Eatc confusion? Code 25 - which blend door actuator?

[Richg14]

I have a problem with my blend door actuator. I've done the eatc tests and receive code 25 error. I've checked the blend door itself for operation and all looks good and nothing broken. So all that is left to do is purchase a new one and install it....

However

There is a little mystery that I need help with. My ac/heater controls are electronic (digital controls) not a manual dial...I follow the instructions for eatc control and get the self diagnostics...but... When I look up my actuator, like at doorman...The part I have in my hand looks like the one they CALL MANUAL controls. The automatic one looks different. The reason this is important is my ac/heater controls have an automatic button that has never worked...

So do I have an eatc or a manual system? Does the doorman part 604-202, WHICH LOOKS LIKE THE PART I HAVE but labeled manual adjust the temperature when the automatic button is pressed?

Or would I get the doorman 604-201 which has is labeled for automatic but looks differently.

At the end of the day I am confused why I have an eatc and a system with an automatic button but have a manual actuator.

My vehicle is a 2000 ford explorer limited...

i'm pretty sure all the Limited's came with the Electronic Automatic Temperature Control (EATC). the manual control version had 3 twist knobs. no temp display or buttons.

Hi. Ten years later hope you still out there. I have the EXACT SAME situation! Wondering if you ever got that resolved. My name is Steve, (352) 212-9409. Man, I would be thrilled to hear from you.

Hello.

Hope you are still out there 10 years later. I have your EXACT SAME situation. Mine looks like the maual version that everyone has for sale, but mine is clearly labled on the original Ford OEM part, ATC. The 604-202 did not work for me, I bought one just to try it. Like you said, the 604- 201 shows for ATC, but it is physically different. Man, I hope you are still out there somewhere and would be willing to talk to me. I love my 2000 Mountaineer, and want to keeep it working right.

The base is different you should be able to remove the 402 version from its base and then it works with your eatc

However if you have the original blend door actuator and it is moving back and forth properly when removed from the hvac box… well then it’s quite possible
You are getting the code because the blend door itself is physically broken (common)

See your other thread

This rockauto link shows the available actuators

The Dorman 402
Unit unhooks from the base with 4 little
Clips/ snaps then it should fit your truck
However like I said in the other thread all you probably really need is the little nylon gear from inside any aftermarket or factory blend door actuator
