The air vents are control by vacuum line and or linkage.

Listen for hiss or feel for vacuum leak under the dash,

Feel for broken linkage(s) that are close to the vents.


WORK BACKWARD if you have small hands to feel out where is the missing link.

2003 ford zx2 air conditioning not blowing cold air


Check and see if there is any Ice on the copper line that runs from condenser (outside unit) to air handler (inside) if so you need a charge. You can also make sure the fan is working on the condenser unit outside it should spin when you have the air on. If it is not you have a bad fan motor. there are other things it could be but these you can see.

Hot air comes out of defrost vent at top dash and cold air out of


Hey, what setting is your A/C on Max AC? AC? Cycling air in vehicle or taking it from outside

The car icon on the right in this image is what I'm referring to when I say cycling air in vehicle.

Also, do you ever have cold air blowing? on any setting or any speed? if not, find your A/C fan, it is smaller the the engine cooling fan, sometimes there are 2 fans together. The AC fan should be located at the front of the vehicle and is usually electrically powered.

Also try to find your compressor, looks something like this:

is it running? is one pipe hot and one cold? (the pipes I am referring to are inlet and outlet pipes of the A/C compressor unit.)

Hope this helps, keep me posted
