Check that you have the selector set to blow out the vents and not the defroster or the vents by the footwells. Does it sound loud like it should be blowing strong or is it weak? The selector 'doors' under the dash work off of engine vacuum lines. If they won't 'select' when you change the knobs, there may be a vacuum line leaking. Also, make sure the blower motor is not all clogged up with leaves and debris.

You probably have a vacuum leak on the passenger side. its a small plastic hose some times they come unpluged from the engine. or brake.

SOURCE: AC not blowing cold air

Most likely the A/C system needs to be recharged with freon.
Most shops charge under $50 for this service.

SOURCE: Cold AC but weak Airflow---Also Driver side not as cold as passenger

The air doors are controlled by actuators that on of them or so may need replacing.

SOURCE: AC STOPPED BLOWING COLD; ONLY BLOWS ON MAX MANUAL SETTING

Your AC is low on refrigerant; The AC compressor needs a minimum amount of regrigerant to run. If and when it does run (while low on refrigerant) the air coming out of the vents will not be cold. The refrigerant you require is R-134A and is available over the counter but if you are the least bit unsure as to how to add refrigerant, taking it to a garage that does AC recharging would be your best play. If you want to try to add refrigerant on your own you will need the following, 1LB can of R-134A, an AC hose adapter to deliver the refrigerant, and preferably an AC pressure guage to ensure you are not overfilling the AC line which will damage the system.
