Temp gauge

[Tockytop75]

Hey guys I have a 2014 Silverado and recently the fan has been stuck on to where I have to un hook battery to get it turned off, and when this happens the temp gauge does not work. Any  ideas?

Could be a faulty coolant temp sensor.

I'm having the same problem with my 2015. The fan turns off after about 3 minutes of the truck being turned off. It only does it when I use the heater.

Yep, a friend at work, with 2014, just had to get his coolant temp sensor changed out yesterday.
Same thing, fan stayed on and no reading on the dash.

I started with swapping the thermostat in my 2014 because of the same issue. Didn't solve the issue, so after swapping the temp sensor...presto. Problem solved

I changed the cooling sensor. Everything is working great now
