2005 Ford Focus Air conditioner problem

It sounds like the vent door actuator isn't working. I believe your vehicle has a vacuum actuated door. Check to see if there are any vacuum leaks. If you lucky, with the engine running, you may hear a slight hissing sound from under the dash.

That's a tough one because it will be based on how long it takes to find exactly what is causing the issue. I have to ask you another question. When you turn the AC on, have you checked to see if the AC compressor is turning on?

By the way. I envy you. I'm in PA and sick of cold weather. Finally, it's starting to get nice and what happens. Rain, rain, and more rain.

You can ask as many questions as you want. Honestly, I don't mind. The compressor is located under the hood. It is a belt driven accessory. It will turn all the time, but when you turn the AC on, there is a clutch that will engage and turn the inside pulley on the compressor. You will hear it click when it engages.

Have a helper open the hood, start the engine, and then you watch the compressor as well as listen for a clicking sound when the helper turn the AC on and off.

Let me know what you find.

That could be the result of low Freon or a bad cycle switch. I would check Freon first.
