      I have a 2015 Yukon XL Denali. The temp gauge drops to 160 and the fan comes on intermittently. We have changed the thermostat, wire harness, removed/replaced the battery cable, reset the fan codes ….. everything we can think of about 18 times and I’m still having the same issue. Next up is possibly replacing the ECM? Anyone have this issue and had a permanent fix?
