SOURCE: 2000 GMC Sierra 5.3 Litre, won't blow hot air

I experienced the same head ache. First attempt was to replace the thrmostat and after taking it apart I realized that there was nothing wrong with it. I then removed the plastic cover/panel located under the dash board on the passenger's side. (only a few 4-5 smalls screws) Removal will enable you to see the on/off switch/gate moving/rotating as you turn the knob to hot or cold positions, on the control panel. If that switch/gate seems to work ok, then the trouble is within the heater core. Many mechanincs suggested that I replace the heater core. A very expensive proposition.
I checked the heater core supply/intake hose and found it hot to the touch, while the return hose was nearly cold. It was definitely a heater core blockage. I removed both ends (supply and return) hose connections/clamps. They are located near the fire wall in the engine compartment. A special tool is very helpful to remove those clamps easily and to replace them as well. It can be done the old fashion way but this tool was a life saver and reduced work time to just minutes. (Tool is $70.00 bucks at auto parts store,so I borrowed mine from a mechanic/friend)
I then hooked up a garden hose to the return end of the heater core and reversed the flow of coolant/water through the heater core. My truck is a Sierra 2000 and I refuse to see how a heater core could get clogged up with clear coolant alone. To my surprise a flat piece of rubber about the size of a quarter blew out of it and the flow of water became unobstructed. I reconected the ends of the hoses to the heater core, replaced the lost antifreeze & everything returned back to normal. No money spent for something most mechanics suggested I replace control valves/switches ($280.00) replace heater core ($500.00) etc etc. I am glad I was curageous enough to tackle this myself and save a few pennies. Good luck, and I hope this will work for you.

Probably the left temp actuator. The wires in the right I/P junction block could have poor tension also, but it's usually the temp actuator.

Sounds like the front side tempeture door actuator is faulty.
You can take it to a good repair shop and have the HVAC controller scanned for codes. It may help in diagnosis, but I would suspect the actuator.

Hope that helps.........

good work, the clicking noise you hear is the blend door trying to move. this door is what controls the temp. the most common reason is the actuator motor is bad but sometimes the door hinge breaks, this hinge slides into actuator and is used to move the door. you will need to locate it on the heater box by locating the noise and then remove the actuator and see if the hinge is broken, i will try to enclose some picture to help you. good day, hope this helps.johnjohn2_142.jpgjohnjohn2_160.gif

The electronic control ac works normal on


The temperature control doors are controlled with electric actuators. Often what happens is either the drivers or passenger side temp door actuator will work properly for a while then suddenly move the door all the way to hot or cold [usually hot]. If you shut off the vehicle, wait a bit and restart it, if often will work fine for a time but then act up again after a while. I've replaced quite a few actuators for just this problem. They are located behind the dash on the HVAC unit and are fairly difficult to get to. I don't know if these actuators are available at parts stores yet but I get all of mine from the local GM dealer.

How can I determine if my compressor is out on my


If you still get cold air out of the rear vents but the front only blows hot air you may have a bad temp door actuator in the dash, it may be stuck on hot and not able to move to cold air. However if you are low on freon with a truck that has front and rear ac then there will be a temp diff between the two. If it is hot air out the front like the heat is on then you have that actuator problem but if it is cool air about the same as the outside air temp then you may be low on freon.

2004 GMC Yukon blows hot air out of the driver side vents when the AC is on. Cold air come out of the passenger side.

2002 gmc sierra blows Hot air thru ac vent on drivers side. Whats going on? Setings are set for cold air and we are getting cold air thru vents on passenger side.


We have this fairly often on our gm fleet with dual air controls. Replace the actuator and you will be good again (for a while!)

the door opening & closing on Max a/c is the inside/outside air intake door.
The temp blend door is the one you are concernd about. It says you have to remove instrument panel for access. ouch!!!

-------------------------------------
A/C Electronic Door Actuator Motor
The A/C electronic door actuator motor (19E616) is located on top of the A/C evaporator core housing assembly.
  • Its function is to move the A/C air temperature control door on command from the control assembly.
  • The A/C electronic door actuator motor contains a reversible electric motor and a potentiometer. The potentiometer wiper is connected to the actuator output shaft and moves with the output shaft to indicate the position of the A/C air temperature control door.
  • Battery voltage is applied to the ends of the potentiometer. The voltage available at the wiper indicates the position of the potentiometer. The actuator wiper voltage is sent to the control module and matched with the wiper voltage of the module potentiometer. The printed circuit board then drives the actuator motor in the direction necessary to make the actuator wiper voltage agree with the control module wiper voltage.
