2004 silverado ac module question

2004 silverado ac module question

Postby gentlejax [OP] » Mar 26 2020, 2:12am

I have found that 2 of my modules were bad so I ordered all 3 for my 2004 silverado dual manual climate control.

I replaced the one in center by tranny hump. seems to be ok.

The one too the left of that one is giving me issues. I took off the old one and the sliding door thing fell off so I had to put it back on. I noticed there is a small section of teeth and when you install the door there is another gear at the top.

when I started the truck I watched the door move and I think it moved way too far as now the teeth are nowhere near the white gear at the top of the door. hard to explain.

how should the door be set when replacing this module? how should the module be set? mark on left, mark dead center or the right hash mark (on the module itself)

all the videos I have watched just say to move the shaft to fit into the module . I want to make sure I set it in the right position tomorrow when I go at it again. ran out of daylight. removed it 5 times for various reasons.

yes I also unhooked the battery and the fuse and let it do its thing but still its not right plus that door doesnt move at all no matter what the settings.

They are called actuators. The one you are messing with above the gas pedal is the mode door actuator. The others are blend door actuators.

I cant recall how I lined mine up. I took some pictures I think to make sure it went back close before I removed the old one. But I recall having to pull it off to correct the defrost door lever and tweak how the cam and door gear teeth aligned. Seemed like I watched how it moved and was able to set it in there accordingly.

still no luck. I removed it . set it too 12 oclock. soon as I turn the key it switches from wherever it is to defroster then something and then ends up at defrost.

I manually closed the flap and disconnected the actuator for the moment. I must have taken it off a dozen times and moved the flap to various positions as well as un-hooked the battery.

the air has always been stuck on defrost since i bought the truck a month and 1/2 ago.

Hmmm...not sure what would have it defaulting to defrost. Typically if the actuator is bad it will fail all the way to one side. But if you have replaced it...must be something else. Perhaps an issue with the hvac controls.

If it were me, I would be tempted to try a new hvac control module. But that is sort of just throwing parts at it. No telling if that will work. Could even be something going wrong within the BCM causing some issue.

actually I can pick up a better control module (the digital) instead of the slide style I have now. if it works great, if not still upgrade.

That is not going to work. They used different plugs for the different model hvac modules.
