Does anyone know where I can find a replacement EATC unit/module for my truck? The part number is 2l3h-19c933-aa, which I believe is different from the expedition/navigator units with the part number XL7H-19C933-AC (probably has something to do with the rear defrost I assume)


The XL7H-19C933-AC units are pretty easy to find and are considerable cheaper, but I'm having trouble tracking down a 2l3h-19c933-aa for my truck. My unit is not repairable, already tried. Junk yards around here don't have anything that will work, and eBay gets a little pricey ($250).

 

Bump, anyone have any ideas?


Could I swap in the vacuum board from a different unit into my EATC? So use my stock EATC control board, display, etc. and swap in the vacuum solenoid assembly from a different vehicle???

 

Did you try Rockauto.com? Next, also try Amazon.com. They should have the cross-ref for the part #. Should be able to do better than $250.

 

Rockauto didn't have my part number, but they did have the expy/nav part for $240 (plus $200 core charge). Amazon has a used/refurbished one for $189.

 

$797.12 from Ford.

 

What's it doing? Why are you replacing it?

 

It's the typical "defrost only" issue. (My current unit is not repairable, as it doesn't have removable vacuum solenoids.)

 

WTF!!

Is it capable of doing a Self Test mode?

 

I know, I had to ask the parts guy three times to make sure he had the right part.

 

Air blows only on defrost vent? It can be repaired cheaply if that's the problem.
