Question about 2003 Ford Windstar

1 Answer

Vacume leaks The AC controls inside the car go from the floor outlets to the defrost position when you put a load on the car during acceleration. The manifold for the up and down motion has been changed. The engine manifold, all three parts has been changed, but no luck. The ac still will not blow out the vents except at slow speeds and the engine is running rough.

    I just bought this van used and it is doing exactly the same thing. The engine runs fine, but when stepping on the accelerator to enter traffic, climb hills, etc. the fan switches to blow out the defrost vents until the engine returns to a normal running condition.

    Please help, as this really annoys me!!!

I have heat but no dash defrost or floor heat

it could be a bad switch... it could also be leaking vacum lines (vacum is what operates the dirictional doors). it could be a stuck door, or bad hinge. it could also be loose ducts underneath the dash.

1985 chevy idles high when defrost is on

Interesting. If it is a vac leak you should be able to plug the line from the intake to kill the leak.
My guess would be the idle speed control is raising the base idle to cover the load the ac compressor would put on the engine.
If the compressor is not working, the computer would not know.

When AC is on it blows out the vents until I put my foot on the gas. While Im pressing the gas it comes out the defrost vents then take foot off and it comes out regular vents! Any ideas??

When the gas petal is pushed down the engine needs a amount of vacum to run.If there is not enough vacum it will pull vacum off heater/ac box inside which controls where the ai flow is controled.Check intake for vaccum leaks,hoses,connections.look for vaccum lost.

Ac vacuum

There could be a vac tank problem or a vac leak.
Most american vehicles use a plastic ball or object as a vac holding tank. The tank or a vac hose can be leaking.
If the system fails, the default position is the defrosters for safety.

1997 Ford F150 Air Management Problem. When Fan turned on it only blows to defrost no matter what I set it to AC, MAX AC, PANEL or FLOOR. Visually inspected vacuum line behind battery looks ok. What...

The air flow is controlled by vacum. I would start by inspecting all the hard plastic vacum lines under the hood. If you find none broken or loose , then inspect the control panel. by "default" the air is derected to the defrost position.

The air flow vent is stuck on defrost mode. when i switch to a/c or face/floor no air is directed out. the fan seems to be working fine

The air direction is vacum controlled. If you have 4X4 and ESOF ( switch in the cab) then you need to inspect the vacum lines that go to the hubs and possibly the hub seals. "default" position for air flow is the defrost position. If you DON'T have 4X4, and it's a diesel engine, inspect the vacum pump, If it's a gas engine then look at all the vacum lines from the intake manifold for a leak.

95 camaro 3.4 sucking air from a/c vents & loss of power cant find vacume leak

Not sure what you mean by loss of power. If you mean lack of acceleration or bogging down, than a bad cat convertor can cause this problem because you are lossing vacuum during acceleration causing the vents to switch from floor to defrost. Hope this helps leave comment.

The ac only blows out the top(defrost) and floor at the same time. it want blow out the front vents. Whats the problem and how to fix it?

The problem is that the control is vacum operated,so either the rotary vacum switch is bad or you have a vacum leak under the hood or under the dash area.

Air stops blowing through the vents when accelerating

u have a loss of vacuum to the ac mode control switch, this switch applies vacuum to diff vacuum motors to move air to diff outlets, dash, floor, defrost etc. either the vacuum line or vacuum resivior at the engine is leaking or the mode control is leaking vacuum.
