My A/c quit blowing cold in the 1999 Oldsmobile Silhouette I just purchased. Stopped and bought more freon with a sealant in it, worked perfect after we filled it. Next morning went out and again, it
Was blowing warm again and now there is green
freon all over under the hood.... What do i look for
so i can relpace it and have my a/c back and asap.
