It's getting hotter and more of a nuisance now. I have a 1999 Chevy Lumina 4 door Car that I just recently purchased. I have to keep it on a certain setting (the one with the man sitting and the air hits both his face and his feet-whatever that one means!), and the air only comes out of the vents when I have my foot on the brake or not hitting the gas at all.
This really sucks.
However, when I have my foot on the brake, it works beautifully - as beautifully as it can on the ONE setting.
Can anybody tell me what the problem is and how I can possibly fix it? Keep in mind I am not a wealthy person-so "buying a new car" won't work!

Broken vacuum line. Look on the drivers side and you'll find a 1/8" plastic vacuum line, it goes from engine down under the battery and to a canister under the front of the finder. mine has broken twice, it can be replaced with 1/8" copper line, never to break again. To get to the canister remove the screws from the inside finder well, just the front part. The canister is held in place with two screws. The line plugs on to the canister with a rubber boot, goes up under the battery and the inside finder then to a L shaped rubber boot at the engine. 4 feet of new line is plenty. For your info, this is one of the best cars on the market and has a very hight rating in crash test. I guess they stopped making them because they last if taken care of. I've had mine 10 years and will have it untill the wheels fall off.

Few years back I saw an inventor that created a gadget that turns off the A/C during hard acceleration. Supposedly that would save some gas. It isn't really difficult to figure out how this device works.
It sounds like that either (a) you have some loose connection or (b) some body created his own home grown A/C disconnector - except screwed it up.
The only advice (from your description) is that you should check for any obvious bad wiring. If that is not it, check to see if there are any foreign devices under the hood or under the dash that might be badly disconnecting the A/C blower motor.

You have a vacuum leak. Most likely in the vacuum servo that controls the vent position. When you accelerate, the engine vacuum drops to zero, and thus any vacuum leaks in the dash will cause the air to go to defrost. Put it on the vent only position and listen carefully for a hissing noise, you may be able to find the problem yourself. Getting it fixed may be another story, depending on where the servo is located. Good luck!

You have a vacuum leak. The vent controls have a vacuum powered actuator, and you get the best vacuum at idle. When you hit the gas, the vacuum goes down, and the vent actuator stops working right. The leak could be any of the vacuum hoses under the hood, but is probably a bad vent controller.

Sounds like you have a vacuum leak in your damper system, or one of the damper motors is not funtioning properly.
When you hit the gas do you hear any strange hissing noise? or is it not quiet enough to tell.
This can be frustrating when trying to pin point the exact location, so you may need someone to lay under the dash on the passenger side to locate the leak. Chances are one of the vacuum motors is the cause.

Cars are made so that when you push the gas pedal your engine takes over and asserocies like your ac take a back seat to your engine.
