I own a 2006 Chevy Aveo LT in the United States and as the warmer weather is coming I wanted to test and see if my A/C works and it dose not the cars heater works but when ever I turn the A/C on I her the compressor kick on and then as it cycles I hear a hissing noise coming from somewhere in the dash area what should I do live in a place where if I drive somewhere I will be there in 5 minutes but for longer trips it would be nice to have working A/C any ideas?
