My heater is stuck on defrost and wont change from it .. all my fuses are good .. what would be wrong with it ? the floor is dry so i dont think the heater core is bad , and it pumps out great heat , i just wish i could get the heat to come out of the floor / vents / etc ..

 

i also have gotten another climate control thing and hooked it up , but the same results

 

You may want to look into a problem with the actuators, they're known to go out in GM vehicles, not sure what the deal is with them on 5th gens tho

 

ill deff look into that , thanks man
