  1. I had a 16 duramax Colorado and loved it. I traded it for an 18 duramax Colorado zr2. The only problems I had were ac related and the notorious Chevy lean lol. Nothing engine related. Sent from my SM-G950U using Tapatalk
  2. I had the same thing happen, first they said it was normal. I had to call gm and log a complaint. They kept the truck a whole week and had it idling trying to replicate for gm techs. They finally asked me to come in and get it to blow hot. I replicated it within 8 minutes. They had the truck connected to the computer while I replicated the issue. They concluded it was the compressor and expansion valve. Replaced both and been working great since.
