2003 lincoln town car A.C. problems

i also bought a 2003 lincoln town car with ac problems and only have had it 4 to 5 days and the guy told me it just had to run for a while lol should i keep it? i have not given one cent on it yet i was just going to pay down a $1,000 down but said to my self i better wait could some one please help? i bought it (as is) and the guy told me he would have the A.C. looked at but i guess he didnt,

Get rid of it. The guy didnt keep his end so return it before he forgets he even sold it to ya.
