I just recently bought a 7g (97) and. The previous owner said the ac just needed to b recharged so today I went to the part store and got sum freon and recharged it. But it only blows out hot air I checked to see if I had any leaks with soap n water to see if saw bubbles and nothing I let it run for a good 30 mins to see if any cold air came out and nothing any suggestions on wat I need to look for that could be the culpret????
