I have had this car since 98 and the air conditioning is what has gone out. I have replaced a compressor in 1999 and in 2006 I had to replace everything on both sides of the air (the drivers side and passengers side). The car has been used strictly for highway miles (200 daily) until two years ago. Oil changed every 3000 miles. Engine runs smoothly and has no problems with it.

    Sounds like you may be leaking freon through orifice valve. they have little doughnut like rubber gaskets that go bad. Buy some of the system dye, put in system, I think through low side and then check for leaks with black light, dye will glow.
