 All right, we are back. Drive Radio, KLZ 560. Thanks for listening to us. Jerry is next. Jerry, are you back now? Hello, Jerry. Can you hear me okay? There we go. I can hear you. Go ahead. Okay. So a 2007 Silverado, my AC blows real cold for about seven, eight minutes, and then it starts getting a little warmer. Is that normally low refrigerant or some other problem?
