EATC (Automatic A/C) codes?
I have an Explorer with automatic A/C. The blend door actuator broke (a gear inside) so I replace it with a Dorman part (could not find the Ford ones anywhere). Part #604-202, looks identical and fits. But... doesn't work.
If I do the EATC test (OFF+FLOOR, then AUTOMATIC), the display shows error coded 024, 025, 052.
What is the meaning of those?

I don't have the manual in front of me but I'm pretty sure 24 and 25 are Blend Door Actuator codes. Did you remember to plug the wiring harness into the new actuator?
Yes, I've done that before on my Lincoln Mark VII. The whole inst. panel had to come back out.
Did you disconnect the battery while you were working on the system? If not, it may need to be reset.

Yes, exiting the self test by hitting Defrost will clear the codes.
Code 24 and 25 are Blend Door failure codes. According to the manual:
-Code 25 is a Hard Fault. No actual description given.
-Code 24 is a Runtime fault, Blend Door Failure.
The code 52 that you mentioned in your first post is a Runtime Fault:
-Solar Radiation (Sun Load) Sensor short to ground.
The shop manual then references corresponding Bxxx codes for electrical pinpoint test steps:
Codes 24 and 25: See code B1429.
Code 52: See code B1261.
You will need a DMM and the shop manual for these tests. Way too much info to type.
When you had it apart, were you able to move the blend door by hand?
Are you sure you reconnected the wiring to the actuator?

Thanks for the replies. Updates:
1. I have Automatic Temperature Controls (ETAC). I already returned the Dorman controller since I did found out that on their site was listed for "manual" A/C operation - didn't show that up in the parts store. The one that Dorman lists as "automatic" is 604-201 was not available on the parts store in my area, just online. I don't know if I should risk ordering it online.
2. I will try tommorow to ask the local Ford dealership if they have an OE one.
