A/C!
Yes, that's right.. all I did was buy 3 cans of freon and walla.. a/c blows ICE COLD!
The original owner said the a/c was toasted..
(The interior blower was also "toasted")
All that turned out to be was a fuse.
So in all, literally the ONLY thing wrong with the car is the oil leak.
Best $600 I ever spent.
