2012 Sierra SLE, 5.3. I'm having 2 issues and honestly am not sure if they're related. First the cooling fans seem to run full blast for no apparent reason. The truck can sit all day while at work and when I crank it, they're running full blast. It will also do it while chugging down the road. Temp gauge sits around 210 constantly so no issues there. Second issue is the AC. It seems to stop blowing cold intermittently, for a few seconds to maybe a minute. I am not sure if the 2 are related. I just purchased a new high pressure switch to see if that helps. System is charged correctly. Any ideas? No check engine light is on, I have not had a scan run to see if any codes are present.
