i had my ac on and during the day like afternoon, the air blows cold on setting 2 and 1 but when i turn to 3 and 4 it doesnt blow as cold, also on 4 my ac light sometimes comes on if i wiggle the switch but stills doesnt blow as cold, but at night 3 blows just as cold as 2 and 1 but 4 still doesnt cblow as cold , the other day me and my girl were sitting in my car and she felt sumthing kinda cold dripping on her leg from under the dash/ glovebox, on the passenger side, the next day i went to turn it on and the ac light wouldnt come on, the reason i am asking is my dad is a mechanic and if were to take it to someone else to have it checked hed get pissed even if he didnt have the time, so thats why im asking all of you if you know anything, also i had this wierd bussing sound that wouold click on and off when my ac worked any theories as to what this problem with my ac might be and if and if you would know how much a new ac system would roughly be thanks
