2001 Ford Taurus • 151,000 miles

I have a 2001 ford taurus se when I turn my ac on sometimes it only blows hot air when it does blow cold air it will only be cold for about 10-15 minutes I have tried getting a new relay and I have tried putting more refigerant in it but neither have worked any ideas?

To properly diagnose this ac problem, you will need to have someone quilified/trained in auto ac, hook gauges to the system to monitor pressures to find out what is going on, adding r-134a to the system without knowledge of whats going on can be dangerous, better off having a trained tech look at it.
