Air does not get hot replaced thermostat already,coolant level is good
If all was done correctly and your sierra is running fine it has to be your HVAC system blend doors not opening correctly...It is common for a lot of vehicles but mostly Dodge has this problem...These doors are inside the unit and they will break and not allow anything through or else stick open and allow everything through and not allow a change in air /heat blend...The quickest cheapest way to find out is to take it to a chevy dealer and describe your problem and only ask for a diagnosis...They will tell you if the actuator isnt opening the blend door or if the door is broken...It can only be done with a Tech II GM scanner..but ot is worth the money ...They make a quick fix which requires cutting the body of the unit and replacing the door or else replacing the faulty actuator..........This is true I hope this helps ...........Metalpoet
