Hi,
I have a 2015 Sierra truck with ~130k. Today, two things happened. 1) The temp gauge stopped working 2) The engine fans come on after I shut the engine off and remain on for 3-4 minutes. It's only 50 degrees outside. I've never heard these fans come on in the heat of the summer.
I assume these two things are somehow related, being they both started occurring at the same time.
The heater works as it always has. It puts out heat...but not as much as other vehicles I have owned.
Any ideas what is going on?
Thanks.
