Nissan Sentra Air Conditioning Problems

[ryanwg24]

Hey everyone

I have a 1992 Nissan Sentra that is having issues with the air conditioning not blowing cold air. When I went to check the fuse, it was blown so I put a new one in. I drove it around for a bit and even with the new fuse, there was still no cold air coming out. Went i went to look at the new fuse, it was blown. Before I had this car, the previous owner also tried to fix the problems with the ac. He recharged it and it started working again, but a week later the cold air was gone. Any suggestions with this problem would be greatly appreciated.
