Hello! There is a Technical Service Bulletin TSB # NTB07-017 which calls for the replacement of the Heating and Cooling unit...I would suggest having the dealer inspect the unit when you bring their attention to this Bulletin #...There are several reasons that you do not have heat...Blocked heater core...Defective door controls...Or simply a bad thermostat...When the engine reaches operating temperature is the upper radiator hose hot an hard?...With the heat control turned to high are both heater hoses hot?...This would eliminate the thermostat and a blocked core if the answer to both questions is yes...That leaves the heat/cooling control unit and a trip to the dealer with the TSB # is in order...Guru...saailer

Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.

No matter how much you don't think this happens but when your heater is on the a/c also goes because it act's like a dehumidifier so in the winter when you crank the heat it takes the moisture out of the air to make things heat up faster, There will be a relay switch on the other side of the fire wall inside the cab that will either have a seperate fuse that you will need to change or you just have no connection to your switches on your dash. either way the best way to check it would be to take a volt/amp meter and check all your connections in your fuse box.

Changed the radiator fluid on 05 Armada, now heater blows but no hot air will come out even after 15 mins idle.


You have air in the system. You need to bleed out the air for the water to circulate. Find the highest point on your cooling system and open it to release the trapped air. Crack open a heater hose this usually will do the trick. Once coolant comes out then tighten up all conncetions.
Good luck and thanks for your question and I hope my suggestions help. Don't forget to rate me.

A/C NOT BLOWING THROUGH FRONT VENTS...2004 ARMADA


The distribution of the air in your car is controlled by little vacuum powered doors in the vent system (inside the dash). You either have a vacuum hose that is disconnected or one of the air valves that runs the door is bad. With the engine running, put your head down under the dash and see if you can hear a hissing noise. If you can, it is a loose hose and just need to be reconnected-not an easy task as there is not much room to work.

Heater Troubles


possibly/most likely, a restriction of some type to core or in core, more than likely corrosion internally. Cheapest & best thing to try is complete cooling system flush, & reverse flush, to move that out of there if it will come. If that fails, I would circulate C.L.R. through heater core to help remove any calcium etc deposits.

Heater system not putting out hot air


with the engine idling you water temp might not get hot enough to open your thermostat that lets hot water go through your heater core. I would first have the easiest thing changed. the thermostat could be you main problem.I hope this helps you.
