89* isn't hot, according to heater controls

HD2500 · Sep 27, 2014

I have the dual climate controls in my 04, and for some reason it only blows hot air when it's set to 90 degrees. if I lower it to 89, no more heat...passenger and driver side are the same. with winter coming, sure would be nice to find that happy medium between cooking and freezing...lol
Any thoughts?

could be that its the 6.0 ill trade you my 5.3 for the 6.0 i dont mind if i dont have heat. >.>

Could be your controls are toast, or your thermostat is stuck open till you turn it to max

sounds like bad controls

found the issue! there's a cabin temp sensor that can go bad apparently...it's located above the driver's head, looks like a little speaker.
$25 for an ACdelco replacement on Amazon, good as new!

Nice!! Good to know! My dad and my brothers trucks both have that same set up so if they have issues well know where to look

Bonecollector · Oct 6, 2014

The mic for Onstar is in the side of the overhead console I believe

on a opposite note, the lumbar support in my drivers seat doesnt work, and its a manula crank, its kinda dissapointing

well for like phone controls because mine had it in, and i knew when the black box is that clips on the overhead. i just wish i knew what thread size the roof antenna is so i can put a stubby one on
