Good evening, I have a 2015 GMC Sierra 1500 4WD. This evening while heading home I noticed my temperature gauge was malfunctioning as it did not register a temperature after about 5 minutes after start-up. Also, upon arriving at my final destination, the temperature gauge still did not register a temperature and the cooling fan kept running. Any ideas what could be causing this problem? Thank you.
