Sorry for the delay Dan on my reply...
I had a local AC technician check it.. I also asked them to check if there is any leaks they said they did not find any leaks and the system is full of freon. But when they reset the computer for the AC the AC start to blow cold air again.. Unfortunately after 7 days the AC stops on giving cold air again., since it works when you reset it. How do you reset the computer for the AC? and I also want to check the relays how do you check if its still a good relay?
