Sometime in last month I used my AC and it worked fine. About a month later I hit the A/C button and it blows warm air. I noticed my AC fuse in the panel by the battery under the hood was blown. I replaced it, hit the A/C button and waited to see what happened. Hot air again and a hot electrical smell began, and then my fuse popped. I checked my Condenser Fan and it was seized up tight. I ordered a used fan from Roverland and installed it today. I replaced my fuse and hit the AC button.....still hot air? Fan works fine. What can explain the AC working one day and not a few later? It was not a gradual event. Any thoughts?
