Both cooling core fans running at start up and throughout run/drive time. Temp guage shows no temp reading. Replaced temp sensor on engine. Problem is intermittent, not full-time issue. Dealership cannot diagnose problem when it isn't occurring. Frustrating!
Same issue. Fans will run till I shut the engine and then shut off 4-5 minutes after. About every 5 weeks I have to disconnect the battery to stop the fans from running
My 2016 silverado did the same thing, temp gage reads lower than normal and the fans continue to run even after turn off the engine... Replace thermostat and Coolant sensor. Fixed the problem.
