Okay for the first time I started my truck and on the AC in said EXT 41. It has never done this before!!! I did note that it matched the outside temperature. But why would it start that two months after having the truck? Is this supposed to read or is the electrical messing up?

 

did you maybe hit the external temp button on the HVAC by accident?

 

Maby its telling you that its 41 outside and you dont need to run the AC.

 

I don't think I have one

 

I'm sure it was the outside temp but why show up out of no where? And now I'm getting a charger system trouble? Ugh wonder if they are tied in together?

 

How old is your battery? Have it tested. All sorts of things can go goofy when your battery starts to go
