I have a 1999 GMC Sierrra 1500, my air conditioner blows cold air for about 5 minutes then its just vent air. If I turn if I turn it off for about 5 minutes and turn it back on, it blows cold again, but for only about 5 minutes. It has been doing this for about 2 years. I have had freone put in, so that is not the issue, Please help. Thank You
