AC COOLS THEN GOES TO WARM

2004 Chevrolet Suburban • 70,000 miles

On a 2004 Chevrolet suburban the ac cools then goes to warm and back to cool while driving. Could you please give an idea what could be happening please? The air cools then goes warm and back to cool while driving. It's continuous while driving. Thanks

You could simply have a low charge of R-134a refrigerant. A reputable repair shop will attach a set of pressure gauges to check the state of charge.
