SOURCE: How do you change a blend door actuator on a 2003

Not sure why previous poster showed you how to fix a switch in the door, but anyways.....
I had same problem as you.

My Yukon has the single overhead door, not the "barn-doors", hopefully yours is the same. Open rear cargo door. Using a trim tool (buy the set from Harbor Frieght for less than $10) remove the lower trim (at carpet), upper trim (at headliner), then the right pillar trim (mine has small Bose speaker in it). Loosen trim between passenger side back door and the cargo area main right rear trim. Remove main cargo area right main panel, by unscrewing the big black know, prying out the small plastic plug, and carefully disconnecting the AUX power plug (looks like a cig lighter outlet) once you can get behind the panel a little bit.

Now you are looking at the entire rear system. There are 2 of these actuators. The front one controls airflow going either to floor or ceiling vents, the rear one (towards middle of entire unit) controls AC vs heat percentage flowing through the ducts. Unplug the connector, and 3 screws to remove it.

Install is the reverse.

Behind the glove box only two screws. You will have to move the vacuum and it is right there.

No they do go but not by changing the battery its just whats known in the trade as the dominio effect ,us mechanics are used to it this is where you change one thing and something else down the line goes wrong and the poor old mechanic gets the blame ,I think its just coincidence that the actuator valve has decided to go at the same time as changing the battery ,Dominio effect no doubt you will change the valve and then you will get two punctures at the same time .

1995 GMC pickup. Cold AC will blow through all settings (defrost, front vents and flloor) but warm air will not come out the defrost. You can hear something click in the dash that you assume is some kind...


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

2000 yukon denail front a/c not cold rear a/c is


First of all get the Freon level checked, if Freon/ refrigerant is low then it can cause this problem.Wen Freon is low it takes time to cool.--- So first get Ac pressure tested.It can be tested at any local car garage.Some times pressure will be checked OK, but still if Freon is getting clogged in the line/ tube then it will not reach the front , but reaches rear then front will not cool, but rear will.--------

But mostly this problem is related to blend door.

If the rear is working well and front is not I would suspect a blend door or actuator issue in the front.Double check and see if you can hear anything moving when you are adjusting temperature from hot to cold.Also check and make sure the air flow moves properly from defrost to vents and floor etc.

Either a bad blend door motor or Climate Control Assembly. The A/C heater function selector switch combines a vacuum selector valve for direct control of the vacuum control motors and electrical input to the instrument cluster module.

------------

The blend door actuator is located behind the glove box.-----

I have a 2000 GMC Sonoma. The heat gets warm until the fan is turned on then the air turns cold. Acts like it is not switching over from ac to heat. what can i do about it?


Probably the blend door not actuating. I do not have the manual on where your door actuator is. It's usually right of center under the dash. Look under there and see if you can see anything trying to move when you change the temperature setting. Also, if you hear a clicking noise, that would be the actuator stripping it's gears. If youy can find the actuator, take it off and see if you can manually rotate the door hinge. If yes, replace the actuator. If not, you will have to remove the heater box to find out why the door is jammed. The actuator looks like this:

A/c blows cold on passenger side, hot on drivers side


To correct this problem u will need to replace the air temperature control blend door and the electric blend door actuator inside the dash, contact your local dealer for parts, they are dealer only parts
