It has 37k miles. AC works for the first 7 minutes and stops blowing cold air. I was able to gather the fault codes and plugged it in and it indicates I have a bad temp sensor. But before I buy this new temp sensor, I was observing that #7 code started to get smaller; it started at 17...then to 9 as I was losing cold air. Is that an indication I have a freon leak or is it the diagnostics giving a false positive on the freon level. It is just weird that the freon level can fluctuate that much.
