Air conditioner smell

It may have leaked out all its Freon gas. If it uses Freon it will not be able to be re-gassed as Freon puts a hole in the ozone layer of the atmosphere. It is expensive to get an air-conditioner re gassed if it uses ozone destroying gas as the new gas is different and the air conditioner needs to be modified to run the newer gas if the Corolla is a older model. Could be compressor has gone faulty. but to replace it will mean it will have to be re-gassed.

The smell is probably related to the catalic converter when a cat goes bad it creates a smell similar to rotten eggs. You might need to replace the catalic converter. This will improve gas mileage and performance. The hot air blowing from the AC is probably a low charge on the Freon.

Antifreeze is only for the radiator, does not affect the air conditioner, make sure you have the setting on cold, if it is still hot than take it to your local air conditioner re gas station, most auto electricians do it, dealerships usually send them out which you end up paying extra for!!! You just need a re gas in your air conditioner.

You need to check your freon level. Go to your auto parts store and pick up a can of freon with a gauge and follow the directions on the can.

Yea it does but not anything like gas

first thing to check is loss of gas pressure due to leaks , this is the most common failure.

if gas is good then could be a number if things , compressor , climate controller unit , bad wiring or connections somewhere.

Check the A.C>Relay or It could be low or leaking freon

Check your freon lines make sure their not cut or damaged, check your fuses under the dash and in the engine compartment, make sure your surpentine belt is tight, also you can make sure your electrical connection is still attached to the ac compressor. Freon kinda smells like sewer gas.
