hi there

Let me start telling you that I'm outside the US, in South America, so some things that are easy for you there are hell around here, no AutoZone or similar stores here, so trial and error part replacement is not idel since most parts have to be ordered online and the waiting times are not praactical to say the least.

My problem so far is that I have no heat, no matter if the AC is ON or not, vents, floor or windshield, all air is cold.

I've been reading and already checked the blend door by droping the glove box and I cannot see anything there honestly, looked for the actuator mentioned in several posts but cannot see a thing in there, probably because I have no idea what I'm looking for, I do see the white/clear box and another black box on top of it.

If that box needed to be replaced I can see 2 screws I can get to from the glove box, but what about the 3rd one is supposed to be behind it ?

Any help would be appreciated, if you need more info let me know and I'll do my best to answer quickly.

white box is the blend door motor. grab a flashlight, look under the white box, you'll see a shaft going into the box its attached to. turn truck on, vents on defrost. then start with temp dial on cold, and move it to hot. watch that shaft between the boxes, it turns but very slowly. if its not moving, you need a blend door motor, if it does turn, you need a blend door most likely.

the third screw is at the back, a 90* philips head is the only way, its time consuming but possible. i left it out when i reinstalled my new motor.

 

going outside right now to see if I can detect anything, looked there earlier but couldn't notice anything.
So in between the white box and the black box right? I'll check and come back later
thanks Nate

 

didn't see anything different than what I saw earlier, going to take a pic, maybe I'm looking at the wrong place. Sorry you have to hold my hand here, but never had an issue with AC so is all new to me

 

cold night ahead BUMP :)

 

your looking at the right spot.

That white box on the top left has a shaft that goes into the black box. you need to find out if this shaft is turning when you adjust the temp dial on the dash.with a flashlight, look in the gap between them, you'll see the squareish shaft in there. if its not moving you need a new one, called a blend door actuator. its a $60ish part.


read this to get a better idea of what im talking about.

Thanks again Nate.
Do you mean the black box underneath the white one right? There's a black/gray box on top of it but seems to be not attached to the white one in any way.
Will look at that again, and start to plan on how to remove the screw behind it :)

 

duhhh , ok, now seeing the pics on the linked thread it makes sense.
Thanks again

 

no problem!

 

F**K !Ordered the part few weeks ago, it got here yesterday and now I'm replacing it. I take the old actuator and it works :(

Any idea where to look next?
I'm going to replace it anyway, it's a pain in the butt to change and I'm 70% done, so I'd rather have a new part there since I already have it.

Any help here please?
thanks

 

Well, freaked out with no reason, I replaced the actuator with the new one and now there's HOT air again :)

I assume there old actuator was working but it was so weak that it couldn't swing the blend door. It worked find when plugged in but not attached to anything, once you put it back it won't spin.

The screw in the back is a b*tch, so I took a chisel and cut it along with the plastic post, I made a small hole in the plastic case but so tiny I patched it with tape.

Thanks a lot for your help, now I can go out more :)
