2013 Ford Expedition Temperature Blend Door Diagnosis

[@KBLIZZ333]

Thanks so much for another great video !! I can't begin to tell you how much you've helped me and my career as an aspiring Diag Tech. My first 20+ years in the automotive repair industry I just went with the flow, content with just swapping out the parts they told me to. Never asking why a part failed, or what led to the decision to replace it. Until I came across this KZbin channel, and a handful of others like it. Changed my life. So thank you again, for doing this for those of us who want to be better.

Hey Danner, quick useful tip for the Autel, after you've done the scan, tap the 'list' tab right next to the topology tab and it'll give you the same report as the report tab does however you'll see tabs next to the code description to shortcut straight to freeze frame data and shortcut straight to the module whereas the report tab doesn't 😁👌

[@ScannerDanner]

High amperage can be a frozen motor or the door itself. So amperage gives us direction but not a definitive of which of the two it would be. But that would be all you would need to 100% pull the dash right?

[@kurtkennedy5370]

Ive seen when these motors short out, they fry the module under the upper center console part, its like a half ass HVAC module. You put the new actuator in, and still have no opperation or it fails the calibration.

[@patrickzambori473]

after finding sufficient power and ground to the actuator motor at the module connector, I would have done a resistance check through the drive motor from the module end to confirm continuity on the wires and motor. If *that* was good, I would be dropping a bore scope down the duct if possible to see if there was an acorn or pencil jammed in the door.

The older ones had a self test, it would spit out codes. Crown vics are similar but if you dont mind some bloody knuckles you can install without taking out the dash (partially anyway).

[@machintelligence]

I had to replace the blend door on my 2009 Ranger. It stuck in the heat position and then finally failed in the vent/cool position. It was fairly accessible after removing the glove box. If it clicks but doesn't move, it can be lubricated, but mine was dead and had to be replaced. $40.00 part but not quite two hours for diagnosis and replacement. I guess it could have been worse.

[@bradnoyes7955]

28:00 driver's side reading is probably opposite because the actuator is mounted upside down/on the bottom of the housing compared to the passenger side mounted on top the housing.

Is there a good scan tool software for laptop with the adapter u can use instead of buying all these stand alone units ?

[@SmittySmithsonite]

Brilliant stuff as always, Paul & Caleb. This type of engineering always brings me to ranting ... That Expedition is what I like to call, "A-hole engineering" - prime example of it right there. This is how they basically extort you into another car payment. When your heat doesn't work and it's -14°F out, you're going to want to get it fixed (especially if the wifey is driving it -you're gonna hear about that!). When presented with a $2,000 quote to do the job, you throw in the towel and buy another poorly engineered, overpriced, s-box. And the cycle continues! ZERO incentive for automakers to change. Where did all the innovators go? Take a look at history - there were DOZENS of automakers in the early part of the 20th Century, each offering customers something the others couldn't. One by one, they all fell by the wayside, except for 3 (domestically, anyway). All these brilliant minds couldn't have just disappeared. Where did they all go? Sure makes you wonder. We've got Tesla ... but is that because he's making what the powers to be WANT him to make? Get the world on electric, and now someone can shut it all down at the flick of a switch! Hmmm ... lots of questions, few answers ...

[@jonathanhart54]

If there was a short to ground in one of those wires would it fry the module? Or is there a form of circuit protection that isn’t shown in the diagram? I’d image that the module uses the potentiometer to monitor movement and would cut power to the motor if it stopped moving unexpectedly to protect the circuit that way?

[@ScannerDanner]

Great insight. I would hope so (circuit protection if the signal stops moving) Yes, a short to ground would definitely hurt the driver unless there is some circuit protection.

[@blkthunderbolt]

I’m wondering how u edited the scanner screen into the video.

[@michaelkennedy2528]

Hey Paul, if I were to send you some files off a 2000 Ford Windstar 3.8 L that the engine shakes like crazy. We have had no less than 10 people take a shot at it and try to fix it, no luck.

[@bartscave]

But Paul, It's only 6.6 hours to remove transmission then torch cut a hole in the floor to replace the actuator (and hopefully catching the car on fire for the insurance.....)

[@bartscave]

I wonder if it would prove a stuck actuator by using a scope and a low amp clamp at the battery itself. A blip on the screen would indicate the command and wiring working but the actuator not.

[@ScannerDanner]

Absolutely you can but the problem at the battery is other stuff running at the same time will blur the picture

Would an Autel with the Oscilloscope accessory be a good starter scanner or would it be better to get a used Snapon Modis or Verus?

[@robertmedina6875]

The snapon has guided component tests that walk you through testing. I believe the autel does not have guided . Tests. I personally like the verus. Get the most recent update possible when buying snappy. I purchased mine from ebay. You can find on Facebook cheaper, however not very offen. Verus updates are over a grand a year! Dig deep! I hope this helps. Scannerdanner.com has great verus classes, well worth the price.

[@ScannerDanner]

I agree with Robert, but I do like my Autel Ultra scope too

[@nateb.1568]

@@ScannerDanner another benefit of the Snapon is that the scope and Scan Tool are all integrated into one tool without the need for a seperate box. A lot better for portability. Are there any other deciding factor that would support buying a used Snapon over an Autel? To me, it seems like the Snapon interface might be a bit more polished than Autels. And I like how the Snapon only lists modules and tests the car actually supports.

[@josephwash109]

It's not really necessary to check each motor wire individually with the test light. You could just connect each end to the motor control wires and then test the drivers that way. If the light illuminates when the temperature increase and decrease buttons are pressed, the drivers are good. Then, the few moments you save can be better used removing the dash. ;)

[@ScannerDanner]

Understand for sure, I prefer individual circuit tests for each driver. This would have been derived from a stepper motor where I have saw one failed driver on one of the 2 coils and without knowing for sure the direction or polarity being applied, the individual test was key. Now for a regular DC electric motor? You are right, by simply increasing the temp, you want to see the light, light and then the same thing when decreasing temp. I think when I was talking about this, I was thinking more along the stepper motor circuit. Thanks!

[@jonathanhart54]

Is there a reason why the potentiometer is draw as having 3 individual resistors rather than one big resistor representing the carbon strip? Or is that just how they chose to draw it?

[@ScannerDanner]

Not sure on this one, but it doesn't change the operation at all. First time I've seen one drawn this way too.
