I have a 2000 Mazda 626 and the AC does not blow cold air. I had it recharged and after a month it blows warm air. 2 mechanics have noticed that the freon is low after use, but after several dye test and pressure tests they can not locate a leak. Any suggestions??
You are in a cycle that is costly. You know there is a leak. It is somewhere and can be found. it could be in the evaporator coil that is not visible without removing some parts to get to. The leak is there waiting to be found. Good luck
it is possiable the leak is in the dash.if your leaking that much fron they should be able to detect it with a sniffer tool
